Error popover displayed when user tries to export (offline exporting) highcharts scatter chart as JPEG or PNG format inside Lightning components.

Here's the screenshot of the error popup:-

enter image description here

Error:

Failed to execute 'drawImage' on 'CanvasRenderingContext2D'

Exporting works fine with SVG as well as PDF. The issue exists when we do offline exporting as JPEG or PNG.

Can anyone help me out in this ?

This is a known feature gap in Locker Service. We have fixed it in winter 18 release. W-4063448 is the bug associated with the fix.

    So are you suggesting that we should wait till winter 18 release ? Or is there any quick workaround we could use. – Junaid P Khader Jul 26 '17 at 5:11
  • Hi @RaviJayaramappa Any workaround for this issue or waiting till Winter 18 release is the only option? – SE_User Sep 18 '17 at 12:02

    @SE_User There are no workarounds as of now. But the good news is that Winter 18 is being deployed to all productions instances in the coming weeks. All SandBox instances are already on Winter 18. – Ravi Jayaramappa Sep 18 '17 at 17:46
  • That sounds good. Thank you @RaviJayaramappa for the update! :) – SE_User Sep 18 '17 at 18:03
