[pstricks] \PTick\iA extraction of abscissa and ordinate

[Jacques RUBIN]

Hi!

I used this code below with PSTricks and mulitdo which works fine, but I
would like to extract the abscissa and the ordinate values of the
different points \PTick\iA. What is the command to make this "extraction?"


\def\P{sqrt(9*x)+1}
\pspolylineticks[metricInitValue=1,Os=1,Ds=2,linewidth=1pt,ticksize=-4pt
4pt,linecolor=Green]{P}{ ds }{0}{7}%
\multido{\iA=1+1,\iB=3+2}{6}{ \uput{6pt}[d](PTick\iA){\tiny \iB} }
