Configures the appearance of all constant lines in the widget.

Object

DevExtreme HTML5 Charts ConstantLines

The commonAxisSettings.constantLineStyle object, which is described here, specifies common settings for all constant lines in the chart. To configure only those constant lines that belong to a particular axis, use the following objects.

To configure individual constant lines, use the following arrays of objects.

Individual settings override axis-specific settings which, in their turn, override common settings.

color

Specifies the color of constant lines.

Type:

String

Default Value: '#000000'

This option supports the following colors:

dashStyle

Specifies the dash style of constant lines.

Type:

String

Default Value: 'solid'
Accepted Values: 'dash' | 'dot' | 'longDash' | 'solid'

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 Control. This enum accepts the following values: Solid, LongDash, Dash, and Dot.

label

Configures constant line labels.

Type:

Object

A constant line label displays the value of a constant line.

DevExtreme HTML5 Charts ConstantLine ConstantLineLabel

The commonAxisSettings.constantLineStyle.label object, which is described here, specifies common settings for all constant line labels in the chart. To configure the labels of those constant lines that belong to a particular axis, use the following objects.

  • argumentAxis.constantLineStyle.label
  • valueAxis.constantLineStyle.label

To configure the labels of individual constant lines use the following objects.

  • argumentAxis.constantLines[].label
  • valueAxis.constantLines[].label

Individual settings override axis-specific settings which, in their turn, override common settings.

paddingLeftRight

Generates a pixel-measured empty space between the left/right side of a constant line and the constant line label.

Type:

Number

Default Value: 10

This option depends on the label.horizontalAlignment in the following way.

  • horizontalAlignment is "left" → padding applies to the left side of a constant line;
  • horizontalAlignment is "right" → padding applies to the right side of a constant line;
  • horizontalAlignment is "center" → padding is calculated automatically.

  • argumentAxis.constantLineStyle.label.horizontalAlignment - aligns constant line labels in the horizontal direction. Applies to the constant lines belonging to the argument axis.
  • valueAxis.constantLineStyle.label.horizontalAlignment - aligns constant line labels in the horizontal direction. Applies to the constant lines belonging to the value axis.

paddingTopBottom

Generates a pixel-measured empty space between the top/bottom side of a constant line and the constant line label.

Type:

Number

Default Value: 10

This option depends on the label.verticalAlignment in the following way.

  • verticalAlignment is "top" → padding applies to the top side of a constant line;
  • verticalAlignment is "bottom" → padding applies to the bottom side of a constant line;
  • verticalAlignment is "center" → padding is calculated automatically.

width

Specifies the width of constant lines in pixels.

Type:

Number

Default Value: 1
