Determines how to set each data class' color if no individual color is set. The default value, tween
, computes intermediate colors between minColor
and maxColor
. The other possible value, category
, pulls colors from the global or chart specific colors array.
An array of data classes or ranges for the choropleth map. If none given, the color axis is scalar and values are distributed as a gradient between the minimum and maximum colors.
Whether to force the axis to end on a tick. Use this option with the maxPadding option to control the axis end.
Event handlers for the axis.
Color of the grid lines extending from the axis across the gradient.
The dash or dot style of the grid lines. For possible values, see this demonstration.
The width of the grid lines extending from the axis across the gradient of a scalar color axis.
An id for the axis. This can be used after render time to get a pointer to the axis object through chart.get()
.
The axis labels show the number for each tick.. For more live examples on label options, see xAxis.labels in the Highcharts API.
The color of the line marking the axis itself.
The width of the line marking the axis itself.
The triangular marker on a scalar color axis that points to the value of the hovered area. To disable the marker, set marker: null
.
The maximum value of the axis in terms of map point values. If null
, the max value is automatically calculated. If the endOnTick
option is true, the max value might be rounded up.
The color to represent the maximum of the color axis. Unless dataClasses or stops are set, the gradient ends at this value.. . If dataClasses are set, the color is based on minColor and maxColor unless a color is set for each data class, or the dataClassColor is set.
Padding of the max value relative to the length of the axis. A padding of 0.05 will make a 100px axis 5px longer.
The minimum value of the axis in terms of map point values. If null
, the min value is automatically calculated. If the startOnTick
option is true, the min value might be rounded down.
The color to represent the minimum of the color axis. Unless dataClasses or stops are set, the gradient starts at this value.. . If dataClasses are set, the color is based on minColor and maxColor unless a color is set for each data class, or the dataClassColor is set.
Padding of the min value relative to the length of the axis. A padding of 0.05 will make a 100px axis 5px longer.
Color of the minor, secondary grid lines.
The dash or dot style of the minor grid lines. For possible values, see this demonstration.
Width of the minor, secondary grid lines.
Color for the minor tick marks.
Tick interval in scale units for the minor ticks. On a linear axis, if "auto"
, . the minor tick interval is calculated as a fifth of the tickInterval. If. null
, minor ticks are not shown..
On logarithmic axes, the unit is the power of the value. For example, setting. the minorTickInterval to 1 puts one tick on each of 0.1, 1, 10, 100 etc. Setting. the minorTickInterval to 0.1 produces 9 ticks between 1 and 10, . 10 and 100 etc. A minorTickInterval of "auto" on a log axis results in a best guess,. attempting to enter approximately 5 minor ticks between each major tick.. .
If user settings dictate minor ticks to become too dense, they don't make sense, and will be ignored to prevent performance problems.
The pixel length of the minor tick marks.
The position of the minor tick marks relative to the axis line. Can be one of inside
and outside
.
The pixel width of the minor tick mark.
Whether to reverse the axis so that the highest number is closest to the origin. Defaults to false
in a horizontal legend and true
in a vertical legend, where the smallest value starts on top.
If labels are enabled, whether to show the first tick label.
If labels are enabled, whether to show the last tick label.
Whether to force the axis to start on a tick. Use this option with the maxPadding
option to control the axis start.
Color stops for the gradient of a scalar color axis. Use this in cases where a linear gradient between a minColor
and maxColor
is not sufficient. The stops is an array of tuples, where the first item is a float between 0 and 1 assigning the relative position in the gradient, and the second item is the color.
Color for the main tick marks.
The interval of the tick marks in axis units. When null
, the tick interval is computed to approximately follow the tickPixelInterval
.
The pixel length of the main tick marks.
If tickInterval is null
this option sets the approximate pixel interval of the tick marks.
The position of the major tick marks relative to the axis line. Can be one of inside
and outside
.
A callback function returning array defining where the ticks are laid out on the axis. This overrides the default behaviour of tickPixelInterval
and tickInterval
.
An array defining where the ticks are laid out on the axis. This overrides the default behaviour of tickPixelInterval
and tickInterval
.
The pixel width of the major tick marks.
