Markerfacecolor in Octave not working?

I'm trying to plot a collection of points as well as a geometrical shape, which is working fine. However, i wanted bigger dots for the points. The standard octave dot ('.') canno开发者_如何学运维t be resized, apparently.

I thought of using the circle marker instead, which can be resized, but i can't seem to manage to "fill" them.

My code: plot(A(:,1),A(:,2),"1o","markersize",5,"markerfacecolor","auto",hull(:,1),hull(:,2),"b",roster(:,1),roster(:,2),".0");

Also, is there a way to make the grid points appear without having to either cope with grid lines, or without having to generate a matrix and plot it?

It seems to be a bug with octave plot function that never got fixed.

I had the same issue with Octave MinGW build. Then I switched to Octave on Cygwin build, and all checked by me plotting options were working fine. For using plotting you will also need to install XWin X Server to Cygwin.
