Description yeray alonso 2014-06-30 06:50:19 EDT

At the dodraw funtion in Tee.CursorTool the initial position is initialized as follows:

  this.calcRect();

  if (!old)
    old=new Point(r.x+0.5*r.width, r.y+0.5*r.height);

Since both r and old are local variables, the user can't set them out of the class.

Comment 1 yeray alonso 2014-06-30 06:52:21 EDT

Fix suggestion:

We could add a property to "force" the cursor to be drawn at a given position. Adding this next to the code above at the dodraw funtion in Tee.CursorTool:

  this.calcRect();

  if (!old)
    old=new Point(r.x+0.5*r.width, r.y+0.5*r.height);

  if (this.force)
    old=this.force;

So the customer will be able to do something like this:

  Chart1.draw();
  cursor.start=new Point(Chart1.axes.bottom.calc(1), null);
