With the PlotAreaClip property of the chart you can get the coordinates of the plot area (rectangle defined by the axes) relative to the chart element. Thus you can calculate the distance you have to displace an element in order to be aligned with the axes. I have attached a sample project for demonstration. Note that the PlotAreaClip property is set when the chart is loaded.
I hope this helps. Please, let us know if you have further questions.
