public class BarPlotter
Plotter used to draw a bar chart. It only accepts DataSeries of type BarDataSerie. Example of use: // data double[] d1={1,2,3,4,5,4,2}; BarDataSerie data1= new BarDataSerie(d1,new FillStyle(GraphicsProvider.getColor(ChartColor.CYAN))); data1.border=new LineStyle(0.2f,GraphicsProvider.getColor(ChartColor.BLACK),LineStyle.LINE_NORMAL); //data1.borderType=BarDataSerie.BORDER_RAISED; data1.border=new LineStyle(0.2f,GraphicsProvider.getColor(ChartColor.BLACK),LineStyle.LINE_NORMAL); data1.valueFont=GraphicsProvider.getFont("Arial",ChartFont.BOLD,10); double[] d2={-2,3,4,4.2,6.4,4.5,6.1}; BarDataSerie data2= new BarDataSerie(d2,new FillStyle(GraphicsProvider.getColor(ChartColor.GREEN))); data2.valueFont=GraphicsProvider.getFont("Arial",ChartFont.BOLD,10); data2.border=new LineStyle(0.2f,GraphicsProvider.getColor(ChartColor.BLACK),LineStyle.LINE_NORMAL); data2.negativeStyle=new FillStyle(GraphicsProvider.getColor(ChartColor.RED)); Legend l=new Legend(); l.border=new LineStyle(0.2f,GraphicsProvider.getColor(ChartColor.BLACK),LineStyle.LINE_NORMAL); l.addItem("Company A",new FillStyle(GraphicsProvider.getColor(ChartColor.CYAN))); l.addItem("Company B",new FillStyle(GraphicsProvider.getColor(ChartColor.GREEN))); // create title Title title=new Title("Benefits companies A & B"); // create axis Axis XAxis=new Axis(Axis.HORIZONTAL,new Scale()); Axis YAxis=new Axis(Axis.VERTICAL,new Scale()); XAxis.tickAtBase=true; // draw also first tick XAxis.scale.min=-3; XAxis.scale.max=7; YAxis.scale.min=0; YAxis.scale.max=7; YAxis.IntegerScale=true; YAxis.scaleTickInterval=1; XAxis.scaleTickInterval=1; XAxis.gridStyle=new LineStyle(0.2f,GraphicsProvider.getColor(ChartColor.WHITE),LineStyle.LINE_DOTS); YAxis.gridStyle=new LineStyle(0.2f,GraphicsProvider.getColor(ChartColor.WHITE),LineStyle.LINE_DOTS); String[] lbls={"1998","1999","2000","2001","2002","2003","2004","2005"}; YAxis.tickLabels=lbls; HAxisLabel XLabel= new HAxisLabel("million $",GraphicsProvider.getColor(ChartColor.BLACK),GraphicsProvider.getFont("Arial",ChartFont.BOLD,12)); VAxisLabel YLabel= new VAxisLabel("Year",GraphicsProvider.getColor(ChartColor.BLACK),GraphicsProvider.getFont("Arial",ChartFont.BOLD,12)); // plotter BarPlotter plot=new BarPlotter(); plot.verticalBars=false; plot.interBarSpace=0; // create chart Chart chart=new Chart(title,plot,XAxis,YAxis); chart.XLabel=XLabel; chart.YLabel=YLabel; chart.legend=l; chart.addSerie(data2); chart.addSerie(data1); chart.back=new FillStyle(GraphicsProvider.getColor(ChartColor.LIGHTGRAY));
Field Summary | |

boolean |
barAtAxis
first bar at the axis |
double |
barsBase
start bars at this position |
int |
barWidth
Width of the bar. |
boolean |
cumulative
If true the bars will be display on the top of each other to create a stack bar chart. |
boolean |
cumulativeBackwardsCompatible
leave it to the default (false) unless you are upgrading your version of RChart and you want the values not to be automatically acumulated. |
boolean |
eventChart
set it to true if you want to draw event charts. |
int |
interBarSpace
space between two bars (pixels). |
double |
InterGroupSpace
space between two groups of bars (pixels). |
boolean |
summedLabels
if true labels will be the summed values of the bars |
boolean |
