Description	When showing charts at the statistics feature some of the bars are hardly visible. Only when hovering a bar with the mouse, the bar is shown in a darker way, see attached screen shot. The bar chart uses the color of the first bar for all bars. According to the legend, there should be multiple, different colors, see screenshot.
Steps To Reproduce	Call the statistics featrue with a survey with multiple questions. Enable "View summary of all fields" and "Show graphs". Then check the graphs. Some bars are visible, other use very light colors and can sometimes hardly be seen.

Mazi 2019-10-21 09:12 updater ~54125	@cdorin, this is an issue that should be simple to fix. Since a customer uses these statistics a lot and sometimes bars can't be seen, can you assign this with proper priority? Thanks!

Mazi 2019-10-21 09:16 updater ~54126	I just tested with an older version (3.17.7) and there both issues did NOT show up. Even the tooltip for a bar looks better, see screenshot. stats_ls3_17.png (66,989 bytes) stats_ls3_17.png (66,989 bytes)

Mazi 2019-10-30 09:07 updater ~54260	@cdorin, this is a fix required urgently by one of our customers. Is there a chance to include the fix to the next release? If you lack resources, can you point me to the file that needs to be adjusted? As outlined above, at a previous version this looked fine so that seems to have been changed recently. Maybe you find the related commit and can hand us a link so we can try providding a fix?
