Proc sgplot: cant add standard deviation to median

[ari]

Hi All,

I cant add standard deviation to calculated median values.

WARNING: Limit bars can only be generated with the MEAN statistic. The LIMITS= option will be
ignored.

SAS prints this warning in the log. 

Is there a way to overcome this issue and show SD with Median values?

My code:

proc sgplot data=test;
vline time / response=chg group=dose stat=median limitstat=stddev;
xaxis label= "Time ";
yaxis label="value";
run;

No.

You'd have to create some sort of custom calculation of median + standard deviation in a data step, and then plot that via SGPLOT or other

Standard Deviation is by definition calculated form a mean, not a median. See https://en.wikipedia.org/wiki/Standard_deviation
