Modifying graph in ado-file

[Rolf Lund]

Hello statalist.

I've earlier worked with different graph types and I'm still playing around with some of the functions in a few of them and I keep needing something very specific that I don't know how to fix in the radar-ado.

Below I have attached an example of some data and how the radar chart creates the graph. What I want it to do is, instead of drawing a line between the vectors, I need it to just mark the spot on the vector with a dot/mark/something and NOT connect it with lines. It might sound a little useless but it is for something very specific where I really need to do this exact thing. I've looked in the programs ado-file but I am unsure how to identify the places where it defines the lines and even more so; how to change that spot with something different.

One way is to record the changes you want in Graph Editor and then graph play the recording after the initial graph is created.

I think that if you change line 238 from

 local g "`g' (line obsy`n' obsx`n'`xopt')"

to

 local g "`g' (scatter obsy`n' obsx`n'`xopt')"

you will get what you want. You can add mcolor(`lc') so that your "red" color option continues to work :

local g "`g' (scatter obsy`n' obsx`n'`xopt' mcolor(`lc'))"

Remember to

• rename the program at the top of the file: pr myradar
• rename the file itself: myradar.ado
• save the file to your personal ado path: see output from adopath

Carole gives good advice, but the extension should be .ado, not .do.

Thanks, Nick! I fixed it.

Thank you Carole! Just what I wanted - now I know where to look when I need to modify that!
