RE: how-to show a contourplot together with a point grid


Use Show[plot1,plot2] or better use DisplayTogether from the
Graphics`Graphics` standard package.

Do you just want to add a grid of points on top of the contour plot? Then
maybe,

ContourListPlot[data,
Epilog -> {AbsolutePointSize[4],Point/@grid}]

where grid is a flat list of point locations.

Hi guys,
    i have a matix of dimension {m,n} and make a listcontourplot out of
it. and i have another matrix of the same dimension and make a plot by
: Show[Map[Point,grid]].
   i want to overlap these two plots together. And I have tried using
the second one as the Epilog of the first one, but it did not work. any
ideas?
   generally, how can i overlap two plots in one figure?
   thanks for your attentions and reply
