contour AND plot(,,'o')

[Daniel Heiserer]

Me again:

How can I make a contour plot, hold it and the do a 'o' line plot?

The following doesn't work. All I tried returned crap.

octave:60> close
octave:61> contour(z',10,y,x);
octave:62> hold on
octave:63> plot(pval(:,1),pval(:,2),'bo;;');
warning: can't make 2D parametric plot -- setting noparametric...
octave:64> Notice: cannot contour non grid data!
