Multiple Attributes/Quantity by Category
I'm having trouble using the multiple attribute / Quantity by Category symbology in ArcMap and ArcScene. I'm trying to symbolize one attribute by size and another attribute by color (e.g. Trees of different sizes according to age (Category), and different colors according to water use (Quantity)). The trouble is that the color ramp I choose doesn't seem to get applied the way I think it should. Things that should be blue turn out reddish. I read somewhere that the vary by color ramp part doesn't change the entire color of the symbol, only the saturation and value (HSV colors). This seems strange that the second attribute wouldn't symbolize independently from the first. Is this the way it works and is there any good work around for it? I will be updating to version 10 in the next couple of weeks so it may be easier than my current version (9.3.1)
Mapping Center Answer:
I have never heard of this method of rendering the color ramp. However, once you symbolize the features, you can change the color of the blue by simply clicking on those features that are not the right color on the Symbology tab (once you open the Layer Properties dialog) and changing those colors.
