Log axis on imagesc

I've plotted an image using imagesc:
figure;
imagesc([pmin pmax], [vmax vmin],flipud(result.^2))
xlabel('Period (s)','FontSize',20)
ylabel('Velocity (m.s^-^1)','FontSize',20)
set(gca,'ydir','normal')
and would like to make the x-axis logarithmic. If I just do set(gca, 'XScale','log') it changes the scale but not the image. How can I change the image and the scale? I've tried plotting with surf as well, but that's not producing what I want. My xscale values are 2:0.1980:101, so I'm not sure what the best way of plotting this is. Any suggestions are much appriciated!

I think what you want is to use surf with x and y set to your values.
surf(1:100,1:100,magic(100));
set(gca,'XScale','log');

If this isn't correct, could you attach your data in a zip file?

I'm not able to reproduce what you're describing (guessing at pmin, pmax)
surf(1:100,1:100,magic(100));
set(gca,'XScale','log');
view(2)
set(gca,'XTick',2:(pmax-pmin)/10:102,'XTicklabel',round(2:(pmax-pmin)/10:102))
