4. Divided Bar graphs๏
Divided bar graphs are a bar graph in sections, which often total to 100. (100%)
The python file to make divided bar graphs is below.
The required LaTeX files are below.
The custom python modules required are:

4.1.4. Txt file๏
The .txt file is shown below.
3 lines store data:
line 1: the plot title
line 2: a comma separated sequence of numeric values
line 3: a comma separated sequence of labels for the values
A maximum number of entries for line 2 and line 3 is 10.
Some characters need to be escaped manually such as & for & and % for % if used in line 1 or 3.
