graph-legend order: how to lay 5 legends in first column, while 2 legends in the second column?

[haiyan lin]

Dear all,

I had graphed two categories of y (two y-axes) towards the same x in one graph. The left y-axis has 5 scatter plots, while the right y-axis has 2 scatter plots. I want to separate the legend into two columns, with the first column displaying the left y-axis plots and the second column displaying the right y-axis plots.

I tried to use legend(order (1 2 3 4 5 6 7)...), but it will generate 4 legends in the first column and 3 legends in the second.

Great thanks if you have some suggestions.

Best,
Haiyan

If you are ok with row rather than column orientation of legend you can try the following code at the end of the command you are using.

legend(pos(6) col(5))

set scheme s1mono
gr bar, over(catvar) asyvars leg(order(1 6 2 7 3 8 4 9 5) col(2)) saving(gr1, replace)
*OR EVEN
gr bar, over(catvar) asyvars leg(order(1 8 2 9 3 6 4 7 5) col(2) holes(2 4)) saving(gr2, replace)
gr combine gr1.gph gr2.gph

The examples are aimed at the question, which is as it should be, but I wouldn't use a legend at all in these cases!

Great thanks to @ Andrew Musau ! That's exactly what I want. So happy to get advice here.

Also, many thanks to @ Tarun Choudhary and @ Nick Cox for your kind reply. In my case, legends are needed cause different sources of data are used, which should be declared clearly.
