[Tex/LaTex] How to mark a node in a graph with a pattern

graphstikz-pgf

I would like to mark my nodes in a graph without using colors because it will be printed in black and white. For example by drawing a vertical line in the first vertex, a horizontal line in the second, two lines in the third,… . Or if there is a better way to do this, I would like to here it.

Thank you for your time.

Best Answer

Instead of patterns, I would recommend that you use a combination of different shadings, and line styles (thin, thick, ultra thick, or even draw=none) to distinguish the nodes. You can also adjust the text color (as suggested by @Jake), and use dotted or dashed lines (a few of which are probably to be avoided):
