Hi,
I have a cwt figure plotted with pcolor. I can open the property inspector on the figure and manually change the "Scale" property to log. I would expect the command to set the y axis to log scale be something along the lines of;
figure()
h = pcolor(1:size(wt,2),f,db(abs(wt)));
h.EdgeColor = 'none';
h.YAxis.Scale = 'log';
and https://uk.mathworks.com/help/matlab/ref/matlab.graphics.axis.decorator.numericruler-properties.html seems to agree with me, however I get an error that "Scale" is not a property class for primitive surfaces. Fair enough, I am guessing the name in the propery inspector is just a generic placeholder, could someone point me in the correct direction for what the correct property name is for Yaxis scale with pcolor?

Ran in:
Try this:
C =[1 2 3;4 5 6; 7 8 9];
pcolor(C);
ax=gca;
ax.YScale='log';
