MPAndroidchart – 烛台图表为空白

正如标题所说,我试图将MPAndroidChart包含在一个项目中,并且不能让蜡烛显示出来.这是我的代码:

    List<CandleEntry> ceList = new ArrayList<>();
    ceList.add(new CandleEntry(0, 4.62f, 2.02f, 2.70f, 4.13f));
    ceList.add(new CandleEntry(1, 5.50f, 2.70f, 3.35f, 4.96f));
    ceList.add(new CandleEntry(2, 5.25f, 3.02f, 3.50f, 4.50f));
    ceList.add(new CandleEntry(3, 6f,    3.25f, 4.40f, 5.0f));
    ceList.add(new CandleEntry(4, 5.57f, 2f,    2.80f, 4.5f));
    CandleDataSet cds = new CandleDataSet(ceList, "Entries");
    cds.setColor(Color.BLUE);
    cds.setValueTextColor(Color.RED);
    CandleData cd = new CandleData(cds);
    candleStickChart.setData(cd);
    candleStickChart.invalidate();

但我明白了:

MPAndroidchart  – 烛台图表为空白

图表Xml

    <com.github.mikephil.charting.charts.CandleStickChart
    android:id="@+id/CandleStickChart"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

带有折线图的相同代码似乎工作正常.
我有什么想法可能做错了吗?
谢谢!

解决方法:

尝试使用以下代码替换您的代码.

List<CandleEntry> ceList = new ArrayList<>();
    ceList.add(new CandleEntry(0, 4.62f, 2.02f, 2.70f, 4.13f));
    ceList.add(new CandleEntry(1, 5.50f, 2.70f, 3.35f, 4.96f));
    ceList.add(new CandleEntry(2, 5.25f, 3.02f, 3.50f, 4.50f));
    ceList.add(new CandleEntry(3, 6f,    3.25f, 4.40f, 5.0f));
    ceList.add(new CandleEntry(4, 5.57f, 2f,    2.80f, 4.5f));


    CandleDataSet cds = new CandleDataSet(ceList, "Entries");
    cds.setColor(Color.rgb(80, 80, 80));
    cds.setShadowColor(Color.DKGRAY);
    cds.setShadowWidth(0.7f);
    cds.setDecreasingColor(Color.RED);
    cds.setDecreasingPaintStyle(Paint.Style.FILL);
    cds.setIncreasingColor(Color.rgb(122, 242, 84));
    cds.setIncreasingPaintStyle(Paint.Style.STROKE);
    cds.setNeutralColor(Color.BLUE);
    cds.setValueTextColor(Color.RED);
    CandleData cd = new CandleData(cds);
    candleStickChart.setData(cd);
    candleStickChart.invalidate();

在此,您必须指定某些属性.
