BarChart

public BarChart()

Builds the object.

BarChart

protected BarChart(Type extendedType)

Builds the chart.
This is must be extended for controller which are based on this type of chart.

extendedType - type of chart

BarChart

protected BarChart(Type extendedType,
                   boolean doNotCreateOptions)

Builds the chart.
This is must be extended for controller which are based on this type of chart.

Parameters:

extendedType - type of chart

doNotCreateOptions - if true, it ignores the creation of the bar options because the extended class will create own options.
