Gap in added text to graph

[Mau Aburto]

Hi!

I'm trying to annotate a histogram with the mean and sd. Here's a toy example:

sysuse auto, clear
summarize mpg
local mean: di %9.2fc r(mean)
local sd: di %9.2fc r(sd)
hist mpg, text(.08 30 "{&mu}:`mean', {&sigma}:`sd'")

However, in the graph, there's a weird gap between mu and `mean', and between sigma and `sd'. Does anyone know how I can get rid of them?

Thanks in advance!

Caused by your display format:

di %9.2fc r(mean)

Try

di %3.2fc r(mean)

in this instance.

A comment of a different kind is that you're using population notation for sample mean and SD.
