add another x-trace to charts

how about a x-trace function that sums/avg’s the pens on the chart? either that or the ability to add a pen on the chart that sums or avgs the current pens on the chart.

+1 for another xtrace plus :

  • same xtrace for subplot :smiley:
  • calculated values : delta, slope, area… :smiley: :smiley:

+1 as well for calculated values. That would solve some issues for me… :thumb_left:
