Chart grouping order

I’ve created a bar graph to show my sales by fiscal year, grouped by quarter. Sorting the fiscal years into the correct order is a cinch. However, the order of the quarters isn’t as easy. I’d love for it to display the quarters in order of Q1, Q2, Q3, Q4. Instead, it’s going Q3, Q4, Q1, Q2. I’m guessing that this might perhaps be because Q3 is at the beginning of the calendar year, but who knows.
