Tutorial Membuat Inputan Presentasi Data COVID-19 menggunakan Grafik Pie Chart

Assalamualaikum temen temen :) ini blog Kedua aku, semoga bermanfaat yaa..

selamat mencobaa, semoga berhasil :)

jangan lupa follow ig aku :: @o_viaa11

Terimakasih :))

Cara Membuat Inputan Presentasi Data COVID-19 menggunakan Grafik Pie Chart dengan aplikasi Netbeans (Pertemuan UTS)

1. Buatlah New Project dengan nama OktaviaPurwanto_171011401204

2. Buat New Package dengan nama OktaviaPurwanto_Pertemuan7_8

3. Buat jframe dengan nama "DataInput" 

4. Import jdk dan jfreechart pada library

5. Desain dalam jframe "DataInput" seperti dibawah ini

6. Klik kanan button "SIMPAN" => event => Action => ActionPerformerd dan Masukan source didalam button "SIMPAN"

int positif_OktaviaPurwanto,pdp_OktaviaPurwanto,odp_OktaviaPurwanto,kematian_OktaviaPurwanto;

        positif_OktaviaPurwanto = Integer.parseInt(input1.getText());

        pdp_OktaviaPurwanto = Integer.parseInt(input2.getText());

        odp_OktaviaPurwanto = Integer.parseInt(input3.getText());

        kematian_OktaviaPurwanto = Integer.parseInt(input4.getText());

        hasil1.setText(""+positif_OktaviaPurwanto+" Orang");

        hasil2.setText(""+pdp_OktaviaPurwanto+" Orang");

        hasil3.setText(""+odp_OktaviaPurwanto+" Orang");

        hasil4.setText(""+kematian_OktaviaPurwanto+" Orang");

}

7. Klik kanan button "GRAFIK" => event => Action => ActionPerformerd dan Masukan source didalam button "GRAFIK"

GrafikPieCharts obj1_OktaviaPurwanto = new GrafikPieCharts();

        obj1_OktaviaPurwanto.setNilai(input1.getText(),input2.getText(),input3.getText(),input4.getText());

        obj1_OktaviaPurwanto.setVisible(true);

        dispose();

    }               

8. Buat Java Class dengan nama "GrafikPieCharts"

9. Masukan Source dalam GrafikPieCharts

    JFreeChart Chart2_OktaviaPurwanto = ChartFactory.createPieChart3D("Perbandingan Data Keselamatan",

            Data2_OktaviaPurwanto, false, false, false);

     Panel_OktaviaPurwanto.add(new ChartPanel(Chart1_OktaviaPurwanto));

     Panel_OktaviaPurwanto.add(new ChartPanel(Chart2_OktaviaPurwanto));

     

     Panel_OktaviaPurwanto.setPreferredSize(new Dimension(800, 600));

     setContentPane(Panel_OktaviaPurwanto);

 }

}

10.  klik Run File dan input nilai dalam kotak Positif, PDP, ODP dan kematian, jika sudah klik => button "SIMPAN" , seperti ini ::

11. Klik Grafik dan hasilnya seperti Ini::
