[120660021]

Thanks to PhilJay for developing the library！！
Hope to get help，
To achieve the following effects

[120660021]

This is what I am currently implementing.Fill color outside the line，There are some problems
The code is as follows：Help

private void initChart() {
lineChart.setDescription("");
lineChart.setNoDataTextDescription(getResources().getString(R.string.data_is_empty));
lineChart.setTouchEnabled(false);
lineChart.setDragDecelerationFrictionCoef(0.9f);

    // enable scaling and dragging
    lineChart.setDragEnabled(false);
    lineChart.setScaleEnabled(false);
    lineChart.setDrawGridBackground(false);
    lineChart.setHighlightPerDragEnabled(false);

    // if disabled, scaling can be done on x- and y-axis separately
    lineChart.setPinchZoom(false);
    lineChart.setBackgroundColor(Color.TRANSPARENT);

    // add data
    setChartData();
    lineChart.animateX(2000);
    Legend l = lineChart.getLegend();
    l.setEnabled(false);

    XAxis xAxis = lineChart.getXAxis();
    xAxis.setTypeface(mTfLight);
    xAxis.setTextSize(8f);
    xAxis.setPosition(XAxis.XAxisPosition.BOTTOM);
    xAxis.setDrawGridLines(false);
    xAxis.setDrawAxisLine(false);
    xAxis.setValueFormatter(new IAxisValueFormatter() {
        @Override
        public String getFormattedValue(float value, AxisBase axis) {
            return String.valueOf((int)value);
        }

        @Override
        public int getDecimalDigits() {
            return 0;
        }
    });


    YAxis leftAxis = lineChart.getAxisLeft();
    leftAxis.setTypeface(mTfLight);
    leftAxis.setTextSize(8f);
    leftAxis.setDrawGridLines(true);
    leftAxis.enableGridDashedLine(25f, 25f, 0f);
    leftAxis.setGridLineWidth(1f);
    leftAxis.setGranularityEnabled(true);
    leftAxis.setDrawAxisLine(false);
    leftAxis.setValueFormatter(new IAxisValueFormatter() {
        @Override
        public String getFormattedValue(float value, AxisBase axis) {
            return "￥" + (int) value;
        }
