Hello Together,
i have a rather specific problem:
I have a set of measurement-Data in XYZ-Format that i want to plot as a Heatmap. The Y-Axis is equaly spaced. The X-Axis-Values, however, are not, as they were also measured individually together with the corresponding Z-Value.
Converting now to a matrix for heatmap plotting via gridding is not sufficient for me as it falsifies the result.
Is there a way how i can plot the Heatmap, while for each Y-Value Row a different X-Spacing is used? Especially Contour smoothing must not be enabled.
For clarity, here is a minimal example of the data arrangement:
X Y Z
----------------------------------
-1 1 10
0 1 11
1 1 12
-0.9 0 11
0.1 0 11
0.9 0 10
-1.1 -1 9
0 -1 12
1.1 -1 13
I was able to successfully plot it the way i need it in Matlab via a loop
for i=(each row of Y)
imagesc(X(i,:), Y(i), Z(i,:))
end
so basically many stacked heatmap plots in one figure
Hope i could clarify the issue and that someone can help me :)
Best Regards,
Scotty3007

It could be done in the upcoming Origin 2024 using the X-function to Plot multiple sheets into one heatmap. Please watch the attached video for the steps.

I see, thank you already for your help.
Is there maybe also a way to accelerate this? Many measurements have to be evaluated this way and the Y-Axis consist of over hundred values... |

You can make such heatmap in Origin. But you need to make separate heatmp for each y, then merge them together. Please find the attached project file.

Here is what Matlab produces |

Could you attach a picture showing the graph generated by the MatLab code? Thank you.
