Class BarChartRenderer

java.lang.Object
  com.approximatrix.charting.render.AbstractChartRenderer
      com.approximatrix.charting.render.BarChartRenderer

All Implemented Interfaces:

Renderer

public class BarChartRenderer
extends AbstractChartRenderer

This renderer creates a BarChart. This will only work on a ChartDataModel with non-numeric x-axis values, because I couldn't make any sense out of a bar chart with a numeric x-axis like in a line chart.

Constructor Detail

BarChartRenderer

public BarChartRenderer(CoordSystem cs,
                        ChartDataModel model)

Creates new BarChartRenderer

Parameters:

cs - the CoordSystem used to translate into pixel space

model - the DataModel that should be rendered

BarChartRenderer

public BarChartRenderer(CoordSystem cs,
                        ChartDataModel model,
                        java.text.DecimalFormat topFormat,
                        java.awt.Font topFont,
                        float boxWidth)

Creates new BarChartRenderer

Parameters:

cs - the CoordSystem used to translate into pixel space

model - the DataModel that should be rendered

topFormat - if not null, the values that each box represents will be printed at the top of the box.

boxWidth - a value between 0.0 and 1.0 representing how much of the alloted space each box should consume. If 1.0 is passed, then each box will completely fill it's allotted space, alternately I suggest you don't pass 0.0

Method Detail

renderChart
