Hi @nswamy14,

When I translate the heatmap (in X/Y directions), the heatmap disappears. I.e. the whole dive beomes white again.

It looks to me that the values arrive correctly:

Do you have any idea what could cause this?

Thanks! Bart

Hi @bartbutenaers,

Is it possible to share an env instance to reproduce the issue? It will help in debugging. Or share the snapshot of values configured for params: - height, width, devicePixel ratio, size, intensity, zoom, angle, opacity, max, min.

Thanks, Nswamy

Hi @nswamy14,

Did some further debugging myself, and at the end it appeared that the issue was in my own code: Seems I had forgotten to add a break in the "setTranslate" switch-case:

So immediately afterwards, the heatmap was zoomed (away). Sorry for the noise!!!
