It does give you that possibility, you just need to find the right options. That command consists of two parts separated by -||-. The first part graphs mean against the categorical variable and the second graphs the standard deviation bars against the categorical variable. To find the options possible after the first command type in Stata -help twoway scatter- and to find the options possible after the second command type in Stata -help twoway rcap-. In the example below I give a silly (and extremely ugly) example of how you can change the way your graph looks: *--------------------- begin example ---------------------- sysuse auto, clear egen mean = mean(price) , by(rep78) egen sd = sd(price), by(rep78) gen upper = mean + sd gen lower = mean - sd scatter mean rep78 , /// plots the mean against rep78 msymbol(S) /// change the symbol to a solid square msize(huge) /// make the marker size huge color(purple) /// change the color of the symbol to purple || /// start a new overlay graph rcap upper lower rep78, /// plots the standard deviation against rep78 lpattern(longdash) /// make the line dashed lwidth(thick) /// make the line thick lcolor(pink) // make the the line pink *---------------------- end example ----------------------- (For more on examples I sent to the Statalist see: http://www.maartenbuis.nl/example_faq ) Hope this helps, Maarten -------------------------- Maarten L.
