I'm trying to represent my data using a bar graph, the data being displayed is goodVotes, neutralVotes and badVotes on the x-axis for each of my pieces of data (records in an sqlite3 database).

I wish the "bookName" of each record to be displayed on the x axis of the BAR GRAPH along with it's corresponding good, neutral and bad votes. Then the bars to be displayed depending on the amoun of votes they have. I want sizing to be (width) to be based on screen size (i have a screenWidth and screenHeight variable already set up) as i have 15 different x-axis variables each contaiing good, neutral and bad votes section.

Every gui problem has already been solved by vegaseat. Type tkinter bargraph in daniweb's search form and you'll find many examples, like this one, still fully working after 7 years !

y = [12600, 13400, 16350, 17100, 14700]
