I have a torque and RPM dataset and i am plotting %torque using heatmap. but the value(text) in each grid of %torque heatmap i want to display some other data set number. The reason i am doing this is so that in the background i can see %torque heatmap and see the color and on top of it will have the value of the other data set which me help me compare the value. Can this be done in matlab??

Thanks

Hey! Jonas. really appreciate your help but unfortunately i wont be able to upload any data due to confidentiality concerns. However i am dealing with two matrix both of the order of 13 rows and 25 columns. you can prob make two separate rand matrix of that dimension and share your code. I can look into it and share my results with you. let me know if you would need more info about the data.

在 MATLAB Online 中打开

Here's an example using imagesc and text

% Grid
[X,Y]=meshgrid(1:10,1:10);
% Two data sets to compare
A=rand(10,10);
B=-10.*rand(10,10);
% Plot grid
figure;
h=imagesc(X(:),Y(:),A)
% Text
txt=sprintfc('%.1f',B(:))
text(X(:),Y(:),txt,'horizontalalignment','center','verticalalignment','middle')
colorbar
