I want to add an extra tick on X axis to existing values (I don't want to change them). How can I do it, could somebody help me? There is the code: proc sgplot data=pdf2 noautolegend;
title "Posterior Probability Density - Beta Distribution";
series x=x y=y; /*the curve*/
scatter x=x0 y=pdf0; /*the dot*/
vector x=x0 y=pdf0 /xorigin=x0 yorigin=0 noarrowheads datalabel lineattrs=(color=gray); /*the line below the dot*/
band x=x1 lower=0 upper=y1;
xaxis grid label="x";
yaxis grid label="Beta Posterior PDF";
refline 0 / axis=y;
run; and here should be the value x0 = 0.9 (not hardcoded 0.9, x0 can be changed). I use SAS 9.3, I am hope for your help.
