Discover:Plot more than 15 items on chart

I really like the improved chart graphics that's been recently introduced in to Discover.  However, it's pretty frustrating that I can only plot 15 items/bars in a ranked report.

Please can you consider extending this?  Ideally I'd like to be able to plot 100+ items.

I'm guessing that the limitation is because you are concerned about not being able to display a label for each item? However, for what I want to use this for this wouldn't be a concern.
