I think I know what's going on. If you give a generic group to AutoColor, it does a "reasonable" (at least it was to me and my colleagues when we designed it!); it colors each individual member of the generic group independently (since a generic group, as Chris has noted, has no assumption that the things are supposed to treated as a single entity). Thus as output you get a group of colormaps. Which isn't acceptable to colorbar, thus you would need to select out the one you wanted if you wanted to show it. Not ideal, but given the assorted junk one can throw together into a generic group, there isn't really an ideal solution.
Your "changegrouptype" causes AutoColor to color the *whole* thing using a single colormap, which as chris noted, might result in a single outlier screwing up the entire coloring map (actually not screwing it up, since it's working exactly as designed, and as is typically desirable). What I would do is use the generic group, and use Select to select out *one* of the colormaps output by AutoColor, and display that. Cycle through the colormaps (using the Sequencer as input to Select for example) to find out which of your many series members is the outlier.

I know the that AutoColor is working because the colored data, when fed into an Image module, looks great. "Error: Colormap must be a single field, not a Group" However, Chris's pre-coffee comments have provided a line of inquiry; when I use ChangeGridType to force the data going into ColorMap to be a series, or multigrid, I get the ColorBar - unfortunately, the coloring of the image changes ! - if I set ChangeGridType to "generic" I get the original picture back,but the ColorBar breaks as before. Would the inlusion of a bounding box in the source data cause this ? othewise, the input data is a Group composed of 100 - 200 fields - thank you, Craig Schwartz [EMAIL PROTECTED]
