Report Builder with multiple data series

Question

I am not able to figure out how to create a bar chart using
multiple data series in the Report Builder. I can do it with
explicit CFML coding but not in the Report Builder. I am running MX
version 7 with the current (as of 9/1/07) download of the Report
Builder.
My table contains visit information by site, with standard
demographics on each visit (age, race, gender, etc.) I am trying to
analyze the data by site, for example, race by site.
I am using an SQL statement to sort and group by site &
race. I can get a chart of the number of visits for each site or
the total number of visits by race across all sites. But I can't
get race by site. The SQL statement looks like this:
SELECT race, site, COUNT(*) as counter
FROM visit_info WHERE userid = #session.uid#
GROUP BY site, race ORDER by site, race
Every variation I have tried for showing race by site either
leaves out part of the results or creates a bar chart that has the
race and site categories as separate entities (White, Black,
Chinese, Site1, Site2, Site3, etc). I've also tried creating a
combined variable (site_race) but that doesn't seem to fare any
better.
Any help would be appreciated.

Pop,
Badunit's example is one possible arrangement that you might have described; that is, one column for X values and several columns for Y values. This is the case when you should respond that you are sharing X-values. With all the data in one table, you can select it all at once, so you don't have the problem with dragging additional series into the chart.
The Numbers User Guide PDF's first chapter is the place to start getting your bearings - you will learn how to distinguish Header vs. Body rows and columns. It's worth the effort to take another look at it.
Since you are using a Scatter Chart, it's important not to use a header column for X because X values must be Numeric, as opposed to Text.
