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
- calculated values : delta, slope, area…
+1 as well for calculated values. That would solve some issues for me…
