I am using the CW3Dgraph control (parametric surface plot) in a LabVIEW program I have written to graph the the strength of an electromagnetic field over a sphere. The plot color map style is set to use the "color spectrum". I would like to add a color bar scale to the graph so the user can determine the approximate field strength by the color of the plot. Is there an example that could help me with this, does anyone know how to add a color bar scale, or is there some other way to indicate to the user the color's level?
