Access the color palette?

[guerda]

I have an attribute defined to auto-color the nodes based on a grouping attribute.
I would like to add a simple legend with colors and the grouping attribute.

In d3.js I did the following thing, but I seem to miss how I can access force-graph's color palette. Is there any way to do this?

var color = d3.scaleOrdinal(d3.schemeCategory10);
for(int i = 0; i < ...) {
   color(i);
}

@guerda the auto-color scale is just a quick convenience method for assigning different colors based on a simple logic. If you need anything more sophisticated than that, it's better you use the more appropriate nodeColor method. In fact, if you're already declaring a color scale externally, like you shown above, all you need to do is assign that color scale to the nodes. Something like:

.nodeColor(color)

With color being the color scale you've defined in your code.

It worked, thank you. That's how I did it now:

.nodeColor(node` => getColorForPhase([node.rdphase]))
