So, I haven't found anything that could solve my problem. The issue is the following, I have a number of entries like: A, B, C, which belong to a group "Letters", I also have a symbol I, which is designated as I-Roman number and also there's a group of entries 1, 2, 3 which are "Arabic numbers". Several values belong to that group. import pandas as pd import matplotlib.pyplot as plt df = pd.read_csv('Test.csv', sep=';') df.head() print(df) #df.plot(x="nameEntry", y="valueEntry", kind="bar") #plt.show() fig, ax = plt.subplots() ax.bar(df["nameEntry"], df["valueEntry"]) fig.subplots_adjust(bottom=0.28) plt.xticks(rotation=45) plt.show() Here's the code, which I use. And the output: What I want, however, is: What I want is to create a unifying bracket (I do not insist on curly brackets, or any brackets, any uniting sign/feature is acceptable) that describes the subentries of a group together. Is there any way to do this programmatically using matplotlib? The data: nameEntry;valueEntry A;45216 B;21739 C;32179 I - Roman number;73218 1;819023 2;291 3;38910 Continue reading...
