Thanks - I just tried this out - but seem to have the same problem. As far as I can make out, the DataDrawingCanvas works in the same way - via the internal chart dimensions as per their axes rather than through pixel co-ordinates within the canvas itself...
So to draw the halfway line in my example, I'd use something like this: canvas.drawRect(Edge.LEFT,Edge.TOP,6,Edge.BOTTOM); Where the '6' is the halfway point on the chart by virtue of being the closest datapoint. I can't see any way of providing a more accurate value here. For example, can I draw ten rectangles on the back of the chart side by side, each of equal width, to take up the full width of the DataDrawingCanvas? I can't figure out how to do this - any clues?
