Labels

In This Topic

Labels are represented by the NLabel and are used to display text in the control canvas.

Label position

The NLabel derives indirectly from the NDockPanel class meaning that you can position it at an arbitrary position in the control canvas or dock it to the parent panel. The following code creates a new label at the top left corner of the control:

C#	Copy Code
NLabel label = new NLabel(); label.Text = "Hello world"; label.Location = new NPointL(0, 0); label.ContentAlignment = ContentAlignment.BottomRight; label.TextStyle.FontStyle.EmSize = new NLength(22, NGraphicsUnit.Point); chartControl.Panels.Add(label);

Copy Code

NLabel label = new NLabel();

label.Text = "Hello world";
label.Location = new NPointL(0, 0);
label.ContentAlignment = ContentAlignment.BottomRight;
label.TextStyle.FontStyle.EmSize = new NLength(22, NGraphicsUnit.Point);

chartControl.Panels.Add(label);

Visual Basic	Copy Code
Dim label As New NLabel label.Text = "Hello world" label.Location = New NPointL(0, 0) label.ContentAlignment = ContentAlignment.BottomRight label.TextStyle.FontStyle.EmSize = New NLength(22, NGraphicsUnit.Point) chartControl.Panels.Add(label)

Visual Basic

Copy Code

Dim label As New NLabel

label.Text = "Hello world"
label.Location = New NPointL(0, 0)
label.ContentAlignment = ContentAlignment.BottomRight
label.TextStyle.FontStyle.EmSize = New NLength(22, NGraphicsUnit.Point)

chartControl.Panels.Add(label)

Label text

The text displayed by the label is controlled by the Text property of the NLabel object. The NTextStyle object associated to the label allows you to control the text properties like font, color and orientation and can be accessed via the TextStyle property of the label.

Other

All labels have an associated NInteractivityStyle object which allows them to display custom tooltips or react to mouse action the user is performing on them. These features are discussed in detail in the Interactivity book in the User's Guide.
