setCurrentViewport different result on Run and ApplyChanges

[zimare]

Thanks for amazing library.

I try to draw a ComboLineColumnChartData chart as below :

 private void setValShowProperandChart() {
        ColumnChartData columns = generateColumnData();
        LineChartData lines = generateLineData();
        data = new ComboLineColumnChartData(columns, lines);

        calculateAverages();
        periodchart.setComboLineColumnChartData(data);
        periodchart.setOnValueTouchListener(new ValueTouchListener());
        periodchart.setZoomEnabled(false);
        periodchart.setZoomType(ZoomType.HORIZONTAL);
        periodchart.setViewportCalculationEnabled(false);

        Axis axisX = new Axis();
        Axis axisY = new Axis().setHasLines(true);
        axisX.setName("Cycle");
        axisY.setName("Length");
        data.setAxisXBottom(axisX);
        data.setAxisYLeft(axisY);

        Viewport v = new Viewport(periodchart.getMaximumViewport());

        v.left = (float) -0.5;
        v.right = mmmax;
        v.top = v.top + 4;
        periodchart.setMaximumViewport(v);

        v.bottom = 0;
        v.top = v.top + 4;
        v.right = 5;
        periodchart.setCurrentViewport(v);


    }


    private LineChartData generateLineData() {
        ArrayList<Integer> periodData = dbMain.getListForChartPeriod();
        List<Line> lines = new ArrayList<Line>();

        List<PointValue> values = new ArrayList<PointValue>();

        if (periodData.size() < 2) {
            if (tv_warn1 != null) tv_warn1.setVisibility(View.VISIBLE);
        } else {
            for (int j = 0; j < periodData.size(); ++j) {
                values.add(new PointValue(j, periodData.get(j)));
            }

            Line line = new Line(values);
            line.setColor(getActivity().getResources().getColor(R.color.colorAccent));
            line.setCubic(false);
            lines.add(line);
            line.setHasLabelsOnlyForSelected(true);
        }
        LineChartData lineChartData = new LineChartData(lines);

        return lineChartData;
    }


  private ColumnChartData generateColumnData() {
        ArrayList<Integer> listForChartCycles = dbMain.getListForChartCycles();
        int numColumns = listForChartCycles.size();
        List<Column> columns = new ArrayList<Column>();
        if (numColumns < 2) {
            if (tv_warn1 != null) tv_warn1.setVisibility(View.VISIBLE);
        } else {
            if (tv_warn1 != null) tv_warn1.setVisibility(View.GONE);
            List<SubcolumnValue> values;
            for (int i = 0; i < numColumns; ++i) {
                values = new ArrayList<>();
                values.add(new SubcolumnValue(listForChartCycles.get(i), getResources().getColor(R.color.gray400)));
                columns.add(new Column(values).setHasLabels(true));
            }
        }
        ColumnChartData columnChartData = new ColumnChartData(columns);
        return columnChartData;
    }

when i Run(shift+f10) it on emulator everything is missed up(green rectangles):

Then i run it using Apply changes a Restart Activity (Ctrl+f10) ,the chart is perfectly work:

Where is my wrong?
