请教XField是datetime类型，有时分秒，应如何显示？

数据示例：
datetime:{2019-05-13 14:00:00 , 2019-05-13 14:30:00 , 2019-05-13 15:00:00}
value:{111,222,333}

配置文件这样写：
```
LineConfig config = new LineConfig()
{
Title = new AntDesign.Charts.Title()
{
Visible = true,
Text = "曲线折线图",
},
Description = new AntDesign.Charts.Description()
{
Visible = true,
Text = "用平滑的曲线代替折线。",
},
Padding = "auto",
ForceFit = true,
XField = "datetime",
YField = "value"
};
```

``

页面上始终不显示图表，请问是日期时间类型的数据不支持吗？应如何处理呢？谢谢
