[Gretl-users] Bug in Gretl-Gnuplot interaction under Linux

Dear gretl-friends, I think I've found a bug, but I'm not sure, so please can anybody check it? I'm using gretl on Kubuntu (currently 9:10), Gretl version 1.8.1 and 1.8.6, gnuplot 4.2.6-1 and plots are shifted to the right. Using a "time series plot" the points for let's say 1985 are placed as being in 1986, on XY scatterplot everything is shifted again to the right with respect to the values of variable on the X axis. I've found the same thing on gnuplot and gretl in kubuntu repositories, that is for the gretl 1.8.1 version and associated gnuplot version. If this is not a bug and it can be fixed by some command to gnuplot or some change in gretl settings, I will be very grateful for any advice. With best regards, Jaromir Baxa
