ChartBars & ChartControl "Primary Series"

[Curerious]

How do you define "Primary Series" in charts? Is that according to the "Data Series" Tab Applied Ranking? Due to the quote from the documentation it seems to be the case:

The ChartBars class provides GUI access related methods and properties to the primary bars series configured on the Chart through the Data Series menu

But Then the following code doesn't always return the same result when I have multiple charts under the "hosting grid of the chart" :

Print(ChartBars.Properties.Instrument)
Print(ChartControl.BarsArray[0].Properties.Instrument)​

Hello Curerious,

The primary series is always the series which you applied the script to. If you have other series loaded in the chart those are not used at all.
