Creating a Point object. Relationship between SlotIndex, BarIndex, and Points

[neoikon]

Hello,

I'm trying to create a "Point" object (which takes X,Y coordinates), but all I have is a SlotIndex and a Price. So I need to convert these into X,Y values.

I can't seem to find an example of this. I'm also unsure the difference between a SlotValue and a BarIndex.

I see there is a "ConvertToHorizontalPixels" for double values, but this requires a "PresentationSource" as input. I'm not sure what that is.

I'm sure it's easy and I'm missing it! Any help is greatly appreciated.

chartControl.GetXByBarIndex(chartControl.BarsArray[0], SlotIndex);

chartScale.GetYByValue(Price);

Point myPoint = new Point(chartControl.GetXByBarIndex(chartControl.BarsArray[0], SlotIndex), chartScale.GetYByValue(Price));
