Help your users pay attention to key data in a bar chart. Customize your labels color, font, size and position (top or bottom) of the bar. Users can drill down by clicking on labels or the bar itself.
Bar styles include stacked, side-by-side (Clustered), and overlapping (a.k.a bar in bar.) Overlapping bars help visualize the comparison between two things when one is inherently a part of the other.
