DundasWinChart Assembly > Dundas.Charting.WinControl Namespace > ViewEventArgs Class : Axis Property


Gets the Axis object that the view belongs to.
Axis of the event.

Syntax

Visual Basic (Declaration)  
Public ReadOnly Property Axis As Axis
Visual Basic (Usage) Copy Code
Dim instance As ViewEventArgs
Dim value As Axis
 
value = instance.Axis
C#  
public Axis Axis {get;}

Return Value

An object of type Axis that represents the axis that the view belongs to.

Example

In this example we limit the view along the Y axis for a chart area named "Chart Area 1".  We assume that the Y axis values are 1, 2, 3, etc., and the user isn't allowed to view any data that has a Y value that is greater than 15.
C# Copy Code
using Dundas.Charting.WinControl;
...

// Note that events In C# should be added via the Events button In the Properties window, so
//   that the necessary code Is added To InitializeComponent()
Private void chart1_AxisViewChanging(Object sender, Dundas.Charting.WinControl.CursorEventArgs e){

   If(e.ChartArea.Name ==
"Chart Area 1")
   {

       If(e.Axis.Type == AxisName.Y)
       {

           If(e.NewPosition + e.NewSize > 15)}
           e.NewSize = 15 - e.NewPosition;
       }
   }
}
Visual Basic Copy Code
Imports Dundas.Charting.WinControl
...

Private Sub chart1_AxisViewChanging(ByVal sender As Object, _
ByVal e As Dundas.Charting.WinControl.CursorEventArgs) Handles chart1.AxisViewChanging

    If e.ChartArea.Name = "Chart Area 1" Then

        If e.Axis.Type = AxisName.Y Then

            If e.NewPosition + e.NewSize > 15 Then
                e.NewSize = 15 - e.NewPosition
        End If
    End If
End Sub

Remarks

This property is exposed in the AxisViewChanged and AxisViewChanging events of the root Chart object.

Axis can be used to:

  • determine the axis that the view belongs to via the Axis.Type property (i.e. X, X2, Y and Y2).
  • get and set axis properties (e.g. axis line color, etc.).

Requirements

Target Platforms: Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family, Windows Vista, Windows Server 2008 family
