public class BarChart<N extends Number>
extends AdvancedChart<N>

Component wrapper for a Bar chart provided by Google Chart API.

The following code shows sample use of this component:

   import echopoint.google.chart.BarChart;
   import echopoint.google.chart.model.ChartData;

     ...
     final ChartData<Integer> data = new ChartData<Integer>();
     final Integer[] array = new Integer[] { 30,60,70,90,95,110 };
     final List<Integer> xdata = Arrays.asList( array );
     final int xmax = 120;

     data.setXdata( xdata );
     data.setXmax( xmax );

     final BarChart<Integer> chart = new BarChart<Integer>();
     chart.setOrientation( BarChart.Orientation.bhg );
     final ArrayList<ChartData<Integer>> collection = new ArrayList<ChartData<Integer>>();
     collection.add( data );
     chart.setData( collection );

Field Detail

PROPERTY_ORIENTATION

public static final String PROPERTY_ORIENTATION

The property that is used to specify the orientation type for the chart. This property may be styled. Note that this property must be set before the chart can be configured.

Constant Field Values

PROPERTY_SIZE

public static final String PROPERTY_SIZE

The property used to configure the special bar chart width and size. This property is best styled.

See Also:

Constant Field Values

PROPERTY_ZERO_LINE

public static final String PROPERTY_ZERO_LINE

The property used to configure the zero line for the chart. Note that the chart API supports achieving the same effect through the use of data scaling. However, EchoPoint does not support this since we use only simple encoding and not text encoding for the data. This property may be styled, however ever it may be easier to use dynamic setting based upon range of data.
