Hey guys, please, could someone help me with this. I am trying to plot a 2D pcolor figure as longitude X depth, and water density as colors. I also want to add contours, just at specific color levels, but I just was able to do it with same number of colors and contour levels, this way:
contourf(lons,zs2,dens,20,'k');
ylabel('Depth (m)','fontsize',6,'fontweight','b')
xlabel('Longitude','fontsize',4,'fontweight','b')
in the contourf, 20 is the number of levels. But actually I want specific levels, e.g., [-0.3 0 0.3]. The function help says it can be a vector, but when I try, I get an error saying it must be a matrix the same size of longitude X depth. Then, I imagine I need to build a matrix containing only the values correcponding to [-0.3 0 0.3], and the remaning as NaNs. Am I correct? If yes, please, how can I do that? Or if I am wrong, there is another way to do what I want? data attached!
Thank you very much in advance.
