For example:
load clownimagesc(X)colormap(map)Instead of the y-axis increasing from top to bottom, I would like to have it decreasing from top to bottom.

You can manually set the position of ticks on the colorbar axis by using the CAXIS function to set the color axis limits, and setting the 'YLim' and 'YTick' properties of the colorbar, as shown in the following example:
A = ceil(5*rand(5,7));imagesc(A);numcolors = 5;colormap(jet(numcolors));caxis([1 numcolors]);cbarHandle = colorbar('YTick',...[1+0.5*(numcolors-1)/numcolors:(numcolors-1)/numcolors:numcolors],...'YTickLabel',int2str([1:numcolors]'), 'YLim', [1 numcolors]);Do you mean like with axis xy?
[x, y] = meshgrid(1:16, 1:7)eta = uint8(rescale(sqrt(x.^2 + y.^2), 0, 255));T=[360, 660];p=[64, 250];subplot(2, 1, 1);imagesc(T,p,eta)axis('on', 'image');subplot(2, 1, 2);imagesc(T,p,eta)axis('on', 'image');axis xy
