I have to create a line chart that will include some series and a vertical line whose position can be modified dynamically after the creation of the chart. I'm using the property notes to display the vertical line:
// initial note (vertical line)
The position of the vertical line is updated by external events with the following code:
The problem is that when the notes are modified the notes and the series are redrawn and I would like that only the notes are redrawn.
Is it possible to modify and redraw only the notes of a chart? Is it correct use notes to achieve this functionality?
Thanks in advance.
