Java 条形图中的数据集在MpAndroidChart中绘制错误

我正在使用MPAndroidChart绘制条形图。我有以下数据集：

DataSet, label: LABEL 0, entries: 21

[Entry, x: 1.0 y: 21.0],[Entry, x: 2.0 y: 10.0],
[Entry, x: 3.0 y: 19.0],[Entry, x: 4.0 y: 10.0],
[Entry, x: 5.0 y: 11.0],[Entry, x: 6.0 y: 14.0],
[Entry, x: 7.0 y: 11.0],[Entry, x: 8.0 y: 16.0],
[Entry, x: 9.0 y: 16.0],[Entry, x: 10.0 y: 8.0],
[Entry, x: 11.0 y: 10.0],[Entry, x: 12.0 y: 16.0],
[Entry, x: 13.0 y: 16.0],[Entry, x: 14.0 y: 12.0],
[Entry, x: 15.0 y: 17.0],[Entry, x: 16.0 y: 15.0],
[Entry, x: 17.0 y: 7.0],[Entry, x: 18.0 y: 17.0],
[Entry, x: 19.0 y: 10.0],[Entry, x: 20.0 y: 9.0],[Entry, x: 21.0 y: 10.0]

DataSet, label: LABEL 1, entries: 5
[Entry, x: 1.0 y: 1.0],
[Entry, x: 2.0 y: 1.0],
[Entry, x: 3.0 y: 1.0],
[Entry, x: 8.0 y: 4.0], 
[Entry, x: 11.0 y: 1.0] 

DataSet, label: LABEL 2, entries: 21
[Entry, x: 1.0 y: 57.0],[Entry, x: 2.0 y: 88.0],
[Entry, x: 3.0 y: 72.0],[Entry, x: 4.0 y: 82.0],
[Entry, x: 5.0 y: 84.0],[Entry, x: 6.0 y: 74.0],
[Entry, x: 7.0 y: 72.0],[Entry, x: 8.0 y: 82.0],
[Entry, x: 9.0 y: 66.0],[Entry, x: 10.0 y: 57.0],
[Entry, x: 11.0 y: 51.0],[Entry, x: 12.0 y: 44.0],
[Entry, x: 13.0 y: 52.0],[Entry, x: 14.0 y: 52.0],
[Entry, x: 15.0 y: 58.0],[Entry, x: 16.0 y: 53.0],
[Entry, x: 17.0 y: 54.0],[Entry, x: 18.0 y: 47.0],
[Entry, x: 19.0 y: 58.0],[Entry, x: 20.0 y: 60.0],[Entry, x: 21.0 y: 2.0]

以下是绘制错误的条形图的图像

在上图中，值的绘制不正确。请看数据集2，它有5个条目，其中x值[4,5,6,7]不存在，但在连续绘制的图形中，我在set1和set3中有21个条目。当绘制此数据时，仅为set 1绘制了15条记录，为set 3绘制了14条记录

我尝试了很多方法，有人能告诉我是否可以绘制这种数据集吗
