performance issue for using calculated measures in box chart elements

[Sai_Mohan]

I have used box chart and variable extension (buttons).

In box chart elements, i have calculated  median, 25% quartile etc..

Everything is calculated measure inside it and i couldn't change that because i need values dynamically.

if i click button,  it is loading more then 5 sec to display the box chart.

Is there any other idea to make performance good without changing elements in box chart? 

Regards,

Sai.
