proper() function for graph title

[paulvonhippel]

I'm generating scatterplots automatically and I want to make sure the titles are properly capitalized. This doesn't work:

webuse auto, clear
foreach x in mpg headroom trunk {
scatter price `x', title(proper("price and `x'"))
}

The word "proper" appears literally in the title. Is there a way that works?

Maybe

title(`=strproper("price and `x'")')

That works -- wow! How did you figure that out? I'm having trouble parsing your syntax.

This is documented tersely under

help macro

The syntax is that expressions generically exp in

`=exp'

are evaluated and their result is used in the command in which they are embedded.

. di "The answer is `=6 * 7'"
The answer is 42

My expression was

6 * 7

which Stata evaluated; its result was what was shown. (In the case of display, there are other ways to do it, a different point.)

I am not sure about it
