    {
        "MonthName": "March",
        "Year": "2016",
        "IssuesCount": 0,
        "ClientName": "B",
        "IssueStatus": "Closed",

    },
    {
        "MonthName": "March",
        "Year": "2016",
        "IssuesCount": 3,
        "ClientName": "A",
        "IssueStatus": "Total",

    },
    {
        "MonthName": "March",
        "Year": "2016",
        "IssuesCount": 9,
        "ClientName": "B",
        "IssueStatus": "Total",

    }
]

我正在使用 MPAndroidChart 库，请建议如何进行。我很难对特定月份的详细信息进行分组并显示单个月份的多个条形图。

这是可能的。

你需要什么:

• 1 个 BarData 对象，填充有:
• 3 个数据集(一个用于红色条，一个用于紫色，...)
• 并且每个数据集都填充有堆叠的BarEntries
• 可以通过barData.setGroupSpace(...)设置“bar-groups”之间的空间
• 可以通过 barDataSet.setBarSpace(...)
设置各个条之间的间距

堆叠式 BarEntry 可以这样创建:

new BarEntry(new float[] { stackvalue1, stackvalue2 }, xIndex);

xIndex 对应于条目应映射到的 x 轴上的月份(在您的情况下)。

This example创建一个与您在上图中显示的图表一样的图表。
