Custom Axes

The Chart control supports the creation of additional custom axes through the use of the chart's CustomAxes collection. Once a custom axis has been added to the collection, in addition to setting the normal axis properties, you will need to set the following properties:

Parent - The Parent property allows you to choose the primary or secondary axis on which your custom axis resides.
PlacementLength - The PlacementLength property allows you to set the length of the custom axis in proportion to the Min and Max property values you have already set for the parent axis.
PlacementLocation - The PlacementLocation property allows you to set the starting location value for the custom axis to appear in relation to the parent axis.

The following code sample demonstrates creating a custom axis, adding it to the Axes collection for the ChartArea, and setting its properties.

' Visual Basic 
' create the custom axis and add it to the ChartArea's Axes collection
Dim customAxisY As New DataDynamics.ActiveReports.Chart.CustomAxis
Me.ChartControl1.ChartAreas(0).Axes.Add(customAxisY)

' set the basic axis properties for customAxisY
customAxisY.LabelFont = New DataDynamics.ActiveReports.Chart.FontInfo(Color.Red, New Font _
	("Arial", 7.0!))
customAxisY.LabelsGap = 1
customAxisY.LabelsVisible = True
customAxisY.Line = New DataDynamics.ActiveReports.Chart.Graphics.Line(Color.Red)
customAxisY.MajorTick = New DataDynamics.ActiveReports.Chart.Tick(New DataDynamics _
	.ActiveReports.Chart.Graphics.Line(Color.Red, 1), New DataDynamics.ActiveReports.Chart _
	.Graphics.Line(Color.Red, 1), 1, 2.0F, True)
customAxisY.MajorTick.GridLine = New DataDynamics.ActiveReports.Chart.Graphics.Line(Color _
	.Red, 1, LineStyle.Solid)
customAxisY.MajorTick.Visible = True
customAxisY.Max = 5
customAxisY.MaxDerived = False
customAxisY.Min = 0
customAxisY.Visible = True

' set the special custom axis properties
customAxisY.Parent = ((CType(Me.ChartControl1.ChartAreas(0).Axes("AxisY"), DataDynamics _
	.ActiveReports.Chart.Axis)))
customAxisY.PlacementLength = 20
customAxisY.PlacementLocation = 30

// C#
// create the custom axis and add it to the ChartArea's Axes collection
DataDynamics.ActiveReports.Chart.CustomAxis customAxisY = new DataDynamics.ActiveReports
	.Chart.CustomAxis();
this.ChartControl1.ChartAreas[0].Axes.Add(customAxisY);

// set the basic axis properties for customAxisY
customAxisY.LabelFont = new DataDynamics.ActiveReports.Chart.FontInfo(Color.Red, new Font
	("Arial", 7F, FontStyle.Regular, GraphicsUnit.Point, ((System.Byte)(0))));
customAxisY.LabelsGap = 1;
customAxisY.LabelsVisible = true;
customAxisY.Line = new DataDynamics.ActiveReports.Chart.Graphics.Line(Color.Red);
customAxisY.MajorTick = new DataDynamics.ActiveReports.Chart.Tick(new DataDynamics
	.ActiveReports.Chart.Graphics.Line(Color.Red, 1), new DataDynamics.ActiveReports.Chart
	.Graphics.Line(Color.Red, 1), 1, 2F, true);
customAxisY.MajorTick.GridLine = new DataDynamics.ActiveReports.Chart.Graphics.Line(Color
	.Red, 1, LineStyle.Solid);
customAxisY.MajorTick.Visible = true;
customAxisY.Max = 5;
customAxisY.MaxDerived = false;
customAxisY.Min = 0;
customAxisY.Visible = true;

// set the special custom axis properties
customAxisY.Parent = (DataDynamics.ActiveReports.Chart.Axis)this.ChartControl1.ChartAreas[0]
	.Axes["AxisY"];
customAxisY.PlacementLength = 20;
customAxisY.PlacementLocation = 30;
