Question

我正在使用MPAndroidChart进行折线图。我有5分。以下是我的代码。

 LineChart lineChart = (LineChart) findViewById(R.id.chart);
    lineChart.setDrawBorders(true);
    lineChart.getDescription().setEnabled(false);
    lineChart.fitScreen();
    lineChart.setPadding(0,0,0,0);
    lineChart.getLegend().setEnabled(false);
    lineChart.setDoubleTapToZoomEnabled(false);

    lineChart.getAxisLeft().setEnabled(false);
    lineChart.getAxisRight().setEnabled(true);
    lineChart.getAxisLeft().setStartAtZero(true);

    lineChart.getAxisRight().setDrawAxisLine(true);
    lineChart.getAxisRight().setDrawLabels(true);
    lineChart.getAxisRight().setDrawGridLines(false);

    lineChart.getXAxis().setEnabled(true);
    lineChart.getXAxis().setPosition(XAxis.XAxisPosition.BOTTOM);

    lineChart.getXAxis().setDrawAxisLine(true);
    lineChart.getXAxis().setDrawGridLines(true);
    lineChart.setScaleMinima(3f, 0f);
    lineChart.setBackgroundColor(Color.TRANSPARENT); //set whatever color you prefer
    lineChart.setDrawGridBackground(false);
    lineChart.setTouchEnabled(true);
    lineChart.setDragEnabled(true);
    lineChart.setScaleEnabled(true);
    lineChart.setPinchZoom(false);
    Legend l = lineChart.getLegend();
    l.setVerticalAlignment(Legend.LegendVerticalAlignment.BOTTOM);
    l.setHorizontalAlignment(Legend.LegendHorizontalAlignment.LEFT);
    l.setOrientation(Legend.LegendOrientation.HORIZONTAL);
    l.setDrawInside(true);
    ArrayList<ILineDataSet> dataSets = new ArrayList<ILineDataSet>();

    ArrayList<Entry> values = new ArrayList<Entry>();
    values.add(new Entry(Float.parseFloat("1"), 5));
    values.add(new Entry(Float.parseFloat("2"), 2));
    values.add(new Entry(Float.parseFloat("3"), 6));
    values.add(new Entry(Float.parseFloat("4"), 8));
    values.add(new Entry(Float.parseFloat("5"), 2));

    LineDataSet d = new LineDataSet(values, "Actual kWh ");
    d.setMode(LineDataSet.Mode.CUBIC_BEZIER);
    d.setLineWidth(2.5f);
    d.setCircleRadius(3f);
    d.setCircleColorHole(Color.BLACK);
    d.setValueTextSize(10f);
    d.setValueTextColor(Color.WHITE);
    dataSets.add(d);
    LineData data = new LineData(dataSets);
    lineChart.setData(data);
    lineChart.invalidate();

我能够完成大部分的自定义工作。我的问题是如何只删除topborder？同样在X轴中我得到的数字是1,1.2,1.3，它继续下去。我希望X轴的值为1,2,3,4,5。我该怎么做？

试试这个

此显示垂直线

LineChart lineChart = (LineChart) findViewById(R.id.chart1);
    lineChart.setDrawBorders(false);
    lineChart.getDescription().setEnabled(false);
    lineChart.fitScreen();
    lineChart.setPadding(0,0,0,0);
    lineChart.getLegend().setEnabled(false);
    lineChart.setDoubleTapToZoomEnabled(false);

    lineChart.getAxisLeft().setEnabled(true);
    lineChart.getAxisRight().setEnabled(true);
    lineChart.getAxisLeft().setStartAtZero(false);

    lineChart.getAxisRight().setDrawAxisLine(false);
    lineChart.getAxisRight().setDrawLabels(true);
    lineChart.getAxisRight().setDrawGridLines(false);

    lineChart.getXAxis().setEnabled(true);
    lineChart.getXAxis().setPosition(XAxis.XAxisPosition.BOTTOM);
    lineChart.getAxisLeft().setDrawGridLines(false);
    lineChart.getAxisRight().setDrawGridLines(false);
    lineChart.getXAxis().setDrawAxisLine(true);
    lineChart.getXAxis().setDrawGridLines(true);
    lineChart.setScaleMinima(3f, 0f);
    lineChart.setBackgroundColor(Color.TRANSPARENT); //set whatever color you prefer
    lineChart.setDrawGridBackground(false);
    lineChart.setTouchEnabled(false);
    lineChart.setDragEnabled(false);
    lineChart.setScaleEnabled(false);
    lineChart.setPinchZoom(false);
    Legend l = lineChart.getLegend();
    l.setVerticalAlignment(Legend.LegendVerticalAlignment.BOTTOM);
    l.setHorizontalAlignment(Legend.LegendHorizontalAlignment.LEFT);
    l.setOrientation(Legend.LegendOrientation.HORIZONTAL);
    l.setDrawInside(true);
    ArrayList<ILineDataSet> dataSets = new ArrayList<ILineDataSet>();

