Graph values from 2d table where series switch places

[avensis1]

Hi

I have a problem that I'm not able to overcome. I have the data as shown below (dataset much larger, but follows the logic below).

- Cells A1:C1 are merged, so are D1:F1 and so on
- I want to show a graph with Months on the X-axis, and Market Share on the Y-axis, and then different lines for the different Companies (Comp A through Comp E)

I have tried to pull out the data with INDEX-MATCH to a separate sheet, where Comp A's market shares are shown on one row, and Comp B's market share in next row and so on, but I cannot get it working to find the corresponding month with the merged cells.

Any tips on how to do this?

Thanks!
