극좌표 플롯에서 범례 모양 및 글꼴을 변경할 수 없습니다.

Question

jfreechart 극좌표 플롯을 사용하여 Java에서 하늘 음모를 작성하려고합니다. 모든 것이 잘 작동합니다. 그러나 나는 다양한 시리즈 범례 마커와 크기를 변경할 수 없었습니다.

public class Skyplot { 
     private JFrame plotFrame = null; 

     public static void main (String[] args){ 
      Skyplot sp = new Skyplot(); 
      sp.display();

      plotFrame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); 
      //Display the window.

         double W = plotFrame.getWidth()*0.9; 
         return new Dimension((int)W, (int)H); 
        } 
       }; 
      } 

      private XYDataset getXYDataset() { 
       XYSeriesCollection dataset = new XYSeriesCollection(); 

       XYSeries g01= new XYSeries("G01");

       dataset.addSeries(g01); 

       XYSeries g02= new XYSeries("G02"); 
       series.add(105, 73); 
       dataset.addSeries(g01); 

       XYSeries g03= new XYSeries("G03"); 
       series.add(264, 15); 
       dataset.addSeries(g03); 

       return dataset; 
      } 

     } 

    } 

어떤 생각이 왜 작동하지 않을 : 여기

내 코드에 대한 예입니다? 렌더러에 문제가 있습니까? 도움이 될 것입니다. 고맙습니다.

Answer 1

누락 된 조각이 부모에게 말하는 것 같습니다 AbstractRenderer에서 setShapesVisible().

renderer.setShapesVisible(true); 

나는 모든 모양의 사각형과 전설 더 큰 내부의 텍스트를 만들고 싶어. here을 제안

는 사용자 정의 DrawingSupplier를 사용, 차트 및 범례에 색상과 모양을 조정합니다. 정확한 세부 정보는 사용 사례에 따라 다르지만 기본 접근 방법은 DefaultDrawingSupplier 메서드 getNextPaint() 및 getNextShape()을 재정 의하여 선택한 색과 모양을 반환합니다.

범례 텍스트를 더 크게 만들려면 아래 그림과 같이 차트 LegendTitle을 업데이트하십시오.

LegendTitle title = chart.getLegend(); 
title.setItemFont(new Font(Font.SERIF, Font.BOLD, 24));

Answer 2

나는 위에서 조언을 사용했다. 차트를 만들 수 방법은 이제 다음과 같습니다

private ChartPanel createChartPanel(XYDataset dataset) { 
       // Create chart 
       JFreeChart chart = ChartFactory.createPolarChart("Skyplot", dataset, true, true, false); 

       PolarPlot polPlot = (PolarPlot) chart.getPlot(); 
       polPlot.setRadiusMinorGridlinesVisible(false); 
       polPlot.setBackgroundPaint(Color.WHITE); 
       polPlot.setRadiusGridlinePaint(Color.DARK_GRAY); 
       polPlot.setAngleGridlinePaint(Color.BLACK); 
       polPlot.setDrawingSupplier(new DrawingSupplier() { 
        @Override 
        public Paint getNextFillPaint() { 
         // TODO Auto-generated method stub 
         return null; 
        } 

        @Override 
        public Paint getNextOutlinePaint() { 
         // TODO Auto-generated method stub 
         return null; 
        } 

        @Override 
        public Stroke getNextOutlineStroke() { 
         // TODO Auto-generated method stub 
         return null; 
        } 

        @Override 
        public Paint getNextPaint() { 
         Random rand = new Random(); 
         int r = rand.nextInt(255); 
         int g = rand.nextInt(255); 
         int b = rand.nextInt(255); 

         return new Color(r,g,b); 
        } 

        @Override 
        public Shape getNextShape() { 
         return ShapeUtilities.createDiamond(5f); 
        } 


        @Override 
        public Stroke getNextStroke() { 
         // TODO Auto-generated method stub 
         return null; 
        } 

       }); 

       NumberAxis rangeAxis = (NumberAxis) polPlot.getAxis(); 
       rangeAxis.setTickUnit(new NumberTickUnit(10.0)); 
       rangeAxis.setMinorTickMarksVisible(false); 
       rangeAxis.setRange(0.0, 90.0); 
       rangeAxis.setInverted(true); 

       LegendTitle legend = chart.getLegend(); 
       Font legend_font = new Font("Verdana", Font.BOLD, 18); 
       legend.setItemFont(legend_font); 

       return new ChartPanel(chart){ 
        @Override 
        public Dimension getPreferredSize() { 
         double H = plotFrame.getHeight()*0.9; 
         double W = plotFrame.getWidth()*0.9; 
         return new Dimension((int)W, (int)H); 
        } 
       }; 
      } 

다음과 같이 DrawingSupplier 사용의 결과는 다음과 같습니다 resulting skyplot
