It appears that there maybe an issue with Pie and bar charts appearing within Chrome browsers. I am on a mac and can not view pie or bar charts. The area where the chart appears is white, however when I move my mouse over the area I get a pop-over with data in it. It seems to be a rendering issue
Line graphs seem to work
I have tried this in a number of browsers (Safari and Firefox) which all seem to work except for Chrome Vivaldi.
My setup is:
Mac OS X 10.11.6
Chrome version Version 60.0.3112.113 (Official Build) (64-bit)
Vivaldi (1.12.955.36 (Stable channel) (64-bit))
Interestingly, I have tried viewing some of the samples on the jqPlot website within chrome and they do not seem to work either.
