Question

我正在使用MPAndroidChart绘制包含大约1400条记录的烛台（ohlc）图表。我试图确保每当用户滚动时，Y轴都会自动缩放。这些是我的图表设置：

    chart.setDrawBorders(false)
    chart.setPinchZoom(false)
    chart.axisRight.setDrawAxisLine(false)
    chart.xAxis.setDrawAxisLine(false)
    chart.xAxis.position = XAxis.XAxisPosition.BOTTOM
    chart.xAxis.setDrawGridLines(false)
    chart.axisRight.setDrawGridLines(false)
    chart.axisLeft.isEnabled = false
    chart.legend.isEnabled = false
    chart.isAutoScaleMinMaxEnabled = true
    var candles = it.data!!

    var candleEntries = candles.mapIndexed { i, c -> c.toCandleEntry(i) }
    var dataSet = CandleDataSet(candleEntries, market.id)

    dataSet.setColor(Color.rgb(80, 80, 80));
    dataSet.shadowColorSameAsCandle = true
    dataSet.setShadowWidth(0.8f);
    dataSet.setDecreasingColor(Color.RED);
    dataSet.setDecreasingPaintStyle(Paint.Style.FILL);
    dataSet.setIncreasingColor(Color.GREEN);
    dataSet.setIncreasingPaintStyle(Paint.Style.FILL);
    dataSet.setNeutralColor(Color.LTGRAY);
    dataSet.setDrawValues(false);
    dataSet.axisDependency = chart.axisRight.axisDependency
    dataSet.barSpace = .25f

    chart.data = CandleData(dataSet)

    chart.setVisibleXRangeMaximum(40.toFloat())
    chart.moveViewToX(candleEntries.size - 40f)

问题是，每当用户滚动时，图表就可能在某些y值之间并开始出现毛刺，如下所示：

有人知道为什么会这样吗？
