Plotting multiple 2D metrices

Hello.

I have two 2D metrices of different size

a = 2 x 375

b = 2 x 500

All data is between -0.5 to +0.5 in both X & Y Axis.

How to plot these data on the same Y vs X plot ? AND

How to plot these data against the number of iterations (normalized from 0) on the same plot?

As the data has same limit -0.5 to +0.5 you shall get the same Y-axis..why worried? Can't you use plot?

I tried but it didn't work. So my data looks like below. I am new to matlab, so i tried using plot (metrics1, metric2) and it was weired.

Two options:

% If each matrix has two curves 
figure
plot(A')
hold on
plot(B')
% If each matrix has (x,y) coordinates
figure
plot(A(1,:),A(2,:))
plot(B(1,:),B(2,:))

If not this you are expecting. Share your data.

Thanks Bro...that worked for first part!

How to do second part - plot these data against the number of iterations (normalized from 0) on the same plot?

That depends on how your code is. Two options.

1. USe hold on and plot inside the loop.
2. Save the entire data into a matrix and plot after the loop.

Thank you! That worked.

Thats good...Thank you accepting/voting answer. :)

By the way....current plot i am getting like this where axis are at bottom.

Is it possible to have something like below showing in 4 quadrants?
