Hi Alexander,

You need to modify the panel location - the following code shows how to revert to the location before you started to drag the panel:

   NCartesianChart chart = (NCartesianChart)nChartControl1.Charts[0];
   nChartControl1.Controller.Selection.SelectedObjects.Add(chart);

   NOffsetTool tool = new NOffsetTool();
   tool.BeginDrag += new EventHandler(tool_BeginDrag);
   nChartControl1.Controller.Tools.Add(tool);

....

  Stack<NPointL> m_LocationStack = new Stack<NPointL>();
  void tool_BeginDrag(object sender, EventArgs e)
  {
   m_LocationStack.Push(nChartControl1.Charts[0].Location);
  }
  private void button1_Click(object sender, EventArgs e)
  {
   if (m_LocationStack.Count > 0)
   {
    nChartControl1.Charts[0].Location = m_LocationStack.Pop();
    nChartControl1.Refresh();
   }
  }
