Type: Object

horizontalAlignment

Aligns constant line labels in the horizontal direction.

Type: String
Default Value: 'right'
Accepted Values: 'right' | 'center' | 'left'

When using a widget as an ASP.NET MVC Control, specify this option using the HorizontalAlignment enum. This enum accepts the following values: Left, Center and Right.

Show Example:
jQuery

In this example, each argument axis constant line label is aligned differently using the horizontalAlignment option.


                                    

                            

                            

                                    

                                        

                                    

                            

                    

                

        

    



        

        

                

                            

position                





            

                
Specifies the position of constant line labels on the chart plot.


            


            

                                            




            

            

            


                

                            

                                Type:     String

                            

    

        
    

                            

                                Default Value: 'inside'
                            

                            

                                Accepted Values: 'inside' | 'outside'
                            

                

            

                
By default, constant line labels are displayed inside the chart plot near the constant lines they belong to. To place the labels outside the chart plot, set the position option to "outside".



When using the widget as an ASP.NET MVC Control, specify this option using the RelativePosition enum. This enum accepts the following values: Inside and Outside.


            


            
    

        
Show Example:

In this example, the "2013" label is placed outside the chart plot using the position option.

                            

                            

                                    

                                        

                                    

                            

                            

                                    

                                        

                                    

                            

                    

                

        

    



        

        

                

                            

text                





            

                
Specifies the text of a constant line label. By default, equals to the value of the constant line.
