## 获取和引入 XCharts
|
||
|
||
---
|
||
|
||
你可以通过以下两种方式获取 `XCharts` 。
|
||
|
||
如果你只是想运行 `Demo` 查看效果，可以在 [Github](https://github.com/monitor1394/unity-ugui-XCharts)上的 [Clone or download](https://github.com/monitor1394/unity-ugui-XCharts/archive/master.zip)下载最新版本或去 [release](https://github.com/monitor1394/unity-ugui-XCharts/releases)下载稳定版本，将源码工程解压后用`unity`打开即可。
|
||
|
||
如果你要将 `XCharts` 加入你的项目中，可以在[Github](https://github.com/monitor1394/unity-ugui-XCharts)上下载最新的 [release](https://github.com/monitor1394/unity-ugui-XCharts/releases)稳定版本，将 `XCharts-vx.x.x.unitypackage` 通过 Unity 导入到你的项目中，或下载 Source code 解压后将内部的 `XCharts` 文件夹拷贝到你项目的 `Assets` 目录下。
|
||
|
||
如果你是Unity 2018.3版本以上，强烈建议通过Package Manager来安装XCharts包，具体操作步骤如下：
|
||
|
||
1. 打开`Packages`目录下的`manifest.json`文件，在`dependencies`下加入：
|
||
```
|
||
"com.monitor1394.xcharts": "https://github.com/monitor1394/unity-ugui-XCharts.git#package",
|
||
```
|
||
2. 回到`Unity`，可能会花3到5分钟进行下载和编译，成功后就可以开始使用`XCharts`了。
|
||
3. 如果要删除`XCharts`，删除掉1步骤所加的内容即可。
|
||
4. 如果要更新`XCharts`，删除`manifest.json`文件的`lock`下的`com.monitor1394.xcharts`相关内容即会重新下载编译。在 `Component -> XCharts -> Check For Update`可以检测是否有新版本可更新。
|
||
|
||
## 添加一个简单图表
|
||
|
||
---
|
||
|
||
在`Hierarchy`试图下右键或菜单栏`GameObject`下拉：`XCharts->LineChart`：
|
||
|
||
即可快速创建一个简单的折线图出来：
|
||
|
||
在 `Inspector` 视图下可以调整各个组件的参数，`Game` 视图会实时反馈调整的效果。各个组件的详细参数说明可查阅[XCharts配置项手册](XCharts配置项手册.md)。
|
||
|
||
|
||
## 用代码添加折线图
|
||
|
||
---
|
||
|
||
给`gameObject`挂上`LineChart`脚本：
|
||
|
||
```C#
|
||
var chart = gameObject.GetComponent<LineChart>();
|
||
if (chart == null)
|
||
{
|
||
chart = gameObject.AddComponent<LineChart>();
|
||
}
|
||
```
|
||
|
||
设置标题：
|
||
|
||
```C#
|
||
chart.title.show = true;
|
||
chart.title.text = "Line Simple";
|
||
```
|
||
|
||
设置提示框和图例是否显示：
|
||
|
||
```C#
|
||
chart.tooltip.show = true;
|
||
chart.legend.show = false;
|
||
```
|
||
|
||
设置是否使用双坐标轴和坐标轴类型：
|
||
|
||
```C#
|
||
chart.xAxises[0].show = true;
|
||
chart.xAxises[1].show = false;
|
||
chart.yAxises[0].show = true;
|
||
chart.yAxises[1].show = false;
|
||
chart.xAxises[0].type = Axis.AxisType.Category;
|
||
chart.yAxises[0].type = Axis.AxisType.Value;
|
||
```
|
||
|
||
设置坐标轴分割线：
|
||
|
||
```C#
|
||
chart.xAxises[0].splitNumber = 10;
|
||
chart.xAxises[0].boundaryGap = true;
|
||
```
|
||
|
||
清空数据，添加`Line`类型的`Serie`用于接收数据：
|
||
|
||
```C#
|
||
chart.RemoveData();
|
||
chart.AddSerie(SerieType.Line);
|
||
```
|
||
|
||
添加10个数据：
|
||
|
||
```C#
|
||
for (int i = 0; i < 10; i++)
|
||
{
|
||
chart.AddXAxisData("x" + i);
|
||
chart.AddData(0, Random.Range(10, 20));
|
||
}
|
||
```
|
||
|
||
这样一个简单的折线图就出来了：
|
||
|
||
|
||
完整代码请查阅`Demo`：`Demo13_LineSimple.cs`
|
||
你还可以用代码控制更多的参数，[XCharts配置项手册](XCharts配置项手册.md)里面的所有参数都是可以通过代码控制的。
