problem with zoomingIn while viewing printpreview

hai ,
In my chart control , to view strip lines with same width in case of zooming also , i am continuously drawing these lines in chart area paint.here , i am printing three chart controls in a single print.

The problem is when i zoomed chart control after that, if i am trying to open printpreview ,the application is getting crashed.
Expecting very quick response from you,

Thanking you,
sharada..

Hi Sharada,

Sorry for the delayed response.

I was able to reproduce the mentioned issue.

To avoid the crash do the following :

1) Change the ChartSeriesType from scatter to spline.
2) Avoid the code which reduces the spline tension.

Please have a look at the attached sample which helps you to print the Zoomed chart without any crash.

Thank you for your continued interest in Syncfusion products.
