Hi, here's the recipe: - open credscore.gdt - mark "age" as discrete - plot the frequency distribution -> the result are relatively thick bars (in gnuplot "impulses") - then edit something, e.g. the font size - apply: and the bars become very thin, impossible in the GUI to make them thick again (but feasible in the underlying gnuplot code in the session icon view) This is with the dark2 theme. thanks sven
