Also added a coloured background for 1 >r > M. "#12s8B$j$N;XDj$H$J$k!# (J $B. However I worry about this note in the Qt documentation: This is relatively easy to do by setting a counter, then do counter = counter + 1 when your condition is satisfied (I've removed the style for compactness): minval = 100; count1 = 0; count2 = 0 plot 'file' using ($3 > minval && $2 == 0 ? Example of use: bind "ctrl-x" "unset output; exit gnuplot" Gnuplot can plot more than one figure in a frame ( like subplot in matlab ) i.e., try: set multiplot; # get into multiplot mode set size 1,0.5; set origin 0.0,0.5; plot sin(x); set origin 0.0,0.0; plot cos(x) unset multiplot # exit multiplot mode In this case any open output files may not be completed cleanly. The standard way is to tell gnuplot what, where and in what size we want to plot, as in set multiplot set size 0.5, 1 set origin 0,0 plot sin(x) set origin 0.5, 0 plot cos(x) unset multiplot The problem here is that when gnuplot determines how big the actual plot is going to be, it counts the borders, axis label, tics and so on in the size. Maybe it would be clearer to say "gnuplot_qt exiting on read failure". For parsing, the seconds (or the timestamp) are treated as floating numbers. 4L>$N;XDj (J . This bug is still present in windows under version 5.0.3 (using wgnuplot.exe). Printing an error message and continuuing is what reasonably should be happening instead of just freezing.
