StripLine.TextOrientation Property
.NET Framework (current version)
Gets or sets the text orientation.
Assembly: System.Web.DataVisualization (in System.Web.DataVisualization.dll)
<BindableAttribute(True)> <PersistenceModeAttribute(PersistenceMode.Attribute)> Public Property TextOrientation As TextOrientation
Property Value
Type: System.Web.UI.DataVisualization.Charting.TextOrientationA TextOrientation value that represents the alignment of the text orientation.
When this property is set to a value of Auto, the text is oriented based on the chart type. For all X-Y chart types other than Bar, X-axis strip line text is oriented horizontally from left to right on the bottom of the strip line. For Bar charts, X-axis strip line text is oriented vertically from top to bottom to the right of the strip line.
The following code example demonstrates how to add a threshold line after the chart control has been added to the design surface. The chart uses a non-recurring strip line to show a calculation of the mean of all data points in a series.
