Hi,

Is there anyway to add markers to a contour plot? with a recent Matlab edition (i.e, 2017 and after)? My contour command looks something like that:

[x,y]=meshgrid(1:10,2:100):
% z is a matrix already predefined on the x and y levels
[c,h]=contour(x,y,z,levels)

When I add 'Marker' to the contour command specifications, I get the following error: unrecognized property Marker for class contour

Best,

It is not possible with single call of contour(). You need to hold the axes and then make a seperate call to plot() or scatter(). For example

Z = peaks(100);
x = [20 50 40 90];
y = [45 23 10 78];
contour(Z)
hold on
plot(x, y, '+', 'LineWidth', 2, 'MarkerSize', 10)
