In cases where many calls to drawLine() or drawRay() have been made on a chart, it can become cumbersome when those lines get accidentally selected while the user tries to interact with other GUI features. Can anyone suggest a way to programmatically draw a line that cannot be selected accidentally in NinjaTrader 7.x? Thank you in advance for your thoughts.

To answer my own post in a very brief way:

1. in NT7, set chart properties > Allow the selection or drag/drop of chart series = false

2. override the "Plot()" method and use "unsupported by NinjaTrader" coding techniques which involve accessing various objects within "ChartControl" and, if I am not mistaken, GDI drawing methods.

Despite the "unsupported by NinjaTrader" status of the required coding methods, there are apparently many examples available to download for educational purposes. Here is one that I found very useful (see David Lean's posts #1,7, and 9 especially) :
