@afreay,
It seems like you are performing zooming / panning with the help of slider. When you export the chart, the chart exports only the zoomed region. However you can set axis range to null, call exportChart method and reset axis range back to achieve your requirements. Please take a look at this JSFiddle for an example on same.
If this doesn’t solve the issue, kindly create JSFiddle with your use-case and share it with us so that we can look into the code, understand the scenario better and help you resolve.
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 many a time we can just edit your code to fix the issue right away.
