calcXPosValue() always returns 0
Posted: Thu Sep 04, 2008 1:58 pm
I am drawing a chart with multiple lines on it, so now I want to add some custom text next to a line. In order to get the correct position of the text, I have tried the following:
Every time, calcXPos returns zero. I have also tried calling it with values 0, 1, and 2 (explicitly).
Also, as you can see I have tried using the chart, the series (it is displaying price chart candles) and my custom lines to get the point coordinates, but all return zero. Yet they are draw beautifully on my chart.
Here is some more complete code:
.. where idx_timeD is an int like 20 or 30.chart.getAxes().getLeft().calcXPosValue(idx_timeD)
candleSeries.calcXPos(idx_timeD)
line.calcXPos(idx_timeD)
Every time, calcXPos returns zero. I have also tried calling it with values 0, 1, and 2 (explicitly).
