How to make a graph of mean and standard deviation?

[carlos viviano]

Greetings. How can I make this graph of mean and standard deviation in stata? What would the command look like? Variable is "m2" and group is "town".

Here is an example.

webuse grunfeld,clear
collapse invest (sd) investsd=invest,by(company)
gen y1=invest-investsd
gen y2=invest+investsd
twoway rcap y1 y2 company ||scatter invest company,scheme(538w)

Thank you. A question. No need to install a package in the stata? Your quantitative variable is "invest" and your qualitative variable is "company"?

[Raymond Zhang]

yes，you need not install package. I just give you an example.company is quantity variable, if your group variable is qualitative variable，you can use encode command to make it to be quantity variable and then label the variable by your group variable town.

If you have the mean and sd, if if you can use - serrbar - command for that matter.
