GetXByBarIndex unexpected behaviour

[bboyle1234]

It seems that the below call will return a negative value for x:

var x = ChartControl.GetXByBarIndex(ChartBars, Bars.Count + 1)

Is this expected behaviour or a bug? I was hoping to get an x-pixel coordinate that is effectively a couple of bars past the last bar of the chart.

Thanks,
Ben

Hello bboyle1234,

Thanks for writing in.

Due to the limited number of staff available because of the President's Day holiday in the United States, I will be reaching back to you on this matter tomorrow.

Thanks in advance for your patience.

Hello bboyle1234,

Thanks for your patience.

GetXByBarIndex() will not be able to predict the location of where a bar would be if it does not exist. You may perform some math to predict this x coordinate. Please consider the following as an example:

int x = ChartControl.GetXByBarIndex(ChartBars, Bars.Count - 1);
x = ChartControl.GetXByBarIndex(ChartBars, Bars.Count) - x;
x = ChartControl.GetXByBarIndex(ChartBars, Bars.Count) + x;

Please let me know if I may be of further assistance.
