如何使用MPAndroidChart创建多个堆积条形图？

Question

这里是json，我想显示与MPAndroidChart library 一起显示的图表。

[
    {
        "MonthName": "February",
        "Year": "2016",
        "IssuesCount": 3,
        "ClientName": "A",
        "IssueStatus": "Total",

    },
    {
        "MonthName": "February",
        "Year": "2016",
        "IssuesCount": 13,
        "ClientName": "B",
        "IssueStatus": "Total",

    },
    {
        "MonthName": "February",
        "Year": "2016",
        "IssuesCount": 1,
        "ClientName": "A",
        "IssueStatus": "Closed",

    },
    {
        "MonthName": "February",
        "Year": "2016",
        "IssuesCount": 2,
        "ClientName": "B",
        "IssueStatus": "Closed",

    },
    {
        "MonthName": "February",
        "Year": "2016",
        "IssuesCount": 1,
        "ClientName": "A",
        "IssueStatus": "OutStanding",

    },
    {
        "MonthName": "February",
        "Year": "2016",
        "IssuesCount": 10,
        "ClientName": "B",
        "IssueStatus": "OutStanding",

    },
    {
        "MonthName": "March",
        "Year": "2016",
        "IssuesCount": 1,
        "ClientName": "A",
        "IssueStatus": "OutStanding",

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

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

    {
        "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，请建议如何继续这样做。我很难将特定月份的详细信息分组并显示单个月的多个条形图。

Answer 1

这是可能的。

你需要什么：

• 1 BarData个对象，填充：
• 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了堆叠的BarEntries
• ＆＃34; bar-groups＆＃34;之间的空间。可以通过barData.setGroupSpace(...)
设置
• 可以通过barDataSet.setBarSpace(...)
设置各个条之间的空格

可以像这样创建堆叠的BarEntry：

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创建的图表就像您在上图中显示的图表一样。
