Specifies options of the gauge's major ticks.
Major ticks are calculated automatically based on the scale's startValue and endValue property values. They are visible by default. You can set a custom major tick interval or add custom major ticks using the tickInterval and customTickValues properties respectively. To specify the visibility of major ticks, use the visible and showCalculatedTicks properties. You can also specify the length, width and color of the major ticks using corresponding properties.
Specifies the color of the scale's major ticks.
This option supports the following colors.
- Hexadecimal colors
- RGB colors
- RGBA colors (not supported in Internet Explorer 8)
- Predefined/Cross-browser color names
- Predefined SVG colors (not supported in Internet Explorer 8)
Specifies an array of custom major ticks.
If you set the start and end scale values, major ticks will automatically be calculated and displayed. If you need to add intermediate (minor) ticks between the major ticks, set the visible property of the minorTick configuration object to true. If there are no calculated major ticks at particular scale values, you can set them using the customTickValues property. Assign an array of custom major tick values to this property. To show custom major ticks only, set the showCalculatedTicks property to false.
In this example, the scale's major ticks are generated on the base of the Fibonacci sequence. An array with this sequence is assigned to the customTickValues option. In addition, the automatically calculated major ticks are concealed by setting the showCalculatedTicks option to false.
Specifies the length of the scale's major ticks.
Indicates whether automatically calculated major ticks are visible or not.
Set this property to false when you only need custom major ticks to be visible. The ticks that are calculated based on the specified tickInterval or based on a default tick interval will become invisible.
Specifies an interval between major ticks.
Major ticks are the ticks that are accompanied by labels, which display the corresponding scale values. Use this property to divide the scale by major ticks in a specified interval one from another. If this property is not set, major ticks are automatically arranged so that labels do not overlap each other.
NOTE: The specified tick interval can be changed internally if its value leads to labels overlapping. If you need to prohibit automatic tick arrangement in this situation, set the useTicksAutoArrangement property to false.
Specifies whether or not to expand the current major tick interval if labels overlap each other.
If this property is set to true, the major tick interval always changes automatically when labels overlap each other. For instance, when labels are large due to the formatting that is applied, the tick interval will increase. In addition, when you set a custom tick interval that is so small that labels overlap each other, the tick interval will increase. To prohibit the automatic arrangement of major ticks, set the useTicksAutoArrangement property to false.
Indicates whether scale major ticks are visible or not.
When this property is set to false, both the major ticks that are automatically calculated and the major ticks that are specifically set (see customTickValues) become invisible. To hide the automatically calculated minor ticks only, set the showCalculatedTicks property to false.
Specifies the width of the scale's major ticks.
