Hello :)

How can I add contours (at 0.05, 0.075, 0.1 degrees) instead of filled colours in this pcolor plot?

Thank you in advance!

Code I used for the figure is below

cm1 = brewermap(40,'RdPu');
cm1(cm1>1) = 1;
cm1(cm1<0) = 0;
LONLIMS=[-16 7.8];
LATLIMS=[47 62];
figure
m_proj('miller','lon',LONLIMS,'lat',LATLIMS);
m_pcolor(lont(1:end-1),latt(1:end-1),mean(tdh,3)')
shading flat
caxis([0.05 0.1])
colormap(cm1)
m_grid('fontsize',10);
m_gshhs_f ('patch',[.8 .8 .8],'edgecolor',[.1 .1 .1]);
cb = colorbar;
cb.Label.String = 'Horizontal Temperature gradient (\circC)';
