Hi Allin, The only graphs working are Normal and t. (they use set xrange, the rest use set trange) There is a problem with the range value (max float?). I edited the trange to a smaller values and the graphs are OK. Can you reproduce this? Thanks, Hélio --- gnuplot: using pngcairo driver range_from_dist: got -4.5:4.5 get_png_bounds_info(): OK range_from_dist: got -4.5:4.5 get_png_bounds_info(): OK range_from_dist: got 0:1.79769e+308 stderr: ' set trange [0:1.79769e+308] ^ "/home/helio/.gretl/gpttmp.AyreOE", line 16: undefined value ' gretl_errmsg: ' set trange [0:1.79769e+308] ^ "/home/helio/.gretl/gpttmp.AyreOE", line 16: undefined value ' Failed command: 'gnuplot "/home/helio/.gretl/gpttmp.AyreOE"' ---
