ValueAxisDefinition

A value axis displays a set of values. It may be in either the X or Y axis, depending on how the chart is setup. For example, in a bar chart, the value axis is on the X axis, and the category axis is on the Y axis, but for a column chart it's the other way around. Scatter and bubble charts have a value axis in both X and Y.

Name	Type	Description
crosshair?	boolean | CrosshairOptions	Whether to show a crosshair for this axis. If you supply 'true', defaults will be used. Otherwise you can supply options to customise the crosshair.
font?	FontSpec	Spec for the font to use for all text on the axis. If you provide a title spec for this axis, any font settings in that spec will override these for the title.
gridLineSize?	number	Width of the grid lines. Defaults to 1 pixel.
id?	string	Axis ID.
inverted?	boolean	Whether or not to invert the axis. If true, the axis will run from max to min instead of min to max.
labelFormatter?	(value:number) => string	Optional formatter for all value labels.
labelPrefix?	string	Optional prefix for all value labels. Will be ignored if you provide a labelFormatter.
labelSuffix?	string	Optional suffix for all value labels. Will be ignored if you provide a labelFormatter.
lineSize?	number	The width of the baseline (if visible). Defaults to 2 pixels.
max?	number	Maximum value for the axis. Defaults to not set. If this is set and your dataset has values above this value their visual representation in bar/column charts will be truncated. If you have a chart with multiple value axes and one or more of them declares a max, the largest value for max will be used for all axes.
min?	number	Minimum value for the axis. Defaults to not set. If this is set and your dataset has values below this value their visual representation in bar/column charts will be truncated. If you have a chart with multiple value axes and one or more of them declares a min, the smallest value for min will be used for all axes.
position?	AxisPosition	The position for the axis: for a Y axis, AXIS_POSITION_START means on the left (this is the default for a y axis), and AXIS_POSITION_END means on the right. For an X axis, AXIS_POSITION_START means on the top, and AXIS_POSITION_END means on the bottom (the default for an X axis).
showGrid?	boolean	Whether or not to show grid lines for each value in the scale. Defaults to false.
showLine?	boolean	Whether or not to show a solid line representing the axis' baseline. Defaults to false.
step?	number	Optional fixed step size for the axis scale.
title?	AxisTitleSpec	Title for the axis. Defaults to empty.
