Thanks for the reply and sample. Unfortunately, this example shows how to control the spacing between "bars" in the same series, but not the spacing between multiple series.
Your sample may allow me to change back to using a single series since you're showing a different color for each bar. In your sample you use a color "Palette" with a value of "Metro"; are there other palettes pre-defined? If so, is there somewhere I can look to see what colors they represent? More importantly though, how can I define a custom palette so that I can control the colors used?
Thanks again.
