[Swarm-Support] EZGraph line colours

[Michael Carney]

Hi,

The EZGraph class that I have only seems to include these twelve colors,

"blue", "orange", "yellow", "green",
"red", "purple", "violet", "cyan",
"grey50", "darkgreen", "goldenrod", "seagreen"

How do I extend this. I'm using swarm-2.1.1 and java, maybe a newer version of 
swarm would have more colors, where can I download a new version?

Thanks,

You might try accessing the underlying graph components directly,
instead of going through EZGraph.

Then define something like:
static const char * colors[NUMCOLORS] =
{
  "blue", "orange", "yellow", "green",
  "red", "purple", "violet", "cyan",
  "grey50", "darkgreen", "goldenrod", "seagreen",
  "navy", "turquoise",
  "khaki", "gold", "brown", "salmon",
  "pink", "magenta", "maroon", "thistle"
};

And put as many values as you want in there, as long as they
comply with the colors Tcl/Tk understands.

When you define your graph element (the thing that actually draws
data to the graph), you can set the color directly using:

    [ge setColor: colors[colorNdx % NUMCOLORS]];
