gochart仿照[goplot](https://github.com/skoo87/goplot)使用golang和[highcharts](http://www.highcharts.com)开源库制作的，是一个使用简单的绘制图表的工具，图表风格有曲线图、折线图、面积图、柱状图、饼图等。编译好的gochart只有一个二进制文件，不依赖任何库/网络。

|
##### 使用方法
|
|
|
|
|
|
|
|
|
|
|
|
* 解压下载包后，进入解压目录，可以看到一个gochart的可执行文件和一些*.chart文件，这些chart文件是默认的一些数据文件样例。可以在这些chart文件的目录执行gochart，然后通过浏览器访问http://localhost:8000就可以看到图表了。
|

|
|
|
|
* 可以把`gochart`工具放到您的`PATH`中，在*.chart文件所在的目录执行gochart即可。
|

|
|
|
|
* chart文件必须是.chart后缀名，内容可以参考源码examples目录中的例子。启动gochart的目录如果有多个chart文件，可以通过不断刷新网页来切换图表。

Title = Source: WorldClimate.com
|

SubTitle = Monthly Average Temperature
|

ValueSuffix = °C
|
|
|
|
|
|
|
|
|
|
|
|
# The x Axis numbers. The count this numbers MUST be the same with the data series
|
|
|
|
|
|
XAxisNumbers = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12
|
|
|
|
|
|
|
|
|
|
|
|
# The y Axis text
|
|
|
|
|
|
YAxisText = Temperature (°C)
|
|

# The data and the name of the lines

该示例数据格式与曲线图、折线图、面积图、(横向/纵向)柱状图通用。通过改变`ChartType`可以展现不同类型的图，如下：
|
|
|
|
|
|
- spline 曲线图
|
|
|
|
|
|
- line 折线图
|
|
|
|
|
|
- bar 横向柱状图
|
|
|
|
|
|
- column 纵向柱状图
|
|
|
|
|
|
- area 面积图
|
