Hi,
I have three arrays, each 1X106 corresponding to the max., min., and mean values of a dataset.
See attached image. I would lie to be able to shade the area between the two dotted blue lines (the max. and min. values).
Any help would be greatly appreciated,
Thanks in advance! Star Strider on 4 Aug 2022
It would help to have the data.
This is straightforward using the patch function —
x = linspace(0, 110).'; % Entire Code Assumes Column Vectors
y1 = randn(size(x))/100 + 0.1;
y1d = 0.01*[-1 1] + y1;
y2 = randn(size(x))/100 + 0.01;
y2d = 0.01*[-1 1] + y2;
figure
plot(x, y1, '-b')
hold on
plot(x, y2, '-r')
patch([x; flip(x)], [y1d(:,1); flip(y1d(:,2))], 'b', 'EdgeColor','b', 'LineStyle','--', 'FaceAlpha',0.25)
patch([x; flip(x)], [y2d(:,1); flip(y2d(:,2))], 'r', 'EdgeColor','r', 'LineStyle','--', 'FaceAlpha',0.25)
hold off Make appropriate changes to get the result you want.
