Scatter with different markers for categories in colorvar

[Norman]

Hi,

I want to do a scatter plot by regions, with a different marker symbol for each category. My code is:

sysuse census,clear
scatter medage pop, msymbol(Oh Dh Th ) colorvar(region) colordiscrete zlabel(, valuelabel) coloruseplegend

However, I cannot get different markers by region. Can anyone provide suggestions? I appreciate it.

Thanks,

Norman M

Graph colors by variable is introduced in from Stata 18. If you use Stata 18 now, I don't find any wrong in your code. However, if your Stata version is lower than 18, Stata don't support that. https://www.stata.com/new-in-stata/g...s-by-variable/

Edit: Sorry for missing the target. You want to have different symbols not colors. As far as I know, Stata don't support different symbols if you have only one y-variable in implemental twoway scatter command:

msymbol(symbolstylelist)......The "list" specifiers shown above are available only when multiple y-variables are specified, with one specifier allowed per y-variable; otherwise, the standard specifiers listed in the option should be used.

Nick just provide you a feasible workaround.
