I am plotting probability plots, but I want different colors for different data. All data are of different size ?

figure;

probplot('lognormal', Loadingtime_4);
hold on;
probplot('lognormal', Loadingtime_5);
hold on;
probplot('lognormal', Loadingtime_6);
xlabel('Loading Duration (secs)');
set(gca, 'XScale', 'log');  % Set the x-axis to use a logarithmic scale
xticks([10 50 100 500 1000 10000]);
xticklabels({'10', '50','100', '500', '1000', '10000'});
grid on;
legend('Lognormal Distribution','Data Drift 4,5 & 6','Location','southeast')
title('Lognormal')

https://www.mathworks.com/help/stats/probplot.html#bu27cw3-1 is an example that shows adding a line to a probplot(), and one of the steps it shows is changing the color

h = probplot(gca,t,p);
h.Color = 'r';

You can use that same technique to give different colors to your different probplot()

[Muhammad Tariq]

That does not solve the issue. I want something like this. Where each probplot is shown with different color and line.

But the plots are of different colors automatically -

%Using Random data
figure;
p1 = probplot('lognormal', randi(1000,1,100));
hold on;
p2 = probplot('lognormal', randi(100,1,100));
hold on;
p3 = probplot('lognormal', randi(500,1,100));
xlabel('Loading Duration (secs)');
set(gca, 'XScale', 'log');  % Set the x-axis to use a logarithmic scale
xticks([10 50 100 500 1000 10000]);
xticklabels({'10', '50','100', '500', '1000', '10000'});
grid on;
%legend('Lognormal Distribution','Data Drift 4,5 & 6','Location','southeast')

%color the function lines
p1(2).Color = p1(1).Color;
p2(2).Color = p2(1).Color;
p3(2).Color = p3(1).Color;

xlabel('Loading Duration (secs)');
set(gca, 'XScale', 'log');  % Set the x-axis to use a logarithmic scale
xticks([10 50 100 500 1000 10000]);

Thankyou so much Walter!

[Muhammad Tariq]

Thankyou Dyuman Joshi!

[Muhammad Tariq]

The only problem is that when I do it on my matlab it still gives the same color for all. I don't know what is the problem

%Using Random data

figure;

p1 = probplot('lognormal', randi(1000,1,100));

hold on;

p2 = probplot('lognormal', randi(100,1,100));

hold on;

p3 = probplot('lognormal', randi(500,1,100));

%color the function lines

p1(2).Color = p1(1).Color;

p2(2).Color = p2(1).Color;

p3(2).Color = p3(1).Color;

xlabel('Loading Duration (secs)');

set(gca, 'XScale', 'log'); % Set the x-axis to use a logarithmic scale

xticks([10 50 100 500 1000 10000]);

xticklabels({'10', '50','100', '500', '1000', '10000'});

grid on;

I needed to change it to this and now it works
