AddPlot to existing indicator

[Chippy]

Is it possible to manually code an additional plot to an existing indicator? I'm having no luck.

I have a custom indicator. I would like to add an additional plot with it's own values, to the same indicator.

I do not understand how the Values[] are tied to the AddPlot() that I put into the OnStateChange method, state.defaults. I assumed that the compiler would read that AddPlot() and dimension the Values series accordingly, but it doesn't seem so.

I am unable to assign a value to Values[1][0]. I keep getting an error that the value I'm trying to access is "out of range." I have read the Values and AddPlot() instructions but still can't figure this out. Since adding the second plot was an afterthought, I really didn't want to have to go back through the wizard and start over.

Hello Chippy,

Yes, AddPlot() will automatically add a Series<double> to the Values collection. The first plot added is Values[0], the next call to AddPlot() becomes Values[1], etc.

Below is a link to the help guide..

Note, that State.SetDefaults is only called when adding a new instance of a script. Remove and re-add the instance from the chart to re-run the code in this area. (meaning don't just refresh the ninjascript, actually remove the instance and add a new instance)

If Values.Count is 0, this might indicate an error with the AddPlot() call. Do you see errors appearing on the Log tab of the Control Center?

With Values[1], may I confirm that AddPlot() was called at least 2 times without error in the Log?

Thanks Chelsea. I found a work-around, but I was never able to get the multidimensional array syntax to work. I was having trouble with the added plot being based on cumulative data and hadn't instantiated it or initialized it.
