legend label in grmap plot

[Dario Maimone Ansaldo Patti]

Dear All,

I use the following command

grmap msp_res1_yp9500, fcolor(blue blue*0.2 red*0.2 red) clmethod(custom) clb(0 1 2 3 4)

to generate the following plot

I would like to change the legend. Specifically, I would like to have something like this:

More specifically, I would lile also to eliminate the last entry (No data).

I tried to use the following:

grmap msp_res1_yp9500, fcolor(blue blue*0.2 red*0.2 red) clmethod(custom) clb(0 1 2 3 4) leglabl(High-High High-low Low-High Low-Low) legend(on)

However, I get an error message saying that laglabl is not allowed. Of course I can modify the entries manually, but since I need to run several plots, it would be useful to be able to do this autonomtically.

Any hint?

FYI, the variable msp_res1_yp9500 takes only four values from 1 to 4 and it is labelled as Low Low; Low High; High Low and High High, respectively. The other entries which correspond to the white color in the map are missing.

I use Stata 17 MP-4.

Thanks in advance,

Dario

The option is -leglabel()- not -leglabl()-.

[Dario Maimone Ansaldo Patti]

Andrew Musau Thanks for spotting the mistake. Indeed I tried using the correct option but nothing changed. Below the graph I generated using leglabel()

As you can see the legend remains unaffected.

[Andrew Musau]

I think you need the -order()- suboption within -legend()-.

legend(order( 1 "High-High" 2 "High-low" 3 "Low-High" 4 "Low-Low"))

[Dario Maimone Ansaldo Patti]

Andrew Musau thanks it worked. I am still in doubt about how to cancel the last entry (no data) but it is still fine what I got thanks to your suggestion

[Andrew Musau]

I think #4 excludes that, the following includes it:

legend(order( 1 "High-High" 2 "High-low" 3 "Low-High" 4 "Low-Low" 5 "No data"))

[Dario Maimone Ansaldo Patti]

Andrew Musau yes you are right. The problem is that if i do not write 5 "No data" for whatsoever reason the colors are mixed up. I would like a specific color for each entry. If I do not include 5 "No data" for instance what is red in the previous map comes out as red*0.2

[Andrew Musau]

I would need to see a reproducible example. Omitting a key in the legend should not affect anything.

[Dario Maimone Ansaldo Patti]

Andrew Musau Solved. You were right: omitting a key in the legend does not modify anything....unless the command is not correctly specified, which was my case. The command I am using now is:

grmap msp_res1_`v', fcolor(blue blue*0.2 red*0.2 red) clmethod(custom) clb(0 1 2 3 4) legend(order( 5 "High-High" 4 "High-low" 3 "Low-High" 2 "Low-Low"))

Thanks for your help.
