HeatMap - WebGL not supported on Device

[Anduve11]

I'm trying to create a heatmap and I'm getting an error that says, "Sorry, unable to render. This visual requires WebGL, which is not supported by this device."

How do I enable WebGL on my device?

I can see how I enable it on my browser like Chrome or Firefox, but I don't see anything about enabling it on a device.  Any help or advice?

I encountered this exact issue in PBI Desktop, despite knowing that WebGL 1 was enabled on my device (you can check for yourself here: http://webglreport.com/ ). The steps below got things working, but I'm not sure I would trust this in a production enivronment just yet. Either way, hopefully this will help someone.

1. Instead of using PBI Desktop, I accessed my report using the PBI Service and added the heatmap visualization through the marketplace. This time, the visualization did not throw the WebGL error and I was able to add data to it, make changes, etc.

2. Then I went to save my report, but it threw an error saying that it failed to save any changes. I tried twice more but as long as the heatmap visual was in the report, it would not save.

3. I then re-opened PBI Desktop, added the visual from the marketplace, and bam, it worked. Now it works in both PBI Desktop and PBI Service.

Again, I don't fully trust it yet. Be cautious unless your use case is not critical and you have patient users 🙂

Hi @Anduve11,

Sorry for the delay.

Unfortunately, here is a limitation for HeatMap that this visual requires WebGL, which however may not be supported by every device. In case of seeing the "not-supported error", you may need to try a different machine. Sorry about the limitation.

You could find the limitation in this blog.

Best Regards,

I'm having the same problem, and it was working perfectly within a few days.
I do not know what's changed to make it happen.

I do not know what has changed to stop working.
