This one appears to get fixed by #20449.

See the demo with the fix applied.

It seems that it's still failing for datasets above 1000 points, could you guys confirm?

For more than 1000 points, the chart is not showing up.

Any update on this? The suggested workaround is still failing for more than 1000 points.

Hi @reydoblas! The ticket is prioritized in our backlog and as you can see it is classified as a blocker. When the work starts you'll get the notifications here.

Internal note

... and here's the reason our visual tests didn't catch it:

highcharts/samples/highcharts/demo/heatmap-canvas/demo.js

Line 84 in 1da9749

turboThreshold: Number.MAX_VALUE // #3404, remove after 4.0.5 release

If we comment out turboThreshold in our demo, it fails too. The fixing PR should remove that line.

@hubertkozik Any update on this? There's a new release version 11.4.0 but the fix for this is not yet there. I can see

#Fixed #20433, boosted scatter chart did not work without axis min/max-options.

as part of the changelog but it still don't fix the heatmap series not rendering in boost mode.
