Chart Axis

Axes refer to the lines on a chart that help you understand the scales and dimensions of the data being displayed. The horizontal (x-axis) and vertical (y-axis) axes are used to plot data like time, quantities, percentages, and so on. Use the IAxisOption interface to define the appearance and behavior of a axes in a Data Chart.

Axis Properties

The primary configurable properties of axes available in the IAxisOption interface are listed below.

Property	Description	Sample Preview
type	Defines the axis type as either a "Category Axis" or a "Value Axis". Behavior can vary based on chart types and coordinate system (e.g., Cartesian or Polar).
labels	Controls the visibility of axis labels. Default behavior may vary depending on chart types. Explicit settings are required to override defaults.
axisLine	Determines whether the axis line is displayed. Data Chart provides different default values for various chart types. Explicit settings are required to override defaults.
reversed	Reverses the direction of the axis.
title	Specifies the axis title, including units or other descriptions.
max & min	Sets the maximum and minimum values for the axis range.
position	Determines the location of the axis on the Data Chart.
format	Sets the format information of axis, including the data units and format string.
majorUnit & minorUnit	Sets the interval between scale markings. If the current scale is of the "number" type, set the value directly. If the current scale is not of the type "number" or "date", set the value directly, with the counting rule that the spacing between each category value is 1.
labelAngle	Sets the rotation angle of axis labels (range: -90 to 90 degrees). Note that, currently, this property only works on the first element of the array.
labelStyle	Defines the text style of axis labels.
titleStyle	Specifies the style for axis titles.
lineStyle	Configures the axis line appearance.
majorTickSize & minorTickSize	Sets the length of the major and minor tick marks for the current axis. Major and minor tick marks help locate data points on the axis. Major ticks are used to mark key numerical values, typically spaced farther apart, and are designed to highlight critical data points. Minor ticks represent smaller intervals between major ticks, with closer spacing and finer markings, enabling more precise positioning and comparison. Supported values: none, inside, outside, and cross
majorGrid & minorGrid	Sets to enhance data interpretation. They typically depict finer number intervals, allowing users to view data more precisely. Default values may vary depending on the chart types; for example, grid lines are not shown by default in a "pie" chart. Major grid lines align with the major ticks, highlighting the primary structure of the data. Minor grid lines align with the minor ticks, located between the major grid lines. Major grid lines and tick marks are drawn for each major unit. Minor grid lines and tick marks are drawn for each minor unit. By default, each major unit is separated by one minor grid line and a tick mark.
majorGridStyle & minorGridStyle	Configures the style information for major grid lines and minor grid lines.
dateMode	Sets time spans of the axis in Data Charts like scatter and bubble charts.

Using Code

Refer to the following sample code to configure and customize axes on Data Chats.

Note that this sample uses the "salesTable" data mentioned on the Create Data Charts page. Therefore, make sure you have completed the primary steps outlined on that page to set up a data chart. Once done, you can use the following codes to configure the axes. Additionally, you also have the flexibility to customize the data source according to your specific needs.
