[Ondrej Svoboda]

Hi,

I have ColumnSeries with 4 columns and I want to show them all in the legend, not just the series label. (same like it is for pie series) Is there a way how to do it?

Thanks

Hi,

one more requirement: I need to bind legend labels to different property in my data source than I have for primary axis. Possible?

For example:

On primary axis I want to have item codes: 1,2,3,4,... but in the legend I need item description: BMW, Jaguar, Toyota, etc.

Thanks!

Never mind, I've been able to solve this myself using ChartLegend.ItemTemplate.

Thanks anyway!
