    BarDataSet Bardataset ;
    BarData BARDATA ;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        chart = (BarChart) findViewById(R.id.chart1);

        BARENTRY = new ArrayList<>();

        BarEntryLabels = new ArrayList<String>();

        AddValuesToBARENTRY();

        AddValuesToBarEntryLabels();

        Bardataset = new BarDataSet(BARENTRY, "Projects");

        BARDATA = new BarData(BarEntryLabels, Bardataset);

        Bardataset.setColors(ColorTemplate.COLORFUL_COLORS);

        chart.setData(BARDATA);

        chart.animateY(3000);

    }

    public void AddValuesToBARENTRY(){

        BARENTRY.add(new BarEntry(2f, 0));
        BARENTRY.add(new BarEntry(4f, 1));
        BARENTRY.add(new BarEntry(6f, 2));
        BARENTRY.add(new BarEntry(8f, 3));
        BARENTRY.add(new BarEntry(7f, 4));
        BARENTRY.add(new BarEntry(3f, 5));

    }

    public void AddValuesToBarEntryLabels(){

        BarEntryLabels.add("January");
