As you have not given any specific data set. I am taking a random data to give you an example.

Example 1

Just plot all three lines subsequently.

col={'r','b','k'}
for kk=1:3
    aa=spline((0:15),randi(10,1,16),(0:0.1:15))
    x=randi(100,1,1);
    plot((x:0.1:x+15),aa,col{kk})
    hold on
end
legend({'Line 1','Line 2','Line 3'})

Don't worry if you don't understand the third and fourth line. It's just the random data.

Example 2

If you want to skip using the loop, you can plot using cellfun too. The following loop is just to create the random data set. If you have the dataset, just put them in a cell.

col={'r','b','k'}
for kk=1:3
    YY{kk}=spline((0:15),randi(10,1,16),(0:0.1:15))
    x=randi(10,1,1);
    XX{kk}=(x:0.1:x+15);
end
hold on
cellfun(@(x,y,z) plot(x,y,z),XX,YY,col,'uni',0)
legend({'Line 1','Line 2','Line 3'})

My curve details are as follows.

1st curve (400cm to 1030cm in x-axis). For every value in x axis there is a corresponding value in y-axis. totally 721 samples for 1st curve.

2nd curve (805cm to 1060cm in x-axis).For every value in x axis there is a corresponding value in y-axis. totally 665 samples for 2nd curve.

3rd curve (345cm to 1750cm in x-axis).For every value in x axis there is a corresponding value in y-axis. totally 900 samples for 3rd curve.

[ANKUR KUMAR]

Its just the random data. Store X values in XX and y values in YY and run this one.

    col={'k','b','r'}
    XX={linspace(400,1030,721),linspace(805,1060,665),linspace(345,1750,900)}
    YY={randi(10,1,721),randi(10,1,665),randi(10,1,900)}
    hold on 
    cellfun(@(x,y,z) plot(x,y,z),XX,YY,col,'uni',0)

If this doesn't help you, then provide us the data, so that we can help you in a bit more effective manner.

I am getting the following error

Error using linspace Too many input arguments

[ANKUR KUMAR]

Cross check you prog. I have run twice the above prog.
