Edited by: bouziot, 2020.03
Parameters
----------
cptf : str, open file or url handle
path to .cpt file
name : str, optional
name for color map
if not provided, the file name will be used
method : str, suggests the method to use.
If method = 'cdict', generates the LinearSegmentedColormap using a color dictionary (cdict), disregarding any value in N.
If method = 'list', generates the LinearSegmentedColor using the .from_list() method, passing a list of (value, (r,g,b)) tuples obtained from the cpt file. This allows the selection of colormap resolution by the user, using the N parameter
N : int, the number of colors in the colormap. Only useful when method='list'.
ret_cmap_type: str, the type of matplotlib cmap object to be returned. Accepts either 'LinearSegmented', which returns a matplotlib.colors.LinearSegmentedColormap, or 'Listed', which returns a ListedColormap
In case 'Listed' is selected, the method argument from the user is ignored and method is set to 'list' ('Linear' doesn't work with 'cdict').
N is then passed to matplotlib.colors.ListedColormap().
- If N is set to None: all colors of the cpt file will be returned as a list.
- In case of a user-defined N, colors will be truncated or extended by repetition (see matplotlib.colors.ListedColormap).
Returns
-------

Scatter plot of Sensitivity value across cells.
Parameters
----------
adata: :class:`~anndata.AnnData`
an Annodata object with Jacobian matrix estimated.
regulators: `list` or `None` (default: `None`)
The list of genes that will be used as regulators for plotting the Jacobian heatmap, only limited to genes
that have already performed Jacobian analysis.
effectors: `List` or `None` (default: `None`)
The list of genes that will be used as targets for plotting the Jacobian heatmap, only limited to genes
that have already performed Jacobian analysis.
basis: `str` (default: `umap`)
The reduced dimension basis.
skey: `str` (default: `sensitivity`)
The key to the sensitivity dictionary in .uns.
s_basis: `str` (default: `pca`)
The reduced dimension space that will be used to calculate the jacobian matrix.
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.
highlights: `list` (default: None)
Which color group will be highlighted. if highligts is a list of lists - each list is relate to each color element.
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.
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.
figsize: `None` or `[float, float]` (default: (6, 4))
The width and height of each panel in the figure.
show_legend: bool (optional, default True)
Whether to display a legend of the labels
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.
sym_c: `bool` (default: `True`)
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.
sort: `str` (optional, default `abs`)
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.
show_arrowed_spines: bool (optional, default False)
Whether to show a pair of arrowed spines representing the basis of the scatter is currently using.
stacked_fraction: bool (default: False)
If True the jacobian will be represented as a stacked fraction in the title, otherwise a linear fraction
style is used.
save_show_or_return: `str` {'save', 'show', 'return'} (default: `show`)
Whether to save, show or return the figure.
save_kwargs: `dict` (default: `{}`)
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. Otherwise you can provide a dictionary that properly
modify those keys according to your needs.
kwargs:
Additional arguments passed to plt._matplotlib_points.
Returns
-------
Nothing but plots the n_source x n_targets scatter plots of low dimensional embedding of the adata object, each
corresponds to one element in the Jacobian matrix for all sampled cells.
Examples
--------
>>> import dynamo as dyn
>>> adata = dyn.sample_data.hgForebrainGlutamatergic()
>>> adata = dyn.pp.recipe_monocle(adata)
>>> dyn.tl.dynamics(adata)
>>> dyn.vf.VectorField(adata, basis='pca')
>>> valid_gene_list = adata[:, adata.var.use_for_transition].var.index[:2]
>>> dyn.vf.sensitivity(adata, regulators=valid_gene_list[0], effectors=valid_gene_list[1])
>>> dyn.pl.sensitivity(adata)

"""Bubble plots generalized to velocity, acceleration, curvature.
It supports either the `dot` or `violin` plot mode. This function is loosely based on
https://github.com/QuKunLab/COVID-19/blob/master/step3_plot_umap_and_marker_gene_expression.ipynb
# add sorting
Parameters
----------
adata: :class:`~anndata.AnnData`
an Annodata object
genes: `list`
The gene list, i.e. marker gene or top acceleration, curvature genes, etc.
group: `str`
The column key in `adata.obs` that will be used to group cells.
gene_order: `None` or `list` (default: `None`)
The gene groups order that will show up in the resulting bubble plot.
group_order: `None` or `list` (default: `None`)
The cells groups order that will show up in the resulting bubble plot.
layer: `None` or `str` (default: `None`)
The layer of data to use for the bubble plot.
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: string (optional, default 'Spectral')
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.
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`
vmin: `float` (default: `0`)
The percentage of minimal value to consider.
vmax: `float` (default: `100`)
The percentage of maximal value to consider.
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.
alpha: `float` (default: `0.8`)
alpha value of the plot
edgecolor: `str` or `None` (default: `None`)
The color of the edge of the dots when type is to be `dot`.
linewidth: `str` or `None` (default: `None`)
The width of the edge of the dots when type is to be `dot`.
type: `str` (default: `violin`)
The type of the bubble plot, one of `{'violin', 'dot'}`.
figsize: `None` or `[float, float]` (default: None)
The width and height of a figure.
sort: `str` (default: `diagnol`)
The method for sorting genes. Not implemented. Need to implement in 2021.
transpose: `bool` (default: `False`)
Whether to transpose the row/column of the resulting bubble plot. Gene and cell types are on x/y-axis by
default.
rotate_xlabel: `float` (default: `horizontal`)
The angel to rotate the x-label.
rotate_ylabel: `float` (default: `horizontal`)
The angel to rotate the y-label.
save_show_or_return: `str` {'save', 'show', 'return'} (default: `show`)
Whether to save, show or return the figure.
save_kwargs: `dict` (default: `{}`)
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. Otherwise you can provide a dictionary that properly modify those keys
according to your needs.
kwargs:
Additional arguments passed to plt.scatters or sns.violinplot.
Returns
-------
Nothing but plot the bubble plots.
