I am using MsChart control for a charting application. In that, i am using MouseMove event to display the x-axis dynamic data on graph. Code snippet is as below -


C#
try { //if(EventChart.ChartAreas[0].AxisX.PixelPositionToValue(e.Location.X) == EventChart.Series[0].ChartArea) if (e.Location.X < 0) cursorX = EventChart.ChartAreas[0].AxisX.PixelPositionToValue(0);
                    cursorX = EventChart.ChartAreas[0].AxisX.PixelPositionToValue(e.Location.X);
            cursorY = EventChart.ChartAreas[0].AxisY.PixelPositionToValue(e.Location.Y);

            tipInfo = "Date: " + DateTime.FromOADate(cursorX);

            DataPoint x = new DataPoint(cursorX, cursorY);
                //for (int i = 0; i < 39; i++)
                //{
                //    //bool status = EventChart.Series[i].Points.Contains(x);
                //    if (EventChart.Series[i].Points[Convert.ToInt16(EventChart.ChartAreas[0].CursorX.Position)].ToString() != null)
                //    {
                //        tipInfo += "\n" + GraphSeries[i];
                //        break;
                //    }
                //}
            tooltip.UseFading = true;
            tooltip.SetToolTip(EventChart, tipInfo);
            tooltip.Show(tipInfo, EventChart);
        }




The problem i am facing is that, the mouse move event is getting called, whenever i get into the area where the data is to be displayed, this code updates the x- axis data only for particular left region of my chart. And it does not update x-axis data at tooltip for rest of part of chart.
