Hello Gnuplot Developers!!

This suggestion for enhancement has been requested before, many times, for example see
Re: [Gnuplot-info] Automatic key positioning to avoid overlap

This is extremely important for software that creates scripts automatically, the key position is typically fixed, unless the software developers take the time to study the plotted data and select the best position for the key.
IMHO, we are relying on GnuPLOT for plotting, therefore it would be FANTASTIC if GnuPLOT would offer the option to look for the best location for the key by identifying the area of the plot that is not used. I am attaching two gnuplot examples that clearly show the usefulness of such a capability.

"set key inauto" or whatever is best for backward compatibility.

Looking forward to having this feature in gnuplot.

Best,
Carl

    Hello Carl,
    would it be possible to place the key always outside the plot?
    In my opinion this is better than a quasi-random position inside the plot.

      That's already possible, and has been for eternities.

      Hello Thomas,
      Placing the key outside is always a possibility, however you know that this
      takes as significant real state, and usually it does not look good,
      otherwise everyone would be using this approach all the time.

      IMHO it should not be hard for GnuPlot to figure out which one of the 8
      typical places produces the minimum overlap, and have that as an option.
      Look at my examples, to me GnuPlot would do a great service to the GnuPlot
      community if it was smart enough to select a position that overlaps the
      least with the plotted data.

      Regards,
