KOMPUTER GARFIK MEMBUAT GRAFIK DENGAN JAVA NETBEAN (PIE CHART)

KOMPUTER GARFIK MEMBUAT GRAFIK DENGAN JAVA NETBEAN (PIE CHART)

1. Buka Aplikasi NetBeansnya ya (disini saya memakai NetBeans versi IDE 8.2).

2. BUAT NEW PROJECT UTS_INGGIL_171011401480

3. LANJUTKAN MEMBUAT PACKAGE INGGIL;

4. MEMBUAT LABEL JUDUL APLIKASI

5. MEMBUAT CLASS JFROM FRAME CLASS INGGIL JFRAME SEPERTI TERKUHAT

DESEBELAH KANAN

6. EDIT LABEL JUDUL APLIKASI PRESENTASI DATA COVID-19 DAERAH JAWA BARAT

7. LANJUTAN DENGAN MEMBUAT DESKTOP PANE, SEBAGAI LOKASI MEMBUAT FORM INPUT

8. MEMBUAT FORM INPUT, JLABEL DAN JTEXFIELD

9. ATUR WARNA TABELNYA 

10. JADILAH TABELNYA SEPERTI DIBAWAH INI

11. IMPORT LIBRARY JFREE CHART NTUK DAPAT MENJALANKAN PIECHART

12. LANJUTAN MEMBUAT CLASS JINTERNAL FRAME UNTUK PIE CHART

13. KONFIGURASI, BUTTON , TERLIHAT PADA GAMBAR DIBAWAH INI

14. KONFIGURASI SIMPAN

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         // TODO add your handling code here: int a,b,c,d; 

String f = "  Orang"; 

a=Integer.parseInt(jTextField1.getText()); b=Integer.parseInt(jTextField2.getText()); c=Integer.parseInt(jTextField3.getText()); d=Integer.parseInt(jTextField4.getText()); jLabel6.setText(""+a+f); jLabel7.setText(""+b+f); jLabel8.setText(""+c+f); jLabel9.setText(""+d+f);

15. KONFIG BUTTON GRAFIK

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {                                         // TODO add your handling code here: 

Inggil_Piechart pc = new  Inggil_Piechart(); jDesktopPane1.add(pc);

//pc.setNilai(jLabel6.getText(),jLabel7.getText(),jLabel8 .getText(),jLabel9.getText()); pc.setVisible(true); 

//dispose();

} 

16. CONFIG GETLABEL GRAFIK

double n1 =0, n2 =0, n3=0, n4=0, n5=0; 

public void setNilai(String nilai1, String nilai2, String nilai3, String nilai4, String nilai5)

      { try 

         { n1 = Double.parseDouble(nilai1); 

          } catch (NumberFormatException ex){} 

try { n2 = 

Double.parseDouble(nilai2); } 

catch (NumberFormatException ex){} 

try { n3 = Double.parseDouble(nilai3); } 

catch (NumberFormatException ex){} 

try { n4 = Double.parseDouble(nilai4); } 

catch (NumberFormatException ex){} 

try { n5 = Double.parseDouble(nilai5); } 

catch (NumberFormatException ex){} 

17. SET GET GRAFIK

public Inggil_Piechart() { initComponents(); JPanel panel = new JPanel(new GridLayout(2, 2)); DefaultPieDataset dataset1 = new DefaultPieDataset(); dataset1.setValue("Positif", 20); dataset1.setValue("PDP", 30); dataset1.setValue("ODP", 50);

DefaultPieDatasetdataset2 = new DefaultPieDataset(); dataset2.setValue("Data Kematian", 5); dataset2.setValue("Data Termasuk Positif", 95);

JFreeChart chart1 = ChartFactory.createPieChart("Data Penduduk yang Terkena 

Covid-19", dataset1, true, true, true); JFreeChart chart2 = 

ChartFactory.createPieChart("Perbandingan Data Keselamatan", dataset2, true, true, true); PiePlot plot2 = (PiePlot) chart2.getPlot(); plot2.setCircular(false);

panel.add(new ChartPanel(chart1)); panel.add(new ChartPanel(chart2)); panel.setPreferredSize(new Dimension(200, 100)); setContentPane(panel);

18. HASIL INPUT

19. TAMPILAN GRAFIK

20. Lalu kita ketikan Source code pada Java Class PieGrafikInput.
