Hi,

It looks like the anti-alias is off. We do not know what's causing it yet, we will need to debug into the code to find out and update here again when we have additional information.

For high quality chart, you may want to look into a SVG based chart solution. The above chart is canvas based. Internally canvas is represented by a bitmap and while it can look good on the screen, the bitmap is limited to screen resolution, which would cause quality artifacts when you zoom in or print it out (since printer has a much higher resolution than screen). On the other hand, SVG is a vector format, so you can zoom in without losing any quality at all.

Thanks!

Yes. This will be addressed in our up coming release, which should be out very soon. We were waiting for the release to be posted before updating you again.

Hi,

This is just to let you know that we have posted the new build. You can download it from our download page. Please take a look and let us know how it goes.

Thanks!

Great. Thanks for confirming the fix!
