CategoryAxisItemComponent

The time-interval steps when baseUnit is set either to "fit" or "auto". The axis will try to divide the active period into the smallest possible units that yield maxDateGroups or less discrete intervals.

The category index or the date (for date category axis) at which the first value axis crosses this axis. The category indices or the date (for date category axis) at which the value axes cross the category axis (when set as an array). To denote the far end of the axis, set an index greater than or equal to the number of categories.

The background color of the axis.

The base time interval for the date axis. The default base unit is automatically determined by the minimum difference between subsequent categories. Setting baseUnit to "fit" sets such a base unit and categoryAxis.baseUnitStep that the total number of categories does not exceed categoryAxis.maxDateGroups.

Series data is aggregated for the specified base unit by using the series.aggregate function.

The step (interval) between the categories in base units. Setting it to "auto" sets the step to such a value that the total number of categories does not exceed categoryAxis.maxDateGroups. The option is ignored if categoryAxis.baseUnit is set to "fit".

The category names. The Chart creates a category for every item of the array.

The color to apply to all axis elements. Accepts a valid CSS color string, including HEX and RGB. Can be overridden by categoryAxis.labels.color and categoryAxis.line.color.

The configuration options of the crosshair. The crosshair is displayed when the categoryAxis.crosshair.visible option is set to true.

If set to true, the Chart positions categories and series points on major ticks. This removes the empty space before and after the series. The default value is false except for "area", "verticalArea", "rangeArea", and "verticalRangeArea". The option is ignored if the series.type option is set to "bar", "column", "boxPlot", "ohlc", "candlestick", or "waterfall".

The configuration of the axis labels.

The configuration of the axis lines. Also affects the major and minor ticks, but not the grid lines.

The configuration of the major grid lines. These are the lines that are an extension of the major ticks through the body of the Chart.

The configuration of the category axis major ticks.

The last date displayed on a date category axis or the index of the last category displayed on a category axis. By default, the max value is the same as the last category. This is often used in combination with the categoryAxis.min and categoryAxis.roundToBaseUnit options to set up a fixed date range.

The maximum number of groups (categories) to display when categoryAxis.baseUnit is set to "fit" or categoryAxis.baseUnitStep is set to "auto".

The maximum number of ticks and labels to display. Applicable for date category axis.

The first date which is displayed on a date category axis or the index of the first category which is displayed on a category axis. By default, the min value is the same as the first category. This is often used in combination with the categoryAxis.max and categoryAxis.roundToBaseUnit options to set up a fixed date range.

The configuration of the minor grid lines. These are the lines that are an extension of the minor ticks through the body of the Chart.

The configuration of the category axis minor ticks.

The unique axis name. Used to associate a series with a category axis, which utilizes the series.categoryAxis option.

The configuration of the category axis notes.

The name of the pane in which the category axis has to be rendered. If not set, the axis will be rendered in the first (default) pane.

The plot bands of the category axis.

The configuration of the date axis date range labels.

If set to true, the category axis direction is reversed. By default, categories are listed from left to right and from bottom to top.

If set to true, the Chart rounds the first and last date to the nearest base unit.

The selected axis range. If set, the axis selection is enabled. The range is index-based, starting from zero. Categories with indexes in the range (select.from, select.to) will be selected. That is, the last category in the range will not be included in the selection. If the categories are dates, the range has to be also specified with date values. Selection is only supported if the axis is horizontal.

The angle (degrees) of the first category on the axis. Angles increase clockwise with zero to the left. Negative values are acceptable.

The title configuration of the category axis. To display the title, set the categoryAxis.title.text option.

The category axis type. The supported values include category for a discrete category axis and date for a specialized axis for displaying chronological data.

If set to true, the Chart displays the category axis. By default, the category axis is visible.

The week start day when the baseUnit is set to "weeks".
