Hi, I am trying to understand image plot. When I run this example
x = [1 5];
y = [1 5];
C = [0 2 4 6; 8 10 12 14; 16 18 20 22];
imagesc(x,y,C)
I get the figure (attached here).
In Y axis its comes in descending order. I want to get it in Ascending order. How can I control the axis range?

h1 = axes ;
imagesc(x,y,C) ;
