Sean,
I initially thought of this too, but OP did specifically call for a bar
chart. If this is fleixible and column can be used great. If not:
A "bar" chart places labels on y-axis, while a line chart places labels on
x-axis. While it would seem one should be able to place both on the y-axis,
XL won't allow this. It insists on keeping the line and bars on seperate
axes, thus distorting the chart.
While I've been working on possible work arounds, I'm afraid I haven't found
anything yet. =(
BTW, I'm pretty sure my XL only lets me pick "Chart Types" not "Customer
Types" although that would be nice some days...
