设置yAxis的最小值和最大值

Question

我正在使用MPAndroidChart CombinedChart显示折线图和散点图。 除显示区域尝试适应所有散布数据外，此方法工作正常。这样会将y轴减小到最小y值和最大y值之间的范围。

我不希望这种行为，我需要y轴从0开始到最大140。基本上，我正在尝试实现这种显示方式：

这是我正在使用的代码（React Native和react-native-charts-wrapper）。

查看：

<CombinedChart
            data={this.state.data}
            xAxis={this.state.xAxis}
            onSelect={this.handleSelect.bind(this)}
            onChange={event => console.log(event.nativeEvent)}
            drawOrder={["SCATTER", "LINE"]}
            style={styles.container}
          />

状态：

this.state = {
  xAxis: {
    axisMinimum: 0,
    axisMaximum: 120,
    valueFormatter: ["0", "24", "49", "96", "120"],
    granularityEnabled: true,
    granularity: 1
  },
  yAxis: {
    left: {
      axisMinimum: 0,
      axisMaximum: 140
    }
  },


  data: {
    lineData: {
      dataSets: [
        {
          values: [{ x: 0, y: 75 }, { x: 120, y: 75 }],
          label: "Average Heart Rate",

          config: {
            drawValues: false,
            colors: [processColor("green")],
            drawCircles: false,
            lineWidth: 2,
            axisDependency: "RIGHT"
          }
        }
      ]
    },
    scatterData: {
      dataSets: [
        {
          // "HR_vals"
          values: [
