spateo.plotting.color_label(adata: anndata.AnnData, basis='contour', color_key: list | None = None, dpi: int = 100, boundary_width: float = 0.2, boundary_color='black', figsize=(6, 6), aspect: str = 'equal', *args, **kwargs)[source]¶

Color the segmented cells with different colors.

Parameters:

adata: ~anndata.AnnData An Annodata object.
basis: str The key to the column in the adata.obs, from which the contour of the cell segmentation will be generated.
color_key: list List of colors. If the number of labels exceeds the number of colors, then the colors are cycled.
dpi: float, (default: 100.0) The resolution of the figure in dots-per-inch. Dots per inches (dpi) determines how many pixels the figure comprises. dpi is different from ppi or points per inches. Note that most elements like lines, markers, texts have a size given in points so you can convert the points to inches. Matplotlib figures use Points per inch (ppi) of 72. A line with thickness 1 point will be 1./72. inch wide. A text with fontsize 12 points will be 12./72. inch height. Of course if you change the figure size in inches, points will not change, so a larger figure in inches still has the same size of the elements.Changing the figure size is thus like taking a piece of paper of a different size. Doing so, would of course not change the width of the line drawn with the same pen. On the other hand, changing the dpi scales those elements. At 72 dpi, a line of 1 point size is one pixel strong. At 144 dpi, this line is 2 pixels strong. A larger dpi will therefore act like a magnifying glass. All elements are scaled by the magnifying power of the lens. see more details at answer 2 by @ImportanceOfBeingErnest: https://stackoverflow.com/questions/47633546/relationship-between-dpi-and-figure-size
boundary_width: float, (default: 0.2) The line width of boundary.
boundary_color: (default: “black”) The color value of boundary.
figsize: tuple The size of the figure in inches.
aspect: str Set the aspect of the axis scaling, i.e. the ratio of y-unit to x-unit. In physical spatial plot, the default is ‘equal’. See more details at: https://matplotlib.org/stable/api/_as_gen/matplotlib.axes.Axes.set_aspect.html

Makes a dot plot of the expression values of var_names. For each var_name and each groupby category a dot is plotted. Each dot represents two values: mean expression within each category (visualized by color) and fraction of cells expressing the var_name in the category (visualized by the size of the dot). If groupby is not given, the dotplot assumes that all data belongs to a single category.

Parameters:

adata: object of class anndata.AnnData
var_names: Should be a subset of adata.var_names
cat_key: The key(s) in .obs of the grouping to consider. Should be a categorical observation; if not, will be subdivided into ‘num_categories’.
num_categories: Only used if groupby observation is not categorical. This value determines the number of groups into which the groupby observation should be subdivided.
cell_cell_dp: Set True to initialize specialized cell-cell dotplot instead of gene expression dotplot
delta: Only used if ‘cell_cell_dp’ is True- distance between the largest value to consider and the smallest value to consider (see ‘minn’ parameter below)
minn: Only used if ‘cell_cell_dp’ is True- for the dot size legend, sets the value corresponding to the smallest dot on the legend
alpha: Only used if ‘cell_cell_dp’ is True- significance threshold. If given, all elements w/ p-values <= ‘alpha’ will be marked by rings instead of dots.
prescale_adata: Set True to indicate that AnnData object should be scaled- if so, will use ‘delta’ and ‘minn’ to do so. If False, will proceed as though adata has already been processed as needed.
expression_cutoff: Used for binarizing feature expression- feature is considered to be expressed only if the expression value is greater than this threshold
mean_only_expressed: If True, gene expression is averaged only over the cells expressing the given features
cmap: Name of Matplotlib color map to use
dot_max: If none, the maximum dot size is set to the maximum fraction value found (e.g. 0.6). If given, the value should be a number between 0 and 1. All fractions larger than dot_max are clipped to this value.
dot_min: If none, the minimum dot size is set to 0. If given, the value should be a number between 0 and 1. All fractions smaller than dot_min are clipped to this value.
standard_scale: Whether or not to standardize that dimension between 0 and 1, meaning for each variable or group, subtract the minimum and divide each by its maximum. ‘val’ or ‘group’ is used to specify whether this should be done over variables or groups.
smallest_dot: If None, the smallest dot has size 0. All expression fractions with dot_min are plotted with this size.
largest_dot: If None, the largest dot has size 200. All expression fractions with dot_max are plotted with this size.
title: Title for the entire plot
colorbar_title: Title for the color legend. If None will use generic default title
size_title: Title for the dot size legend. If None will use generic default title
figsize: Sets width and height of figure window
dendrogram: If True, adds dendrogram to plot. Will do the same thing if string is given here, but will recompute dendrogram and save using this argument to set key in .uns.
gene_symbols_key: Key in .var containing gene symbols
var_group_positions: Each item in the list should contain the start and end position that the bracket should cover. Eg. [(0, 4), (5, 8)] means that there are two brackets, one for the var_names in positions 0-4 and other for positions 5-8
var_group_labels: List of group labels for the variable names (e.g. can group var_names in positions 0-4 as being “group A”)
var_group_rotation: Rotation in degrees of the variable name labels. If not given, small labels (<4 characters) are not rotated, but otherwise labels are rotated 90 degrees.
layer: Key in .layers specifying layer to use. If not given, will use .X.
swap_axes: Set True to switch what is plotted on the x- and y-axes
dot_color_df: Pre-prepared dataframe with features as indices, categories as columns, and indices corresponding to color intensities
save_show_or_return: Options: “save”, “show”, “return”, “both”, “all” - “both” for save and show
save_kwargs: A dictionary that will passed to the save_fig function. By default it is an empty dictionary and the save_fig function will use the {“path”: None, “prefix”: ‘scatter’, “dpi”: None, “ext”: ‘pdf’, “transparent”: True, “close”: True, “verbose”: True} as its parameters. But to change any of these parameters, this dictionary can be used to do so.
ax: Pre-initialized axis object to plot on
vmin: The data value that defines 0.0 in the normalization. Defaults to the min value of the dataset.
vmax: The data value that defines 1.0 in the normalization. Defaults to the the max value of the dataset.
vcenter: The data value that defines 0.5 in the normalization
norm: Optional already-initialized normalizing object that scales data, typically into the interval [0, 1], for the purposes of mapping to color intensities for plotting. Do not pass both ‘norm’ and ‘vmin’/’vmax’, etc.
kwargs: Additional keyword arguments passed to matplotlib.pyplot.scatter()

Geometry plot for physical coordinates of each cell.

Parameters:

adata: an Annodata object that contain the physical coordinates for each bin/cell, etc.
basis: The key to the column in adata.obs from which the contour of the cell segmentation will be generated.
color: Any or any list of column names or gene name, etc. that will be used for coloring cells. If color is not None, stack_genes will be disabled automatically because color can contain non numerical values.
genes: The gene list that will be used to plot the gene expression on the same scatter plot. Each gene will have a different color. Can be a single gene name string and we will convert it to a list.

Note that most elements like lines, markers, texts have a size given in points so you can convert the points to inches. Matplotlib figures use Points per inch (ppi) of 72. A line with thickness 1 point will be 1./72. inch wide. A text with fontsize 12 points will be 12./72. inch height. Of course if you change the figure size in inches, points will not change, so a larger figure in inches still has the same size of the elements.Changing the figure size is thus like taking a piece of paper of a different size. Doing so, would of course not change the width of the line drawn with the same pen. On the other hand, changing the dpi scales those elements. At 72 dpi, a line of 1 point size is one pixel strong. At 144 dpi, this line is 2 pixels strong. A larger dpi will therefore act like a magnifying glass. All elements are scaled by the magnifying power of the lens. see more details at answer 2 by @ImportanceOfBeingErnest: https://stackoverflow.com/questions/47633546/relationship-between-dpi-and-figure-size

Plot an embedding as points. Currently, this only works for 2D embeddings. While there are many optional parameters to further control and tailor the plotting, you need only pass in the trained/fit umap model to get results. This plot utility will attempt to do the hard work of avoiding overplotting issues, and make it easy to automatically colour points by a categorical labelling or numeric values. This method is intended to be used within a Jupyter notebook with %matplotlib inline.

Parameters:

adata

AnnData an Anndata object

basis

str The reduced dimension.

vf_key

Optional, key in .obsm containing vector field information

X_grid

Optional, array containing grid points for vector field plots

V

Optional, array containing vector fields

x

int (default: 0) The column index of the low dimensional embedding for the x-axis.

y

int (default: 1) The column index of the low dimensional embedding for the y-axis.

color

string (default: ntr) Any column names or gene expression, etc. that will be used for coloring cells.

layer

str (default: X) The layer of data to use for the scatter plot.

highlights

list (default: None) Which color group will be highlighted. if highlights is a list of lists - each list is relate to each color element.

labels

array, shape (n_samples,) (optional, default None) An array of labels (assumed integer or categorical), one for each data sample. This will be used for coloring the points in the plot according to their label. Note that this option is mutually exclusive to the values option.

values

array, shape (n_samples,) (optional, default None) An array of values (assumed float or continuous), one for each sample. This will be used for coloring the points in the plot according to a colorscale associated to the total range of values. Note that this option is mutually exclusive to the labels option.

theme

string (optional, default None) A color theme to use for plotting. A small set of predefined themes are provided which have relatively good aesthetics. Available themes are:

’blue’

’red’

’green’

’inferno’

’fire’

’viridis’

’darkblue’

’darkred’

’darkgreen’

cmap

string (optional, default ‘Blues’) The name of a matplotlib colormap to use for coloring or shading points. If no labels or values are passed this will be used for shading points according to density (largely only of relevance for very large datasets). If values are passed this will be used for shading according the value. Note that if theme is passed then this value will be overridden by the corresponding option of the theme.

color_key

dict or array, shape (n_categories) (optional, default None) A way to assign colors to categoricals. This can either be an explicit dict mapping labels to colors (as strings of form ‘#RRGGBB’), or an array like object providing one color for each distinct category being provided in labels. Either way this mapping will be used to color points according to the label. Note that if theme is passed then this value will be overridden by the corresponding option of the theme.

color_key_cmap

The name of a matplotlib colormap to use for categorical coloring. If an explicit color_key is not given a color mapping for categories can be generated from the label list and selecting a matching list of colors from the given colormap. Note that if theme is passed then this value will be overridden by the corresponding option of the theme.

background

string or None (optional, default ‘None`) The color of the background. Usually this will be either ‘white’ or ‘black’, but any color name will work. Ideally one wants to match this appropriately to the colors being used for points etc. This is one of the things that themes handle for you. Note that if theme is passed then this value will be overridden by the corresponding option of the theme.

ncols

int (optional, default 4) Number of columns for the figure.

pointsize

None or float (default: None) The scale of the point size. Actual point cell size is calculated as 500.0 / np.sqrt(adata.shape[0]) * pointsize

aggregate

str or None (default: None) The column in adata.obs that will be used to aggregate data points.

show_arrowed_spines

bool (optional, default False) Whether to show a pair of arrowed spines representing the basis of the scatter is currently using.

ax

matplotlib.Axis (optional, default None) The matplotlib axes object where new plots will be added to. Only applicable to drawing a single component.

sort

str (optional, default raw) The method to reorder data so that high values points will be on top of background points. Can be one of {‘raw’, ‘abs’, ‘neg’}, i.e. sorted by raw data, sort by absolute values or sort by negative values.

save_show_or_return

Whether to save, show or return the figure. If “both”, it will save and plot the figure at the same time. If “all”, the figure will be saved, displayed and the associated axis and other object will be return.

save_kwargs

A dictionary that will be passed to the save_fig function. By default, it is an empty dictionary and the save_fig function will use the {“path”: None, “prefix”: ‘scatter’, “dpi”: None, “ext”: ‘pdf’, “transparent”: True, “close”: True, “verbose”: True} as its parameters. Otherwise, you can provide a dictionary that properly modify those keys according to your needs.

return_all

bool (default: False) Whether to return all the scatter related variables. Default is False.

add_gamma_fit

bool (default: False) Whether to add the line of the gamma fitting. This will automatically turn on if basis points to gene names and those genes have went through gamma fitting.

frontier

bool (default: False) Whether to add the frontier. Scatter plots can be enhanced by using transparency (alpha) in order to show area of high density and multiple scatter plots can be used to delineate a frontier. See matplotlib tips & tricks cheatsheet (https://github.com/matplotlib/cheatsheets). Originally inspired by figures from scEU-seq paper: https://science.sciencemag.org/content/367/6482/1151. If contour is set to be True, frontier will be ignored as contour also add an outlier for data points.

