Hi,
I feel sorry for the delay in responding to this post.
I am afraid that I am not able to reproduce the issue. Disabling the above properties should improve the performance of the Chart when there is a user interaction like mouse movement. Please find attached the simple sample which plots with 3000 bars.

Kindly try reproducing the issue with this sample and send it back to me so that it would be easier for me to find a better solution.
Regards,
Geetha
