public class LinePlotter

extends Plotter

The plotter used to draw a line chart. It only accepts DataSeries of type LineDataSerie. Example of Line chart: // data double[] d1={2,1 ,2 ,3 ,4 ,5 ,4 ,3}; double[] dmax1={0.5,0 ,0.2 ,0.1 ,0.5 ,0,1 ,0}; MaxMinDataSerie data1= new MaxMinDataSerie(d1,null); data1.bubbleChart=true; data1.fillBubble=true; data1.drawPoint=true; data1.pointColor=GraphicsProvider.getColor(ChartColor.GREEN); data1.setMaxMinValues(dmax1,null); double[] d2={2,1 ,2 ,3 ,4 ,5 ,4 ,3}; LineDataSerie data2= new LineDataSerie(d2,new LineStyle(0.2f,GraphicsProvider.getColor(ChartColor.WHITE),LineStyle.LINE_DOTS)); data2.valueFont=GraphicsProvider.getFont("Arial",ChartFont.BOLD,10); data2.valueColor=GraphicsProvider.getColor(ChartColor.YELLOW); data2.valueFont=GraphicsProvider.getFont("Arial",ChartFont.BOLD,10); double[] d3={1,2 ,3 ,2 ,3 ,4 ,1 ,2}; double[] dmax3={0,0.2 ,0.2 ,0 ,0.2 ,0,0.3 ,0}; MaxMinDataSerie data3= new MaxMinDataSerie(d3,null); data3.bubbleChart=true; data3.fillBubble=false; data3.drawPoint=true; data3.pointColor=GraphicsProvider.getColor(ChartColor.WHITE); data3.setMaxMinValues(dmax3,null); double[] d4={1,2 ,3 ,2 ,3 ,4 ,1 ,2}; LineDataSerie data4= new LineDataSerie(d4,new LineStyle(0.2f,GraphicsProvider.getColor(ChartColor.WHITE),LineStyle.LINE_DOTS)); data4.valueFont=GraphicsProvider.getFont("Arial",ChartFont.PLAIN,10); data4.valueColor=GraphicsProvider.getColor(ChartColor.YELLOW); data4.valueFont=GraphicsProvider.getFont("Arial",ChartFont.BOLD,10); // create title Title title=new Title("Price"); title.color=GraphicsProvider.getColor(ChartColor.WHITE); // 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=-1; XAxis.ceroAxis=Axis.CEROAXIS_NO; YAxis.ceroAxis=Axis.CEROAXIS_NO; YAxis.scale.min=0; YAxis.scale.max=6; YAxis.DescColor=GraphicsProvider.getColor(ChartColor.WHITE); YAxis.scaleTickInterval=1; XAxis.scaleTickInterval=1; XAxis.bigTickInterval=1; XAxis.DescColor=GraphicsProvider.getColor(ChartColor.WHITE); String[] lbls={"","8 Jan.","9 Jan.","10 Jan.","11 Jan.","12 Jan.","13 Jan.","14 Jan.","15 Jan."}; XAxis.tickLabels=lbls; XAxis.style =new LineStyle(0.2f,GraphicsProvider.getColor(ChartColor.WHITE),LineStyle.LINE_NORMAL); YAxis.style =new LineStyle(0.2f,GraphicsProvider.getColor(ChartColor.WHITE),LineStyle.LINE_NORMAL); HAxisLabel XLabel= new HAxisLabel("Week",GraphicsProvider.getColor(ChartColor.WHITE),GraphicsProvider.getFont("Arial",ChartFont.ITALIC,12)); VAxisLabel YLabel= new VAxisLabel("Value",GraphicsProvider.getColor(ChartColor.WHITE),GraphicsProvider.getFont("Arial",ChartFont.ITALIC,12)); // plotter LinePlotter plot=new LinePlotter(); // create chart Chart chart=new Chart(title,plot,XAxis,YAxis); chart.XLabel=XLabel; chart.YLabel=YLabel; chart.addSerie(data1); chart.addSerie(data2); chart.addSerie(data4); chart.addSerie(data3); chart.back=new FillStyle(GraphicsProvider.getColor(ChartColor.BLACK));
