Chart fails to initialise

Open ash-burns opened this issue 1 month ago • 11 comments

Describe the bug

Since v5.2.0 the chart can fail to initialise entirely when exceeding the default timeout. The easiest way to recreate this is to set browser's network throttling to a slow speed and watch as the highcharts chart never fires the chartInstance event. I would consider this a seriously breaking change as this behaviour does not exist in v5.1.0.

Expected behavior

No matter how long it takes to initialise, the highcharts must load the desired chart correctly and fire the chartInstance event once ready.

Steps required to recreate the problem in the demo:

  1. Slow down network speed
  2. Load highcharts graph
  3. Fails to ever display graph

Setup used

  • highcharts-angular v5.2.0
  • highcharts v12.4.0
