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.
