Basic legend

[Alan Jeddi]

Hi All,
I have created several scatterplots and I have tried using the help function to understand how to create a proper legend but I keep getting error messages.

I used this command: graph twoway scatter iopcc_out mcholesterol3_out || lfit iopcc_out mcholesterol3_out0|| lfit iopcc_out mcholesterol3_out1, sort

Which is a scatterplot that shows the DV and the IV, but presented by Sex. The graph looks like this:

I would like to add in y and x axes, and instead of "fitted values" in the legend, I would like it to read "Male" and "Female"

Alan,

There is a legend option that allows you to do what you want.

graph twoway scatter iopcc_out mcholesterol3_out || lfit iopcc_out mcholesterol3_out0|| lfit iopcc_out mcholesterol3_out1, legend(order(2 “Male” 3 “Female”)) sort

Of course, I haven’t tested this because you haven’t provided any data but I think it should work.

Thanks Lance!
I get the message "“Male” not an integer, option order() ignored

I have sex coded as 0/1 (0 = male).

Do you have any advice on what could be changed to make this work?

Alan,

It's impossible to know how to help you when I don't know what you programmed to get that error. I've reproduced the code I suggested with the auto dataset and I don't get any errors. Here's the code...

sysuse auto, clear

tw sc price mpg || lfit price mpg if foreign==0 || lfit price mpg if foreign==1, legend(order(2 "Domestic" 3 "Foreign"))

As others have suggested to you elsewhere, you increase your chance of getting help if you provide a snippet of data. At the very least, you should share the what you typed along with the error you get.
