Customise Colours in stackedplot

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

I solved it crudely using a tiledlayout with spacing set to none.

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 original question edited as that mistake was a typo, and not part of the issue at hand. Thank you for your intital responce none the less.

I did not know that indervidual lines had handles aswell, thank you very much for your time.

[Adam Danz]

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

[Tristan Deppe]

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

[Adam Danz]

Great question, @Tristan Deppe. This is the trouble with using undocumented methods.

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-')

% 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
    hold(ax(2),'on');  
    plot(ax(2),...,'r-')
% 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';

@Adam Danz I didn't understand your instruction, where should put ?

hold(ax(2),'on'); 
plot(ax(2),...,'r-')

[Adam Danz]

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

[Hugo Fortescue]

I was not able to get the desried results with stackedplot, but have recreated the same format using tiledlayout.

t = tiledlayout(4, 1)
t.TileSpacing = 'none';
t.Padding = 'loose';

a = nexttile;
    plot(A, 'k');
    set(a, 'XTickLabel',[], 'xtick', [], 'FontSize', 14);
    ylabel('(i)','rotation',0,'VerticalAlignment','middle', 'HorizontalAlignment', 'right');
b = nexttile;
    plot(B1, 'k');
    hold on
    plot(B2, '--r');
    plot(B3, '--r');
    set(b, 'XTickLabel',[], 'xtick', [], 'FontSize', 14);
    ylabel('(ii)','rotation',0,'VerticalAlignment','middle', 'HorizontalAlignment', 'right');
c = nexttile;
    plot(C, 'k');
    set(c, 'XTickLabel',[], 'xtick', [], 'FontSize', 14);
    ylabel('(iii)','rotation',0,'VerticalAlignment','middle', 'HorizontalAlignment', 'right');
d = nexttile;
    plot(D, 'k');
    set(d, 'FontSize', 14);
    ylabel('(iv)','rotation',0,'VerticalAlignment','middle', 'HorizontalAlignment', 'right');      
    xlabel('X Axis Lable');
    
han2 = axes(fig2,'visible','off'); 
han2.YLabel.Visible = 'on';
ylab = ylabel(han2,'Y Axis Lable');
set(han2, 'FontSize', 14)
ylab.Position(1) = -0.1; 
ylab.Position(2) = 0.5;

It is by no means a perfect solution, but replicates the desired reuslts well.

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.

[Lianne Wolsink]

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
