Can we render link in different colors by its value? #452

Closed monoglo closed 2 months ago

monoglo commented 3 months ago

In fact, at first I just want event triggered link's flow points animation on every link that has 'true' value, to visualize data's flow. But I haven't found that setting parameter.

So I think it's an another good idea that display link color by its value. Simplily, just boolean value, green to true, gray to false. Then we can customize a map of value to color.

OK, I get it, just add below code:

if (link && link.data) {
    this.renderLink(
        ctx,
        start_node_slotpos,
        end_node_slotpos,
        link,
        true,
        true,
        "green",
        start_dir,
        end_dir
    );
    continue;
}
