Hello,

I wanted to know if I can achieve interpolation of values within a heatmap. Is there any mechanism out-of-the-box?

Thank you very much.

Regards,
Sebastian

Hi Sebastian,

Thanks for your question and sorry for the late reply. Concerning interpolation of values, Heatmap 2D doesn’t have such capability for now. The reason being that it does all calculations on CPU, which is slow, so it would be even slower with interpolation.

We have plans to rewrite 2D Heatmap to use GPU, and it will provide such functionality. Unfortunately, we cannot tell you when it will be implemented, as we don’t have any precise dates yet.

Alternatively, you can use our 3D Heatmap which already has values interpolation implemented. Please refer to this example for more details: Uniform Orthogonal Heatmap .

Hope this helps! Please let us know if you have any questions,

Best regards,
Yuriy

Yuriy,

Thanks for the reply. I’ve been looking into this and have further questions.

I’m seeing nice interpolation when all data points have data. If I have incomplete data, is there a way that the heatmap can add “noice” to unset data points?

Please see attached example of a heatmap surface data.

I would like for the heatmap to interpolate the data values that are empty (by adding noise or other mechanism). Can I achieve this directly through the heatmap?

Thank you.

Best regards,
Sebastian
