Change format of mlabel in graph twoway connected

[Jacopo Ortis]

Hello everyone,
I have a graph of the following kind:

sysuse auto
collapse (mean) gear_ratio, by(rep78)
graph twoway (connected gear_ratio rep78, mlabel(gear_ratio) mlabposition(12))

However, I haven't been able to find a way to change the format of the labels generated by mlabel(). I'd be glad if someone has figured it out!

For that example I see 2 decimal places, which matches the display format. To get a different number of decimal places, see

help marker label options

for the option mlabformat().

Thank you!
