Hi,
In my software the user can zoom-in the graph. At a point I need to reset the zoom and the graph need to turn to its first state. Can I do this without removing the chart and then re-drawing???

It is not possible to control this programmatically if you are using a DataZoomTool.

Else you can use the Zoom property on the chart to change the how the whole chart zooms.

e.g.:

private void button1_Click( object sender, EventArgs e )
{
Chart chart = chartControl1.Charts[ 0 ];
chart.View.Zoom = 50; //smaller
//chart.View.Zoom = 100;
//chart.View.Zoom = 150; //bigger
chartControl1.Refresh();
}

I know this thread is old, but I'm posting for posterity. In the DataZoomToolUC example, the code for resetting the zoomed position of the axes is the following, for a ChartControl object called m_ChartControl with a Chart in it:

 

Dim chart As Xceed.Chart.Core.Chart = CType(m_ChartControl.Charts(0), Xceed.Chart.Core.Chart)

chart.Axis(StandardAxis.PrimaryX).Ruler.PagingMode = RulerPagingMode.None

chart.Axis(StandardAxis.PrimaryY).Ruler.PagingMode = RulerPagingMode.None

chart.Axis(StandardAxis.Depth).Ruler.PagingMode = RulerPagingMode.None

m_ChartControl.Refresh()
