Heatmap

missionbio.plotting.heatmap.Heatmap

class Heatmap(data: DataFrame, y_groups: Sequence, x_groups: Optional[Sequence] = None, palette: Optional[Dict] = None, ytick_proportions: bool = False, title: str = '')

Heatmap with options for grouping rows/cols.

The xaxis groups (x_groups) or the grouping of columns is represented by appropriate tickvalues on the xaxis. The yaxis groups (y_groups) or the grouping of rows is represented by an extra column showing the color for each group category.

Snippets

>>> from missionbio.plotting.heatmap import Heatmap
>>> import numpy as np
>>> import pandas as pd
>>> data = pd.DataFrame(np.arange(10).reshape(5, 2))
>>> hm = Heatmap(data, y_groups=["a", "a", "a", "b", "b"])
>>> hm.draw()

Functions

Usually, only the draw() method is needed. The other methods are used internally by draw(). They can also be used to create complex custom plots as done in MultiMap.

draw()	Create the heatmap figure.
label_trace([name])	Parameters:
data_trace([name])	Parameters:
label_lines_trace([name])	Parameters:
data_lines_trace(vertical[, name])	Parameters:
set_yticks(fig)	Set the yaxis tickvalues.
set_xticks(fig[, tick_axis, overlay_axis])	Set the xaxis tickvalues.
coloraxis([colorscale])	Generate the coloraxis for the plot.
set_ticks(axis, groups[, proportions])	Set the tickvalues as the unique values in groups.
annotation(text[, xref, yref])	Create an annotation which can be added on top of the heatmap.
is_contiguous(labels)	Parameters:

Parameters:

datapd.DataFrame

The dataframe whose values are to be plotted. The index name is used for the title of the colorbar, the column names are shown on hovering over the heatmap.

y_groupsnp.ndarray

The labels for each row.

x_groupsnp.ndarray

The label for each column. These must be contiguous. For example, [“1”, “2”, “2”] is permitted, but [“1”, “2”, “1”] is not.

paletteOptional[Dict]

The dictionary with the color for each unique value in y_groups.

ytick_proportionsbool

Whether to show the fraction of rows of each y_group on the y-axis ticks.

titlestr

The title of the plot
