@keval-panchal,
exportChart method exports the entire chart, irrespective of whether the chart is within the viewport or not.
Can you kindly create JSFiddle with your use-case, so that we can look into the code / chart-options that you are using, understand the scenario better & help you out?
From what we have observed, sometimes things get delayed mostly when we are not able to reproduce the issue or not able to understand the exact requirements or the solution that we provide may not work properly due to the variation in chart-options being used by you and us.
Having a JSFiddle helps us in figuring out the issue and suggesting an appropriate solution accordingly.
