It looks like it can be done. What data is in what fields in your portal? (one field for ethnicity and one for gender?)
What options did you select for your chart and how did it fail?
(You may need to base the layout on the portal and use a find or go to related records to restrict the records to the same ones that would be shown in your portal.)
Got it to work but is there a way to change the values on the Verticle (Y) axis to show as dollars instead of a general number?
Not as far as I know. You can add text such as "Amounts in dollars" to the chart.
