2D plot with 3 axis and 3 column data

I have 3 column data. I plot 2D 3 axis graph in Excel. I want the same also with colours and labels on Matlab. It is attached as graph name. Can you help me please?

I have no idea which column is which curve.

Try this:

[D,T,R] = xlsread('Kitap3.xlsx');
Q1 = D(1:15,:);

time = linspace(0, size(D,1), size(D,1));

figure
yyaxis left
plot(time, D(:,1))
hold on
plot(time, D(:,2))

yyaxis right
plot(time, D(:,3))
hold off

Experiment with the column assignments to get the result you want.

See the documentation on yyaxis for details.

@star strider thank you for your answer. Code is working very well but I don't want one of line as a dashed line. How can I fix this.

As always, my pleasure!

For yyaxis plots, the only way is to make them differnt colours.

Since I assume you are referring to the yyaxis left plot, try this:

yyaxis left
plot(time, D(:,1) ,'-b')
hold on
plot(time, D(:,2), '-g')

The rest of the code is unchanged.

@star strider. Thank you very much, and this is my last question I promise :) How can I add a label on right yy axis?

As always, my pleasure.

Try this:

figure
yyaxis left
plot(time, D(:,1))
hold on
plot(time, D(:,2))
hold off
ylabel('Left y-Axis')

yyaxis right
plot(time, D(:,3))
ylabel('Right y-Axis')
xlabel('Time')

This labels both of them, and the x-axis. Delete the ones you do not need.
