Customise Colours in stackedplot
显示 更早的评论
I have this figure here, and I need to change the line style of the 2 horizontal images in (b) online. The command :
s.LineProperties(2).Color = 'r'
changes all 3 lines, and I am not sure how to change only a single one.
Thanks!

Please share the code for quick fix, if possible

In the original version of your question before it was edited, the color assignment included a linstyle ('--r').
You have to set them separately. These settings will be applied to all lines within the selected axes.
data = sin(linspace(-pi,pi,100)'.*(.5:.5:2.5));
s = stackedplot(data);
s.LineProperties(2).Color = 'r';
s.LineProperties(2).LineStyle = '--';
Working with multiple lines per axes
If there are multiple lines in a pair of stacked axes and you only want to change the color of one line, get the line handles from the axes handles.
% Create table
data = sin(linspace(-pi,pi,100)'.*(.5:.5:3.5));
T = array2table(data,'VariableNames',{'A' 'B' 'C' 'D' 'E' 'F' 'G'});
% Plot 3 lines on the 2nd axes from the top
figure()
Vars = {'A' {'B' 'C' 'D'} 'E' 'F' 'G'};
S = stackedplot(T,Vars,'-k');
S.AxesProperties(2).LegendVisible = 'off';
% Get axes handles
ax = flip(findobj(S.NodeChildren, 'Type','Axes')); % order: top to bottom
% Get line handles in axes #2
lines = flip(ax(2).Children); % order: top to bottom
% Color line #2 in selected axes
drawnow(); pause(.05) % required
lines(2).Color = 'r';

The NodeChildren property is undocumented and that's how I got the individual axis handles. The line objects are children of the axes handles.

Any ideas why the line colors all revert to black if I resize the figure window or try and save/print the figure?

A workaround is to merely add the line to the axes after creating the stackedplot. Get "ax" from my answer, then,
hold(ax(2),'on');
plot(ax(2),...,'r-')

@Adam Danz I didn't understand your instruction, where should put ?
hold(ax(2),'on');
plot(ax(2),...,'r-')

This answer does not show how to add a line to an axes. It shows how to change the color of an existing line.

I just noticed that your 2nd axes has 3 lines - they are difficult to see in the embedded image in your question. I've updated my answer to show how to set the color of a single line in stackedaxes that contains multiple lines per axes.

Using stackedplot, the color of one line within an axis containing multiple lines can be changed using this code:
a = stackedplot(table,vars);
a.LineProperties(2).Color = [0 0 0
1 0 0]; % changes colors of lines in axis 2 to black for line 1 and red for line 2
