Hi there,
first of all: Great Plugin, I just love those charts!
But I think I found a Bug today:
Im using a really simple Bar-Chart on my Site (only max. 4 horizontal bars) and im just doing the Mobile-Frontend.
Im using Googles Chrome Mobile-Version on my Samsung Galaxy S3 with Android 4.1.2.
When I open the Bar-Chart, all Texts (Axis-Titles, Labels), Grids and additional Information is missing, the only thing rendered is the bar itself.
It looks kind of like a white rectangle with smaller coloured rectangles inside, so is not really useful that way ;).
It works perfectly fine with the native android browser, so it seems to be a chrome-specific problem.
Hope this helps. Keep up the good work!
