Dear Stata users,

I like placing the legend inside the plot, so I modify scheme s2color as follows:
Code:
gridringstyle legend_ring     0 // the default is 3, I change the value to 0
The modified scheme performs well, however, it failed when I place the legend outside the plot region by setting ring(1). I want to know if there's another flexible way to change default ring setting. Thank you.
Code:
sysuse auto, clear
twoway line length weight price, sort
twoway line length weight price, sort legend(ring(1)) // the command failed
