Pie-chart widgets render too big

[vitekpetr]

Hello,

I have installed Icinga 2 dashboard and I have an issue with the pie-chart widgets and labels.
The widgets render too big for the box and the labes are in grey color when they should be in white.

There is an error in browser develepment console. Maybe it has something to do with the issue.
