 ## 为什么升级到1_6_0版本后很多自定义颜色丢失了_应该如何升级

-答：1.6.0版本为了减少隐式转换，将所有的绘制相关的`Color`都改为了`Color32`，所以会导致一些自定义的颜色的丢失。影响到的主要组件有：`ItemStyle`，`LineStyle`，`AreaStyle`，`Vessel`，`VisualMap`，`AxisSplitArea`，`AxisSplitLine`，`GaugeAxis`，`SerieLabel`等。可以用脚本[UpgradeChartColor.cs](https://github.com/monitor1394/unity-ugui-XCharts/blob/master/Assets/XCharts/Editor/Tools/UpgradeChartColor.cs)进行升级。

 3. 若是由`itemStyle.toColor2`引起的编译报错，可将导出地方的`itemStyle.toColor2`改为`Color.clear`；导入的地方注释掉即可。
 4. 若是由`LiquidChart`引起的编译报错，将所有涉及`LiquidChart`的地方都注释掉即可。
 5. 编译通过后，通过`菜单栏->XCharts->ExportColorConfig`导出旧版本的颜色配置文件（配置文件默认保存到`Assets`下的`color.config`）。

 3. After compilation, the old version of color configuration file is exported through `menu bar -> XCharts-> ExportColorConfig` (the configuration file is saved by default to `color.config` under `Assets`).
 4. Upgrade `XCharts` to the latest version.
 5. The custom color can be restored by importing `color.config` through `menu bar -> XCharts-> ImportColorConfig` (if `color.config` is not under `Assets` of the upgraded project, copy it to this directory).

Kermit	2d3f5dd51d	Update XChartsMgr.cs 修复因XChartsMgr不存在，而创建新对象时导致的死循环问题。由于Awake会在组件被创建时同步执行一次，而在执行Awake时m_XCharts并没有被赋值，所以导致死循环。让对象处于关闭状态，添加组件时就不会同步执行Awake方法，而是延迟到下一次开启对象时执行。在下一次开启对象时，m_XCharts已经被赋值，所以不会导致死循环问题。死循环发生在Awake时调用XThemeMgr.ReloadThemeList，而ReloadThemeList方法中有调用了实例。	2022-04-08 14:12:15 +08:00
