'MarkerEdgeColor' for Graph/Digraph Nodes

Hello,

I am trying to find a way to apply borders to nodes in a graph to make them look more professional (I have already changed thier color). The 'MarkerEdgeColor' property used for normal plots does not seem to be applicable. Thank you in advance.

I was able to locate the apparent representation of the markers and change some of their properties, but none of my changes to the colour information had any effect .

Yes, changing the color and shape of the nodes is simple enough but I can not find a way to outline the nodes for exmple adding a black border around a shape to make it more defined? Do you have any suggestions?

I see that there is a NodeCData property, so possibly you could just fill in a blob. But I do not see any obvious alpha information for that. And I don't know that the label will be drawn on top or if it would cover the label .

Yes, MATLAB's graph and digraph plots only have one NodeColor property which applies to both the marker's FaceColor and EdgeColor.

The easiest might be to turn off the markers of the GraphPlot object completely and add a scatter plot in which you would be able to set these properties directly for each node. The x- and y- data for the markers on the scatter plot could be taken from the XData and YData properties of the GraphPlot object that's returned from the plot function on a graph.
