   • Stacked Bar Chart With Selection Using Altair in Python

     Prerequisite: Altair

     In this article, We will see Stacked Bar Chart With Selection with Altair python. It is a declarative and interactive visualization tool for Python, based on Visualization Grammar (VeGa), It is simple, user-friendly, and moreover provides clearly interpretable charts. It supports a wide variety of charts like bar, line, scatter, box, violin, and other charts in an interactive way.  Let’s discuss how to create a stacked bar chart with a selection to highlight a particular stack of the bar chart.

     Installation

     The following command can be used to install Altair and Pandas like any other python library:

     pip install altairpip install pandaspip install altair_viewer

     Functions Used

     • The altair.selection_single() specify the type of selection inside the select method. The method takes parameters that are discussed below.

     Syntax: altair.selection_single(type, encodings)

   • Python - Altair - Stacked Bar Chart With Selection

     Top Answer

     Answered May 17, 2019 · 7 votes

     Yes, this is possible. You can specify in the selector which encodings you would like it to respond to; to respond to individual sections of the stacked bar, specify x and color.

     Here's an example:

     import altair as altfrom vega_datasets import data-source = data.barley()selector = alt.selection_single(encodings=['x', 'color'])alt.Chart(source).mark_bar().encode( x='variety', y='sum(yield)', color=alt.condition(selector, 'site', alt.value('lightgray'))).add_selection( selector)

     Theres are great solution for similar question to design multi index labels here. You can use the same parameters of plot with ax=fig.gca() in that solution i.e

     import matplotlib.pyplot as plt-# add_line,label_len,label_group_bar_table from https://stackoverflow.com/a/39502106/4800652-fig = plt.figure()ax = fig.add_subplot(111)#Your df.plot code with ax parameter heredf.plot.bar(stacked=True, rot=0, alpha=0.5, legend=False, ax=fig.gca())labels = ['' for item in ax.get_xticklabels()]ax.set_xticklabels(labels)ax.set_xlabel('')label_group_bar_table(ax, df)fig.subplots_adjust(bottom=.1*df.index.nlevels)plt.show()