    ArrayList<Entry> values = new ArrayList<Entry>();
    values.add(new Entry(Float.parseFloat("1"), 5));
    values.add(new Entry(Float.parseFloat("2"), 2));
    values.add(new Entry(Float.parseFloat("3"), 6));
    values.add(new Entry(Float.parseFloat("4"), 8));
    values.add(new Entry(Float.parseFloat("5"), 2));

    LineDataSet d = new LineDataSet(values, "Actual kWh ");
    d.setMode(LineDataSet.Mode.CUBIC_BEZIER);
    d.setLineWidth(2.5f);
    d.setCircleRadius(3f);
    d.setCircleColorHole(Color.BLACK);
    d.setValueTextSize(10f);
    d.setValueTextColor(Color.WHITE);
    dataSets.add(d);
    LineData data = new LineData(dataSets);
    lineChart.setData(data);
    lineChart.invalidate();

如果您不需要任何网格线

使用

lineChart.getAxisLeft().setDrawGridLines(false);
        lineChart.getAxisRight().setDrawGridLines(false);
        lineChart.getXAxis().setDrawAxisLine(true);
        lineChart.getXAxis().setDrawGridLines(true);

 LineChart lineChart = (LineChart) findViewById(R.id.chart);
        lineChart.setDrawBorders(false);
        lineChart.getDescription().setEnabled(false);
        lineChart.fitScreen();
        lineChart.setPadding(0, 0, 0, 0);
        lineChart.getLegend().setEnabled(false);
        lineChart.setDoubleTapToZoomEnabled(false);

        lineChart.getAxisLeft().setEnabled(true);
        lineChart.getAxisRight().setEnabled(true);
        lineChart.getAxisLeft().setStartAtZero(false);

        lineChart.getAxisRight().setDrawAxisLine(true);
        lineChart.getAxisRight().setDrawLabels(true);
        lineChart.getAxisRight().setDrawGridLines(false);

        lineChart.getXAxis().setEnabled(true);
        lineChart.getXAxis().setPosition(XAxis.XAxisPosition.BOTTOM);

        XAxis xLabels = lineChart.getXAxis();
        xLabels.setGranularity(1f);

        lineChart.getXAxis().setDrawAxisLine(true);
        lineChart.getXAxis().setDrawGridLines(true);
        lineChart.setScaleMinima(3f, 0f);
        lineChart.setBackgroundColor(Color.TRANSPARENT); //set whatever color you prefer
        lineChart.setDrawGridBackground(false);
        lineChart.setTouchEnabled(false);
        lineChart.setDragEnabled(false);
        lineChart.setScaleEnabled(false);
        lineChart.setPinchZoom(false);
        Legend l = lineChart.getLegend();
        l.setVerticalAlignment(Legend.LegendVerticalAlignment.BOTTOM);
        l.setHorizontalAlignment(Legend.LegendHorizontalAlignment.LEFT);
        l.setOrientation(Legend.LegendOrientation.HORIZONTAL);
        l.setDrawInside(true);
        ArrayList<ILineDataSet> dataSets = new ArrayList<ILineDataSet>();

        ArrayList<Entry> values = new ArrayList<Entry>();
        values.add(new Entry(Float.parseFloat("1"), 5));
        values.add(new Entry(Float.parseFloat("2"), 2));
        values.add(new Entry(Float.parseFloat("3"), 6));
        values.add(new Entry(Float.parseFloat("4"), 8));
        values.add(new Entry(Float.parseFloat("5"), 2));

        LineDataSet d = new LineDataSet(values, "Actual kWh ");
        d.setMode(LineDataSet.Mode.CUBIC_BEZIER);
        d.setLineWidth(2.5f);
        d.setCircleRadius(3f);
        d.setCircleColorHole(Color.BLACK);
        d.setValueTextSize(10f);
        d.setValueTextColor(Color.WHITE);
        dataSets.add(d);
        LineData data = new LineData(dataSets);
        lineChart.setData(data);
        lineChart.invalidate();

<强>更新

 //to hide x-axis line 
 xLabels.setAxisLineColor(Color.TRANSPARENT);

MPAndroidChart线图只删除顶部边框android
