Indicate name of filled areas inside area plot - Matlab?
Oliver Amundsen
It's difficult to identify in this area plot each one of the many filled areas by just looking at the legend (it's like 16!).
So, I was wondering if there's a way to place some sort of labels (with a pointer perhaps?) inside the plot that clearly identifies each filled areas?
Thanks!

Here is an alternative using annotation objects and the textarrow option, which displays text along with an arrow. This could be useful to you to point in narrow regions where text would hide data.
For example:
clear
clc
close all
x = 1:128;
%// Plot data
figure
hAxes1 = axes('Position',[.1 .1 .6 .8]);
image(x.');
axis off
colormap(jet(128))
%// Define labels
ColorLabels = {'Red';'Orange';'Green';'Blue';'More blue'};
%// Define starting and ending x and y positions
xstart = .8;
xend = .6;
ystart = linspace(.1,.8,numel(ColorLabels));
yend = linspace(.15,.8,numel(ColorLabels));
for k = 1:numel(ColorLabels)
annotation('textarrow', [xstart xend],[ystart(k) yend(k)],...
'String', ColorLabels{k});
end
gives the following output:
