pieChart and undefined font for labelWiring in MSIE

I found a bug in IE7,8 when I tried render pieChart with labelStyle set to "column". Problem appears in IE only, and seems to be related to theme. Font that should be used in case of rendering wiring and its label is undefined.

Problem seems to be here, in plot2d/Pie.js

taFont = "font" in this.opt ? this.opt.font : t.axis.font,

What happens when user does not specify font and axis.font is not specified in theme?...

We are rendering pie chart which really does not have any axis, but has series of data, therefore much better would be to ask for series theme settings.

Patch file attached.

Good catch. Actually theme.axis.font is even never expected to exist. Even if we want to take that information on the axis this is probably more theme.axis.tick.font as nothing in the theming specification talks about a font on the axis itself. So your patch is maybe not 100% correct. That said I'll try to get that fixed for 1.8.

Ok, I think the right fix will be to use the same (series) font in all cases and never rely on axis font.

In [29205]:

fixes #15583. Make sure to consistently use for font theme.series.font and not sometimes theme.axis.font which does not exit (+ other small cleanups).
