[Octave-bug-tracker] [bug #47765] legend text covers the line and marker.

[Rik]

Follow-up Comment #4, bug #47765 (project octave):

Confirmed.  I agree with Pantxo's analysis as well.

I'm not sure whether the easiest solution would be to prevent a legend axes
object from ever getting selected, or whether we need to disable autoscaling
when the axes object is a legend.

For the second choice, the code is in libgui/graphics/Canvas.cc.


void
Canvas::canvasAutoAxes (const graphics_handle& handle)
{
  gh_manager::auto_lock lock;

  graphics_object go = gh_manager::get_object (handle);

  if (go.valid_object ())
    {
      figure::properties& fp = Utils::properties<figure> (go);

      graphics_handle ah = fp.get_currentaxes ();

      graphics_object ax = gh_manager::get_object (ah);

      if (ax.valid_object ())
        {
          axes::properties& ap = Utils::properties<axes> (ax);

          autoscale_axes (ap);

          redraw (true);
        }
    }
}


After getting the currentaxes into the variable ah, we could check that it
doesn't have the legend property before continuing.
