RadLegendView height



I use RadPieChart in my app and I’m facing a problem :
I can specify the height of the chart in the parent tag : <RadPieChart height="300"> so the child <DonutSeries> is of desired size. But then the legend is of same height, which is problematic since I want it to display more results than 300px can handle in the <RadLegendView> but still have a reasonable medium size chart (so limit it to 300px).
So my question is does someone knows a workaround ? is this a real issue ?
Ideally I’d like the RadLegendView to be scrollable, or adapted on 2 columns, but being able to set different height is also fine.
