Android 条形图的 GraphView 自定义水平标签

Question

我尝试使用 GraphView 在我的应用程序中创建图表

我用下面的代码尝试条形图

@Override
public void initGraph(GraphView graph) {
    // first series is a line
    BarGraphSeries<DataPoint> series = new BarGraphSeries<>(new DataPoint[] {

            new DataPoint(5,5)
    });
    series.setColor(Color.BLUE);
    series.setSpacing(10);
    series.setAnimated(true);
    graph.addSeries(series);

    BarGraphSeries<DataPoint> series1 = new BarGraphSeries<>(new DataPoint[] {
            new DataPoint(2,10)
    });
    series1.setColor(Color.BLACK);
    series1.setSpacing(10);
    series1.setAnimated(true);
    graph.addSeries(series1);


    BarGraphSeries<DataPoint> series2 = new BarGraphSeries<>(new DataPoint[] {
            new DataPoint(3,3)
    });
    series2.setColor(Color.YELLOW);
    series2.setSpacing(10);
    series2.setAnimated(true);
    graph.addSeries(series2);

    BarGraphSeries<DataPoint> series3 = new BarGraphSeries<>(new DataPoint[] {
            new DataPoint(0, 5)
    });
    series3.setColor(Color.RED);
    series3.setSpacing(10);
    series3.setAnimated(true);
    graph.addSeries(series3);

    graph.getViewport().setXAxisBoundsManual(true);
    graph.getViewport().setMinX(0);
    graph.getViewport().setMaxX(5);

    StaticLabelsFormatter staticLabelsFormatter = new StaticLabelsFormatter(graph);
    // legend
    series.setTitle("SQA");
    series2.setTitle("IT");
    series1.setTitle("NOS");
    series3.setTitle("YOUTH");
    graph.getLegendRenderer().setVisible(true);
    graph.getLegendRenderer().setAlign(LegendRenderer.LegendAlign.TOP);
    staticLabelsFormatter.setHorizontalLabels(new String[] {"YOUTH", "NOS", "IT", "SQA"});
    graph.getGridLabelRenderer().setLabelFormatter(staticLabelsFormatter);
}

结果与我预期的不一样，因为只显示 3....1 个标签没有显示。我在这里缺少什么吗？任何答案将不胜感激

Answer 1

条形图系列按 x 值按升序绘制数据点，所以

系列 3(0,5) "YOUTH"
系列 1(2,10) "NOS"
系列 2(3,3) "IT"
系列（5,5），"SQA"

所以标签的顺序应该是 "YOUTH, NOS, IT, SQA" 另外，我不认为水平标签与实际的条形位置相关联，所以我会完全删除底部标签，只留下图例
