JavaScript/jQuery Chart - commonAxisSettings.constantLineStyle

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.

• argumentAxis.constantLineStyle
• valueAxis.constantLineStyle

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

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

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

This option supports the following colors:

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

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 displays the value of a constant line.

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.

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.

See Also

• 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.

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.

See Also

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