java - 如何在android中创建水平滚动分组条形图

Question

我需要创建这种类型的水平滚动分组条形图

下面是我到目前为止尝试过的一些链接

• How to create a BarChart with grouped bars with MPAndroidChart?
• MPAndroid Chart not displaying any labels for xAxis , what is missing?
• Scrollable BarChart with possibility to touch each bar using MpAndroidChart?
• MPAndroidChart BarChart horizontal / vertical
• How can I make my HorizontalBarChart scrollable?

这是我到目前为止尝试过的代码，但我不知道如何创建与上图完全相同的分组条形图并使其水平滚动

class ChartFragment : BaseFragment() {

    var barEntries: ArrayList<BarEntry> = ArrayList()
    var barEntries1: ArrayList<BarEntry> = ArrayList()
    var barEntries2: ArrayList<BarEntry> = ArrayList()
    var barEntries3: ArrayList<BarEntry> = ArrayList()
    var barEntries4: ArrayList<BarEntry> = ArrayList()

    val xAxisLabel: ArrayList<String> = ArrayList()

    lateinit var rootView: View
    override fun onCreateView(
            inflater: LayoutInflater, container: ViewGroup?,
            savedInstanceState: Bundle?
    ): View? {
        rootView = inflater.inflate(R.layout.fragment_insigts, container, false)

        val description = Description()
        description.text = ""
        rootView.barChart.description = description

        getEntries()

        rootView.barChart.axisLeft.setDrawGridLines(false)
        rootView.barChart.xAxis.setDrawGridLines(false)
        rootView.barChart.axisLeft.setDrawAxisLine(false)


        rootView.barChart.axisRight.setDrawGridLines(false)
        rootView.barChart.axisLeft.setDrawGridLines(false)
        rootView.barChart.xAxis.setDrawGridLines(false)


//        rootView.barChart.xAxis.isEnabled = false
        rootView.barChart.axisLeft.isEnabled = false
        rootView.barChart.axisRight.isEnabled = false

        xAxisLabel.add("Mon")
        xAxisLabel.add("Tue")
        xAxisLabel.add("Wed")
        xAxisLabel.add("Thu")
        xAxisLabel.add("Fri")
        xAxisLabel.add("Sat")
        xAxisLabel.add("Sun")

        val xAxis = rootView.barChart.xAxis

        xAxis.valueFormatter = IndexAxisValueFormatter(xAxisLabel)


        rootView.barChart.setVisibleXRangeMaximum(20f)
        rootView.barChart.moveViewToX(10f)

        return rootView
    }



    private fun getEntries() {

        barEntries.add(BarEntry(1f, 70f))
        barEntries.add(BarEntry(2f, 80f))


        barEntries1.add(BarEntry(1f, 50f))
        barEntries1.add(BarEntry(2f, 40f))


        barEntries2.add(BarEntry(1f, 200f))
        barEntries2.add(BarEntry(2f, 30f))


        barEntries3.add(BarEntry(1f, 60f))
        barEntries3.add(BarEntry(2f, 30f))

        barEntries4.add(BarEntry(1f, 70f))
        barEntries4.add(BarEntry(2f, 80f))



        val barDataSet = BarDataSet(barEntries, "1")
        barDataSet.color = Color.parseColor("#F44336")

        val barDataSet1 = BarDataSet(barEntries1, "2")
        barDataSet1.setColors(Color.parseColor("#9C27B0"))

        val barDataSet2 = BarDataSet(barEntries2, "3")
        barDataSet1.setColors(Color.parseColor("#e241f4"))

        val barDataSet3 = BarDataSet(barEntries3, "4")
        barDataSet1.setColors(Color.parseColor("#42f46e"))

        val barDataSet4 = BarDataSet(barEntries4, "5")
        barDataSet1.setColors(Color.parseColor("#42f4ee"))

        val months = arrayOf("TYPE 1", "TYPE 2","TYPE 3","TYPE 4","TYPE 5")
        val data = BarData(barDataSet, barDataSet1, barDataSet2, barDataSet3,barDataSet4)
//        val data = BarData(barDataSet, barDataSet1)
        rootView.barChart.data = data

        val xAxis = rootView.barChart.xAxis
        xAxis.valueFormatter = IndexAxisValueFormatter(months)
        rootView.barChart?.axisLeft?.axisMinimum = 0F
        xAxis.position = XAxis.XAxisPosition.BOTTOM
        xAxis.granularity = 1f
        xAxis.setCenterAxisLabels(true)
        xAxis.isGranularityEnabled = true

        val groupSpace = 0.06f
        val barSpace = 0.02f // x2 dataset
        val barWidth = 0.45f

        //IMPORTANT *****
        data.barWidth = 0.15f
        rootView.barChart?.xAxis?.axisMinimum = 0F
//        rootView.barChart?.xAxis!!.axisMaximum = 0 + rootView.barChart.barData.getGroupWidth(groupSpace, barSpace) * groupCount
        rootView.barChart?.groupBars(0f, groupSpace, barSpace) // perform the "explicit" grouping

    }

}

任何人都可以帮我创建这种类型的水平滚动分组条形图

如果需要更多信息，请告诉我。提前致谢。我们将不胜感激。
