I am trying to plot the results of solving the transient heat equation. I want to use pdeplot to show the temperature distribution at a few different times. However, I want the color scale to be the same for each time, i.e. I want it to vary from 0 to 76. The different color scales currently can be misleading (see image)...

Here are the lines of code:

figure;
subplot(3,1,1)
pdeplot(model,"XYData",u(:,1),"Contour","on", "ColorMap","jet")
subplot(3,1,2)
pdeplot(model,"XYData",u(:,12),"Contour","on", "ColorMap","jet")
subplot(3,1,3)
pdeplot(model,"XYData",u(:,50),"Contour","on", "ColorMap","jet")

I have tried to update the axis' with:

axis([-inf inf -inf inf 0 76])

but this is not right. I'm not easily seeing from the pdeplot documentation how to do this... Any suggestions?

Thanks

Use clim for each subplot.

figure;
subplot(3,1,1)
pdeplot(model,"XYData",u(:,1),"Contour","on", "ColorMap","jet")
clim([0 76])
subplot(3,1,2)
pdeplot(model,"XYData",u(:,12),"Contour","on", "ColorMap","jet")
clim([0 76])
subplot(3,1,3)
pdeplot(model,"XYData",u(:,50),"Contour","on", "ColorMap","jet")
clim([0 76])
