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.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;
