Thanx for providing me the solution. It is very much useful for me, Now i have one more query about stacked bar chart. Actually i am new to telerik charts. I have 3 series named Space limit used, space limit projected, space limit total and i am providing it to my chart like this.
ChartSeries cs = new ChartSeries();
ChartSeries cs1 = new ChartSeries();
ChartSeries cs2 = new ChartSeries();
cs.AddItem(GetSpaceLimitUsed(), "Space Limit Used");
cs.Name = "Used";
cs1.AddItem(4000, "Space Limit Projected");
cs1.Name = "Projected";
cs2.AddItem(6000, "Space Limit Total");
cs2.Name = "Total";
It will draw the chart image as three bars seperately ,but i want it to be drawn three bars one on another showing one stacked bar.
