Include slope value in graph

[Mari Meir]

Dear members,

I have a question, but I am also open for suggestions.

I am preparing for a presentation to individuals that have very basic skills in econometrics (if so...), so I am thinking about relying much more in graphics.

The attached graphic relates to campaigns of fundraising to public goods.

I would like to explain very briefly the slope of each line, and I was wondering whether I can include the value of the slope used by Stata to calculate lfit.

(PS. Again, any suggestion would be welcome).
(PS2. I used the scatterplot and lfit for brevity and more clarity, given the audience - reason why I did not use marginsplot, but feel free to tell me if you think it is completely nonsense.)

Best,

Mari

there was no attachment (please see the FAQ on how to show graphs); the user-written command aaplot does what I think you want; use search to find it and download it

Oh, sorry, thank you for the heads up, Rich Goldstein, I had just forgotten.

Here it is.

I'll look for the user-written command you mentionned. If you have any other hint by looking at the graph, I'll be more than happy to hear it.

aaplot (SSC) as kindly recommended by Rich Goldstein should give you coding ideas.

I see two typos in your graph: should be donors, probabilities.

Nick Cox , thank you very much, I will correct it. I have downloaded aaplot, and it did what I wanted (very good, neat program).
