Subplot a matrix within a single Graph

Hi,

    I have a matrix with four columns and 40 rows.  I want to plot these entries in a single plot with the first column in the upper left corner, the second in upper right left corner, third column in lower left corner, and fourth column in lower right corner of a single graph. 

    Can someone give a tip or code snippet?  

    Thanks!

It is not clear, how you want to draw columns in corners. A small example would be helpful. Does the tag "subplot" contain the necessary information? Could you show us, what you have tried so far and which problems occurred?

Hi,

Yes, you are right.  It was not clear.  

   I have a matrix whose columns represent four sets of "y" data.  I want to plot the column "y" data all in the same plot, but divide the plot into quadrants, each quadrant being assigned to one of the columns of "y" data.  The "x" data is the same for all.

For some random data of 40 rows, 4 columns, this plots a line plot

data = rand(40,4);

for i = 1:size(data,2)
    subplot(2,2,i)
    plot(data(:,i))
end

To plot only the points (no lines connecting them), use instead:

plot(data(:,1),'.')
