plotmatrix

Draw scatter plots

Syntax

• plotmatrix(X,Y)
  plotmatrix(...,'LineSpec')
  [H,AX,BigAx,P] = plotmatrix(...)
  

Description

plotmatrix(X,Y) scatter plots the columns of X against the columns of Y. If X is p-by-m and Y is p-by-n, plotmatrix produces an n-by-m matrix of axes. plotmatrix(Y) is the same as plotmatrix(Y,Y) except that the diagonal is replaced by hist(Y(:,i)).

plotmatrix(...,'LineSpec') uses a LineSpec to create the scatter plot. The default is '.'.

[H,AX,BigAx,P] = plotmatrix(...) returns a matrix of handles to the objects created in H, a matrix of handles to the individual subaxes in AX, a handle to a big (invisible) axes that frames the subaxes in BigAx, and a matrix of handles for the histogram plots in P. BigAx is left as the current axes so that a subsequent title, xlabel, or ylabel command is centered with respect to the matrix of axes.

Examples

Generate plots of random data.

• x = randn(50,3); y = x*[-1 2 1;2 0 1;1 -2 3;]';
  plotmatrix(y,'*r')
