Initialize a Series of Lists
Hello, just curious if there is an example of initializing a series of lists. I'd like to use a series of lists because i do not know how many elements are going to be computed in each bar. I found an example for creating and initializing a list (Initialize List) but for some reason I am unable to get it to work with a series of lists. Any help would be appreciated. Thanks!

the declaration, keep it separate from the initial assignment.
Declare your variable, but do not initialize it (or initialize to null),
Code:private Series<List<double>> MySeries = null;
Code:protected override void OnStateChange() { switch (State) { case State.SetDefaults: MySeries = new Series<List<double>>([COLOR=#e74c3c]this[/COLOR]); break; .... } }

Thank you for your response and your help. I had that earlier too and could get it through compile but then get a " Error on calling 'OnBarUpdate' method on bar 20: Object reference not set to an instance of an object. So, i thought it was an initialization issue.
Maybe it is my .Add statement. I'll get a print before the assignment but not after.
For testing purposes, i have the following:
Code:private Series<List<double>> MySeries = null;
Code:else if (State == State.DataLoaded) { MySeries =new Series<List<double>>(this); }
Code:double test_double = 4.3; MySeries[0].Add (test_double); Print(MySeries[0][0]);
