is there any way to get charts etc. to render at a higher resolution so they look better when using a retina display?
Note, there is a property available in the latest SRs for 13.2 to increase the rendering resolution if you are on a retina device.
You can set pixelScalingRatio to 2 on the chart to increase the resolution.

Hi,
Would it be possible that you supplied a simple example of how to do this ? We are struggeling with the problem mentioned above. The charts looks less crisp then we would like them too.
One option you have is to set the chart to be larger in width and height pixel wise, but then scale it down using css width and height back to the normal size that you desired. The iPad is mapping HTML sizes in such a way that when you request someone of certain pixel dimensions on a non-retina screen, it will use the same pixel dimensions on a retina screen. This results in things looking blurry as they have essentially been rendered at a smaller size and then scaled up to the higher DPI. There is nothing built into the chart currently that will let it detect the higher DPI and render more pixels, but, if you can detect the higher DPI, you could make the chart render more pixels by setting its size to be physically larger, but scaling its container back down to the same render dimensions as before. Make sense?
Hello barney,
I am just following up to see if you need any assistance with this matter.
Based on my understanding, you can set the windowScaleVertical and windowScaleHorizontal property. Refer to the “OPTIONS” tab on the link below that will give more details on this:

I hope this helps.
