problem drawing a line in the chart

[telbentel]

Hello,

I'm developing a new indicator and for drawing this indicator I have to override the plot method. My indicator Has to draw a line between two bars, the beginning and the end of the zone where this indicator is calculated.

For drawing this line I have to get the coords of this two bars. For doing this I start looking all bars from ChartControl.FirstBarPainted on until I find my two bars and I calculate the offset from this first painted bar to my two bars and after that I calc the coords this way:

initial x = bounds.x + (offset to beginning bar * (ChartControl.BarWidth+ChartControl.BarSpace))

final x = bounds.x + (offset to final bar * (ChartControl.BarWidth+ChartControl.BarSpace))

Bounds is the rectangle object parameter for the plot method and I suppose firstpaintedbar is painted the most possible to the left.

The coords I have for initial x and final x are bigger than bounds.x+bounds.width. How Can I get the width a the bar (distance from beggining of bar to beginning of next bar) and the starting point where bars are plotted?

Thanks in advance

is the chartcontrol class a class developed by ninja or is a generic class of c#?

if it is a ninjatrader class, is there any documentation about this class?

[NinjaTrader_RyanM1]

ChartControl is part of NinjaTrader. Unfortunately it is not documented or supported. I would search our forums to see how other members have used it.

I already solve this problem, I used ChartControl.GetXByBarIdx() to get the right coord.

Just for anyone with the same problem
