I created a contour map with some irregular data inputs. Plotly neatly interpolates missing data and create a nice image.

Is it possible to export/access the raw data for further processing?

For example let say my input data is at columns [0, 1.2, 2, 3.4, 4] and i want to export the values at [0, 1, 2, 3, 4] instead. Or export more detailed data [0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4].

Hi @jerometremblay I don’t think you can export the interpolated version of your data, it is probably done in plotly.js directly in the GPU. You can however use Python libraries like `scipy.interpolate` for this kind of tasks 🙂

Thank you for the hint. The main goal is to evaluate the plotly.js and see how it compares to our previous system.

I understood that the interpolation itself is not done by the contour map but by the heatmap, and managed to place breakpoints inside heatmap/plot.js and observe see what is going on.

I can recover pixel data, but not yet data points. I suppose i’ll figure it out. 🙂
