PA/TM1 Web blurred diagram

[McSash]

Hi all,

I'am currently facing an issue where Excel diagrams are blurred in PA Web.
The axis legend (Jan, Feb,..) is written in normal Excel cells and perfectly clear.
The chart bars as well as the data labels aren't.

Does anyone know the cause or a workaround to fix this behaviour?

Edit: I'm using PA 2.0

Thanks in advance
