Class NumericAxis<M>

java.lang.Object
  com.sencha.gxt.chart.client.chart.axis.Axis<M,V>
      com.sencha.gxt.chart.client.chart.axis.CartesianAxis<M,Number>
          com.sencha.gxt.chart.client.chart.axis.NumericAxis<M>

Type Parameters:

M - the data type that the axis uses

All Implemented Interfaces:

AxisHandler.HasAxisHandlers, AxisItemOutEvent.HasAxisItemOutHandlers, AxisItemOverEvent.HasAxisItemOverHandlers, AxisSelectionEvent.HasAxisSelectionHandlers

public class NumericAxis<M>
extends CartesianAxis<M,Number>

An axis to handle numeric values. This axis is used for quantitative data as opposed to the category axis. You can set minimum and maximum values to the axis so that the values are bound to that. If no values are set, then the scale will auto-adjust to the values.

Nested Class Summary

class

NumericAxis.Step Class that represents a tick mark step in CartesianAxis.

Constructor Summary

NumericAxis()
Creates a numeric axis.

Method Summary

void	addField(ValueProvider<M,? extends Number> field) Adds a ValueProvider to provide data to a field of the axis.
void	calcEnds() Calculate the start, end and step points.
double	getMaximum() Returns the maximum value of the axis.
double	getMinimum() Returns the minimum value of the axis.
boolean	isAdjustMaximumByMajorUnit() Returns true if the axis adjusts the minimum.
boolean	isAdjustMinimumByMajorUnit() Returns true if the axis adjusts the maximum.
void	setAdjustMaximumByMajorUnit(boolean adjustMaximumByMajorUnit) Sets true if the axis adjusts the maximum.
void	setAdjustMinimumByMajorUnit(boolean adjustMinimumByMajorUnit) Sets true if the axis adjusts the minimum.
void	setMaximum(double maximum) Sets the maximum value of the axis.
void	setMinimum(double minimum) Sets the minimum value of the axis.
