Changing order of the display

[well...@arcsencay.org]

Situation:

I have a chart with the following fields:
- company name
- Year
- Quarter
followed by 10 different reasons why employees would leave (retirement, fired, etc.)

I have it displaying so that it:
- Selects by Year and Quarter
- Displays the data for each reason, grouped by employer name.

I want to change it so that it:
- Selects by Year and Quarter
- Displays the data for each reason grouped by reason

The underlying data is in a MySQL table set up so each employer can add their own information for each quarter. So there is one record for each employer for each quarter.

My attempts so far to adjust the column names, etc., have led to it doing things like adding the quarter number to the chart, etc.

If this is possible, I'd really appreciate information on how to do it.
