SSRS 2008 R2 Charts cropped and blurry

I hope anybody can help me with this. When I insert a chart into a new report (SSRS 2008 R2) in Visual Studio preview everything looks fine and sharp. But when I deploy and open the same report within the browser (IE 9 & Firefox) the chart is blurry and cut off on the right hand side as well as at the bottom. Finally, when I print the report everything is fine again.

I have included a screenshot

to better explain what I mean. Would be grateful for 开发者_C百科any hint on this problem!

Thanks a lot!

It may be related to image resolution. This website explains it:

Most monitors have a resolution in the range of 72 to 96 dpi (so I’ve been told), where as an image should be at least 150 dpi (dots per inch) in order to print with any clarity. [...] Higher resolution images look very blurry and pixilated when displayed on-screen but should print very nicely.

Perhaps reporting services is rendering the image at a resolution suitable for printing, and then scaling/cropping it to make it fit on the screen?
