Chart problem

[Anikin Victor]

I use the StackedBarSeries to display data.While drawing some of the columns are overwritten by other columns. Tell me how to fix this?

Hi Anikin,

This is a common problem with stacked bar series - when there are some bars that are close together - there is no space for all labels. You can try to enable the smart labels and see how that goes:

<telerik:ChartArea SmartLabelsEnabled="true" />

 
Another solution is for you to show only one label per stack - instead of three labels, show only one - with the sum in it. Let us know if you need further assistance.

All the best,
