I have an array that is long in one dimension and short in another, let's say 50 x 5000. Each of the 50 rows is a point in space and each of the 5000 columns is a time. I would like to plot isochrones as so:
X = 50;
T = 5000;
x = 0:X;
t = 0:T;
M = somefun(x,t);
However, I would like to plot many irregularly- (logarithmically?) spaced columns and would like to color them with increasing time and provide a corresponding colorbar. I can think of several ways to brute-force this, but I suspect that there is a simple way that I am missing. I envision something that looks like this:
Any help will be greatly appreciated.
