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 TextOrientation TextOrientation { get; set; }
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.
public partial class StripLines : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { // Add chart data AddChartData(); // Adds a threshold line using strip lines. AddThresholdStripLine(); } /// <summary> /// Adds a week of data with values between 20 and 35. /// </summary> private void AddChartData() { // Declare new random variable Random rand = new Random(); // Add a week of data for (int i = 0; i < 7; i++) { chart1.Series[0].Points.AddXY(DateTime.Now.AddDays(i), rand.Next(20,35)); } } /// <summary> /// Adds a horizontal threshold strip line at the calculated mean /// value of all data points in the first series of the chart. /// </summary> private void AddThresholdStripLine() { StripLine stripLine3 = new StripLine(); // Set threshold line so that it is only shown once stripLine3.Interval = 0; // Set the threshold line to be drawn at the calculated mean of the first series stripLine3.IntervalOffset = chart1.DataManipulator.Statistics.Mean(chart1.Series[0].Name); stripLine3.BackColor = Color.DarkGreen; stripLine3.StripWidth = 0.25; // Set text properties for the threshold line stripLine3.Text = "Mean"; stripLine3.ForeColor = Color.Black; stripLine3.TextAlignment = StringAlignment.Near; stripLine3.TextLineAlignment = StringAlignment.Near; stripLine3.TextOrientation = TextOrientation.Auto; // Add strip line to the chart chart1.ChartAreas[0].AxisY.StripLines.Add(stripLine3); } }
