Overlaying two contour plots on same axis

I am trying to plots two contours on top of each other
Code is below, cannot work out why it is not working.
figure(1)
[c1,h1]=contourf(long1,lat1,squeeze(asal(:,:,36))',[34.6:0.01:34.9],'LineColor','none')
cmocean('balance')
colorbar
hold on
[c2,h2]=contour(long1,lat1,squeeze(pot_dens(:,:,36))',[26.80:.01:27.0],'k--')
clabel(c2,h2)
I have attached the different plots seperately, and the combined result.
I want just the sal plot as is, with the potential density contours overlaid
Thanks in advance

Hi James,
As per my understanding you are looking for plotting two contour plots on the same axis.
Here is the reference code where two contour plots are overlaid on the same axis.
%%code starts here
Z1 = peaks; %Sample data 1
Z2 = peaks.^2; %Sample data 2
hold on
contourf(Z1,'-r');
contour(Z2,'--k');
colormap('map')
axis equal
%%code ends here
The plot for the above code with the sample data where the two counter plots are overlaid is shown below
The output figure shows both Z1 and Z2 are contour plotted on the same axis, with Z1 being filled 2D plot and Z2 with the contour plot.

Contour plots can be colour mapped using the “colormap”. For more information on colour mapping the contour plots, please check here
