[XYVisualization] Color legend bar [message #1420029]

Hello,

I would like to plot a XY graph and use for each point a color depending on a third parameter. The legend of the colors of the points would be displayed on the side of the graph. You can see an example in the picture attached to this post.
Is it possible with the Visualization widgets of Nebula? I looked at the ColorMapRamp already used for IntensityGraph but I cannot find how to use it outside an IntensityGraph.

Regards,
Alain

The Visualization project doesn't provide this feature out of box, but you can extend the current Trace class by overriding the drawPoint() method. I think you can reuse the ColorMapRamp class by creating a new figure that comprises of an XYGraph and a ramp.

Hope it helps,
Xihui

Hello,

I didn't understand the mechanisms of figures and how to create new figures and so on. It's clearer now and I've created a figure with the graph and a custom ColorMapRamp to fit it exactly to our needs.
Thank you for the tip.

Alain
