Extracting x- and y-coordinates from binscatter

[Jon Beck]

I was wondering whether there is an immediate way to collapse one's dataset into the x- and y-coordinates of the scatter plot that results when running the community-supplied command -binscatter- by Michael Stepner.

Many thanks.

Provide a reproducible example. You can use one of Stata's datasets to do so.

Thanks, Andrew, for getting back to me so quickly. My choice of dataset (and variables for that matter) might not be ideal in order to illustrate the usefulness of -binscatter- (ssc) but conceptually speaking, when you run

sysuse auto, clear
binscatter price mpg, controls(weight length)

the output is a scatter plot with roughly 15 data-points. My goal would be to extract the coordinates of those resultant data-points, e.g. by collapsing my data set into the corresponding 15 observations on mpg and price.

Thanks. See

binscatter is from SSC.

My reading of the help is that there is an explicit option savedata() to do precisely this. It worked for me:

sysuse auto, clear
binscatter price mpg, controls(weight length) savedata(foo)

[Jon Beck]

Thanks so much to both of you, Nick and Andrew. Works perfectly!

When I tried to call the help documentation for -binscatter- I received the error message: "request ignored because of batch mode". Should have investigated further...
