How do I make heatmap axes order from bottom-top?

I am struggling with making heatmap order from bottom to top.

Snapshot is what I have currently, but I want to flip the plot order.

Thank you

x = magic(10);
figure
imagesc(x) % notice the y-axis goes from 10-1 from bottom to top
set(gca,'YDir','normal') % now it is reversed!
