The Color scale is a specific part added to the controls by NI. If they aren't on the control when dropped from the palette, they can't be shown or added. You can graphically combine controls just by layering them. The color scale is also available on the color ramp and on the intensity graph. You could place one of these on the panel and place the slider over, do a bit of coloring transparent, and you are good to go. Unfortunately, I believe that all the color scales that ship are vertical. I'm sure they'd work horizontal, but nobody ever requested their Z scale on the intensity graph show horizontally. So if you can switch to a horizontal scale that allows the combination to work. Another solution is to use a graphic of the color ramp. Using either the color ramp control or intensity graph or another paint package, build the ramp you want to use, copy it to the clipboard or save the image to file, then load and paste either on the panel, or import into the slider in the control editor. This will work fine as long as you don't want to programmatically change the colors or size of the scale. If you do want to change the colors, consider placing the slider over an intensity graph showing the gradient. You set the scale colors or generate a new ramp for the intensity graph, and as far as the user sees, it is a part of the scale. You could also use the picture control for this. Sorry the workarounds are so involved. You might also want to file a formal request for having color scales on sliders, etc. Greg McKaskle
