Description Shinobu Nagai 2015-01-09 01:29:05 EST 
If running DemoProjectWPF, select "Steema.TeeChart.WPF.Styles.LinePoint" from the "Series" combobox, System.ObjectDisposedException occurs. Please let us know the workaround.

The problem is produced in CanvasWPF class, concretely in the Polygon(bool isStroked, params Point[] p) method when is tried to use DrawGeometry. See code below: 
... 
    public void Polygon(bool isStroked, params Point[] p)
    {
      StreamGeometry geom = GetPathGeometry(p, isStroked);

      if (geom != null)
      {
        PushGuidelines(p);
        g.DrawGeometry(Brush.DrawingBrush, Pen.DrawingPen, geom);
        PopGuidelines();
      }
    }
