# 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!

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

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.