contour

bool (default: False) Whether to add an countor on top of scatter plots. We use tricontourf to plot contour for non-gridded data. The shapely package was used to create a polygon of the concave hull of the scatters. With the polygon we then check if the mean of the triangulated points are within the polygon and use this as our condition to form the mask to create the contour. We also add the polygon shape as a frontier of the data point (similar to when setting frontier = True). When the color of the data points is continuous, we will use the same cmap as for the scatter points by default, when color is categorical, no contour will be drawn but just the polygon. cmap can be set with ccmap argument. See below. This has recently changed to use seaborn’s kdeplot.

ccmap

str or None (default: None) The name of a matplotlib colormap to use for coloring or shading points the contour. See above.

calpha

float (default: 0.4) Contour alpha value passed into sns.kdeplot. The value should be inbetween [0, 1]

sym_c

bool (default: False) Whether do you want to make the limits of continuous color to be symmetric, normally this should be used for plotting velocity, jacobian, curl, divergence or other types of data with both positive or negative values.

smooth

bool or int (default: False) Whether do you want to further smooth data and how much smoothing do you want. If it is False, no smoothing will be applied. If True, smoothing based on one step diffusion of connectivity matrix (.uns[‘moment_cnn’] will be applied. If a number larger than 1, smoothing will based on `smooth steps of diffusion.

dpi

float, (default: 100.0) The resolution of the figure in dots-per-inch. Dots per inches (dpi) determines how many pixels the figure comprises. dpi is different from ppi or points per inches. Note that most elements like lines, markers, texts have a size given in points so you can convert the points to inches. Matplotlib figures use Points per inch (ppi) of 72. A line with thickness 1 point will be 1./72. inch wide. A text with fontsize 12 points will be 12./72. inch heigh. Of course if you change the figure size in inches, points will not change, so a larger figure in inches still has the same size of the elements.Changing the figure size is thus like taking a piece of paper of a different size. Doing so, would of course not change the width of the line drawn with the same pen. On the other hand, changing the dpi scales those elements. At 72 dpi, a line of 1 point size is one pixel strong. At 144 dpi, this line is 2 pixels strong. A larger dpi will therefore act like a magnifying glass. All elements are scaled by the magnifying power of the lens. see more details at answer 2 by @ImportanceOfBeingErnest: https://stackoverflow.com/questions/47633546/relationship-between-dpi-and-figure-size

inset_dict

dict (default: {}) A dictionary of parameters in inset_ax. Example, something like {“width”: “5%”, “height”: “50%”, “loc”: ‘lower left’, “bbox_to_anchor”: (0.85, 0.90, 0.145, 0.145), “bbox_transform”: ax.transAxes, “borderpad”: 0} See more details at https://matplotlib.org/api/_as_gen/mpl_toolkits.axes_grid1.inset_locator.inset_axes.html or https://stackoverflow.com/questions/39803385/what-does-a-4-element-tuple-argument-for-bbox-to-anchor-mean -in-matplotlib

marker

str (default: None) The marker style. marker can be either an instance of the class or the text shorthand for a particular marker. See matplotlib.markers for more information about marker styles.

pointsize: The size of the points on the scatter plot
dpi: float, (default: 100.0) The resolution of the figure in dots-per-inch. Dots per inches (dpi) determines how many pixels the figure comprises. dpi is different from ppi or points per inches. Note that most elements like lines, markers, texts have a size given in points so you can convert the points to inches. Matplotlib figures use Points per inch (ppi) of 72. A line with thickness 1 point will be 1./72. inch wide. A text with fontsize 12 points will be 12./72. inch heigh. Of course if you change the figure size in inches, points will not change, so a larger figure in inches still has the same size of the elements.Changing the figure size is thus like taking a piece of paper of a different size. Doing so, would of course not change the width of the line drawn with the same pen. On the other hand, changing the dpi scales those elements. At 72 dpi, a line of 1 point size is one pixel strong. At 144 dpi, this line is 2 pixels strong. A larger dpi will therefore act like a magnifying glass. All elements are scaled by the magnifying power of the lens. see more details at answer 2 by @ImportanceOfBeingErnest: https://stackoverflow.com/questions/47633546/relationship-between-dpi-and-figure-size
