how can I fill between two plot lines from a matrix?

Have loaded in my data and wanting the area between the two lines to be filled in. Lines have different values, not just flipped values! Code is below, thanks in advance.

naturalised=load('naturalised.csv')

max=plot(naturalised(:,1),naturalised(:,3))

min=plot(naturalised(:,1),naturalised(:,4))

You did not post your data, so we can only guess what ‘naturalised’ is, although we can correctly assume that you are plotting columns of ‘naturalised’.

Try this:

figure
max=plot(naturalised(:,1),naturalised(:,3));
hold on
min=plot(naturalised(:,1),naturalised(:,4));
patch([max.XData, fliplr(min.XData)], [max.YData, fliplr(min.YData)], 'm')
hold off
grid

This worked with test data:

naturalised = [(0:20); zeros(1,21); 1+rand(1, 21); 3+rand(1,21)]';

It will probably work with your data as well.

thank you, worked perfectly!
