Thread Subject: Plot 2D matrix with color gradient

Is it possible to plot a matrix with plot() that uses a color gradient to distinguish
between results?

I have a matrix of 200 columns x 300 rows where each column is a separate
simulation run and each row is a timepoint. This matrix is sorted by the sum of
each column where the least sums are first.

If I use plot(results_matrix) I get a 2d plot with 200 blue lines. I'd like to
generate a plot where the line from the first sorted column is blue and the last
sorted column is red. The lines in between use a color gradient between blue
and red just like the mesh() colorbar.

Any ideas?


Thanks!!

This might help:

  If you do not specify a color when plotting more than one line, plot
  automatically cycles through the colors in the order specified by the
  current axes ColorOrder property.
