[Gretl-users] gnuplot issue with histogram

Hi gretl-list members, actually this is a gnuplot issue but I thought that somebody may help me with this. I set up a function (see file attached) to plot some barplots but it does not work as it is planned. I have a matrix A = { 1999, 2.2, 3, 2 ; 2000, 2.8, 1.1, 2 ; 2001, 3, 2.2, 2; 2002, 2.2, 3, 2 } for which I want to plot columns 2 to 4 for each year but at the moment only column 2 is plotted. I suspect to the problem being with the following line in the code: printf "plot '-' using 2:xtic(1) ti col, '' u 3 ti col, '' u 4 ti col\n" I tried different ways but for some reason columns 3 and 4 don't appear . Does anybody have an idea what's wrong with the code here? I am using current CVS on windows. Best, Artur
