[System.Web.UI.PersistenceMode(System.Web.UI.PersistenceMode.Attribute)]
public System.Web.UI.DataVisualization.Charting.TextOrientation TextOrientation { get; set; }

BindableAttribute PersistenceModeAttribute

Examples

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.

C#

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);  
        }  
    }  

Remarks

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.
