JavaScript/jQuery PolarChart - argumentAxis.constantLineStyle

Use this object to set the appearance options for the constant lines of both the argument and value axes. For example, you can change the color, dash style and width of the line using corresponding options or define the look of the labels using the label object.

To specify styles for the constant lines of the argument and value axis separately, use the constantLineStyle object within the argumentAxis or valueAxis configuration object correspondingly. Note that the options that are set within these objects override the corresponding options that are set within the commonAxisSettings.constantLineStyle object.

In addition, you can define the appearance of each constant line individually. For more information, refer to the argumentAxis.constantLines or valueAxis.constantLines object description.

This option supports the following colors:

• Hexadecimal colors
• RGB colors
• RGBA colors
• Predefined/cross-browser color names
• Predefined SVG colors

The following dash styles are available:

• solid
  The border is a solid, continuous line.

• longDash
  The border is displayed using long dashes.

• dash
  The border is displayed using dashes.

• dot
  The border is displayed using dots.

• Any combination of 'longDash', 'dash' and 'dot'
  The border is displayed by repeating the specified combination. For instance, 'dashdotdash'.

Use the DashStyle enum to specify this option when the widget is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values: Solid, LongDash, Dash, and Dot.

A constant line label shows information on the constant line. Use the label object to configure all the constant line labels simultaneously. Within this object you can set font options, a position and text using corresponding fields.

To specify styles for the constant line labels of the argument and value axis separately, use the argumentAxis.constantLineStyle.label or valueAxis.constantLineStyle.label configuration object correspondingly. Note that the options that are set within these objects override the corresponding options that are set within the commonAxisSettings.constantLineStyle.label object.

In addition, you can define the appearance of each constant line label individually. For more information, refer to the argumentAxis.constantLines.label or valueAxis.constantLines.label object description.
