Hello everyone, I have two plots like this:
plot(OBS,'Color','#007aa5')
hold on
plot(Modeled,'Color','#ff55a3')
xlabel('time step')
Now I want to illustrate the difference between these two plots by shade like the following example:
Where plot 2 is less than plot1, the difference determines by yellow sahde and where plot 2 is greater than plot1difference determine using green shade.
I attached my datasets,
Thank you in advance

LD1 = load('OBS[1].mat');
OBS = rmmissing(LD1.OBS);
LD2 = load('Modeled[1].mat');
Modeled = rmmissing(LD2.Modeled);
x = 1:numel(OBS);
figure
plot(OBS,'Color','#007aa5')
hold on
plot(Modeled,'Color','#ff55a3')
patch([x(:); flip(x(:))], [OBS; flip(Modeled)], 'b', 'FaceAlpha',0.25, 'EdgeColor','none')
xlabel('time step')
xlim([min(x) max(x)])
I am not certain what the ‘y’ axis is supposed to be. If the intent is that in increases from the top to the bottom (instead of the default shown here),. provide the appropriate axis tick values, then add:
set(gca, 'YDir','reverse')
.
