 ## FAQ

   答：`XCharts`使用`MIT`协议，可以免费使用。也可以订阅`VIP`享受更多增值服务。

 2. `XCharts`支持代码动态添加和修改数据吗？支持从`Excel`或数据库中获取数据吗？  
-   答：支持代码动态添加和修改数据，但数据需要自己解析或获取，再调用`XCharts`的接口添加到`XCharts`。
+   答：`XCharts`提供了各种数据操作的接口，支持代码动态添加和修改数据，但数据需要自己解析或获取，再调用`XCharts`的接口添加到`XCharts`。

 3. 这个插件除了用在`Unity`，还能用在其他平台（如`Winform`或`WPF`）吗？  
   答：目前只支持在`Unity`平台使用。理论上任何支持`UGUI`的`Unity`版本都能运行`XCharts`。

+4. 锯齿怎么解决？支持多大量级的数据？  
+   答：`XCharts`是基于`UGUI`实现的，所以`UGUI`中碰到的问题，在`XCharts`中也会存在。比如锯齿问题，比如`Mesh`顶点数超`65535`的问题。这两个问题的解决可参考`问答16`和`问答27`。  
+   由于`Mesh`的`65535`顶点数的限制，目前`XCharts`的单条`Line`大概支持`2万`左右的数据量，当然开采样可以支持更多数据，但可能会更消耗CPU。
