How To Draw The Bar Graph In Android Programatically?

can any body hep drawing the bar graph in android according to the data on x and y axis

Solution 1:

charts4j Is another good chart API. It uses the Google charts server to generate the charts and returns them to you as an image.

Solution 2:

I think this librairy can help you : achartengine

Solution 3:

I've successfully used AndroidPlot in the past for doing line graphs, but they also support bar graphs. You could give that a shot.

Solution 4:

publicclassBarchartsampleActivityextendsActivity {
    /** Called when the activity is first created. */static XYMultipleSeriesDataset dataset;
    static XYMultipleSeriesRenderer renderer;
    static XYSeriesRenderer rendererSeries;
    static CategorySeries series;
    static GraphicalView mChartView;
    String xvalstring1,xvalstring2,xvalstring3,xvalstring4,xvalstring5;
    int xvalint1,xvalint2,xvalint3,xvalint4,xvalint5;


     publicvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        LinearLayoutlayout= (LinearLayout) findViewById(R.id.linearlayout);
        Intent intent=getIntent();
        xvalstring1=intent.getStringExtra("xvalstring1").toString().trim();
        xvalstring2=intent.getStringExtra("xvalstring2").toString().trim();
        xvalstring3=intent.getStringExtra("xvalstring3").toString().trim();
        xvalstring4=intent.getStringExtra("xvalstring4").toString().trim();
        xvalstring5=intent.getStringExtra("xvalstring5").toString().trim();     
        xvalint1=Integer.parseInt(xvalstring1);
        xvalint2=Integer.parseInt(xvalstring2);
        xvalint3=Integer.parseInt(xvalstring3);
        xvalint4=Integer.parseInt(xvalstring4);
