Forcing variable row height on graph combine

[Laurence Jones]

Hi, I am trying to combine 8 graphs into 4 rows and 2 columns in stata and can I specify for the bottom row to be taller?

Code to combine graphs:

gr combine g1.gph g2.gph g3.gph g4.gph g5.gph g6.gph g7.gph g8.gph, col(2) iscale(0.52) xcommon saving("stata output/CS_graphs") ysize(6) commonscheme

Something like rowheight = 0.2, 0.2, 0.2, 0.4
Thanks in advance for any advice!

You can combine combined graphs. "0.2 0.2 0.4" is doable, as the third row is twice row 1 and row2. You need to do the math for "0.2 0.2 0.2 0.4". Roughly, combine 3 graphs getting a ratio of \(\frac{1}{3}, \frac{1}{3}, \frac{1}{3}\). Then using gr combine, place a bottom margin equal to \(\frac{1}{3}\) so that the graph occupies \(\frac{2}{3}\) of the plot region. Then the combination will give you \(\frac{1}{3}, \frac{1}{3}, \frac{1}{3}, \frac{2}{3}\) that corresponds to "0.2 0.2 0.2 0.4". Here is an illustration for "0.2 0.2 0.4".
