How to show values on heatmap belonging to a different dataset.

14 views (last 30 days)
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

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
You can of course easily change the grid dimensions if you want something more meaningful on the axes.
