Class CartesianAxis<T extends org.pepstock.charba.client.configuration.CartesianTick>

java.lang.Object

org.pepstock.charba.client.configuration.Axis

org.pepstock.charba.client.configuration.CartesianAxis<T>

Type Parameters:

T - type of tick to apply to axis

Direct Known Subclasses:

CartesianCategoryAxis, CartesianLinearAxis, CartesianLogarithmicAxis, CartesianTimeAxis

public abstract class CartesianAxis<T extends org.pepstock.charba.client.configuration.CartesianTick>
extends Axis

Axes are an integral part of a chart. They are used to determine how data maps to a pixel value on the chart.
In a cartesian chart, there is 1 or more X axis and 1 or more Y axis to map points onto the 2 dimensional canvas.
These axes are know as 'cartesian axes'.
Axes that follow a cartesian grid are known as 'Cartesian Axes'.
Cartesian axes are used for line, bar, and bubble charts.
Four cartesian axes are included by default.

• linear
• logarithmic
• category
• time

Constructor Summary

Constructors

Modifier	Constructor and Description
protected	CartesianAxis(IsChart chart, ScaleId id, AxisType type, AxisKind kind) Builds the object storing the chart instance and cartesian axis type.

Method Summary

Modifier and Type	Method and Description
Bounds	getBounds() Returns the property controls the scale boundary strategy (bypassed by min/max time options).
IsChart	getChart() Returns the chart instance
protected T	getConfiguration() Returns the configuration element.
Grid	getGrid() Returns the grid element
AxisPosition	getPosition() An axis can either be positioned at the edge of the chart, at the center of the chart area, or dynamically with respect to a data value. To position the axis at the edge of the chart, set the position option to one of: 'top', 'left', 'bottom', 'right'. To position the axis at the center of the chart area, set the position option to 'center'.

abstract T	getTicks() Returns the ticks element
CartesianScaleTitle	getTitle() Returns the scale title element
boolean	isOffset() If true, extra space is added to the both edges and the axis is scaled to fit in the the chart area. This is set to true in the bar chart by default.

void	merge(NativeObjectContainer source, String property) Merge a native object in the this one with a specific property name. This is used by plugins implementation (native java script ones) when they are not using the standard way to add plugin configuration in the options of chart.
void	setBounds(Bounds bounds) Sets the property controls the scale boundary strategy (bypassed by min/max time options).
protected void	setConfiguration(T configuration)
void	setOffset(boolean offset) If true, extra space is added to the both edges and the axis is scaled to fit in the the chart area. This is set to true in the bar chart by default.
void	setPosition(AxisPosition position) An axis can either be positioned at the edge of the chart, at the center of the chart area, or dynamically with respect to a data value. To position the axis at the edge of the chart, set the position option to one of: 'top', 'left', 'bottom', 'right'. To position the axis at the center of the chart area, set the position option to 'center'.
void	setSingleStacked(boolean stacked) Sets if you might want to stack positive and negative values together.
void	setStack(String stack) Sets the stack group. Axes at the same position with same stack are stacked.
