How to hold colorbar in contourf plot

Hello everyone

I want to plot a contorf plot in logaritmic scale. first I want to plot in normal to provide colorbar, then hold the colorbar and scale the datas to log10 and plot again. this is the code:

contourf(a,b,c);

h = colorbar('YScale','log');

hold(h);

d = log10(c);

cla

contourf(a,b,d);

but the colorbar doesn't hold and when I re plot the the contourf, the colorbar is disappear, and if i plot the colorbar again, then it is shows the colorbar of new contourf which is wrong.

So, how can I plot the colorbar of the first contourf on the second plot of contourf? how can I hold or keep the colorbar? thanks.

I haven't tried this entirely, but instead of cla and replotting try

figure(1)

contourf(1,b,c)'

h = colorbar('YScale','log');

d = log10(c);

figure(2)

contourf(a,b,d)

a = get(1,'children');

copyobj(a(1),2);

This is a crude reparenting of the colorbar from the original figure to the new one.
