Hi, Our application need a semilog graph. I acheived this by using strip lines. But When Zooming the graph, the strip lines are looking like bands.so i changed my design to draw the lines instead of strips in ChartAreaPaint(I got this solution from Syncfusion forums.Thanks to Syncfusion Support team). But the following are the problems that i''m facing in implemntation. Please suugest me a solution. Here i attached the sample code which we are using in our application. I got an error in graph when i Zoomed it continuously. How to avoid this error? or how to set Range for Zooming? When i''m Zooming the chart, lines are drawn outside the chart. how can we avoid this? Thanks, Sriram

Hi Sriram, Thanks for bringing these issues to our attention and I am able to reproduce the issue ( When i''m zooming the chart,lines are drawn outside the chart). I have logged bug report on this regard and will update you as soon as the fix is available. The following code snippet illustrates to set Zooming Range. this.chartControl1.EnableXZooming = true; this.chartControl1.PrimaryXAxis.ZoomedRange.Min=0; this.chartControl1.PrimaryXAxis.ZoomedRange.Max=10; this.chartControl1.PrimaryXAxis.ZoomedRange.Interval=2; I am afraid that I am not able to reproduce the issue while zooming out the graph(i.e Continuously - sign). Could you please let me know the Essential Studio version you are using? Please take a look at the sample attached. Let me know i fthis helps. Regards, Ramesh.

Hi Ramesh, I''m using the version 4.1.0.50. In the above sample if i''m Zooming out continuously the application is breaking and giving "Overflow" exception.
