How can overlay two contour plot in a subplot?

조회 수: 33 (최근 30일)
Hello,
I am trying to plot and overlay two contour plots in the same figure but with some specifications. Both plots share the same x and y coordinates (and scales).
1. This two contour plot must be in a subplot of 2x1.
subplot(2,1,1)
2. The first contour plot (background) must be with lines and filled with his own colorbar.
Z1 = peaks;
contourf(Z1,'--')
colorbar
axis equal
3. The second contour plot (foreground) must overlay the first one and NOT be filled, just lines without colorbar.
Z2 = peaks.^2;
contour(Z2,'-')
axis equal
I am not using my real data for simplicity. How can we overlay this plots? Without destroying the first plot (preserve colors and colorbar). I reviewed these links but when I use the subplot function it does not work.
Thanks in advance for the answers.

I found this solution
Z1 = peaks;
Z2 = peaks.^2;
ax = subplot(2,1,1);
hold on
contourf(Z1,'--')
colorLim = ax.CLim;
contour(Z2,'-k')
ax.CLim = colorLim;
colorbar
axis equal
First, we saved the color limits CLim. Then, we plot the second contour plot and set the CLim from the previous one.
