[gochart](https://github.com/zieckey/gochart) is a chart ploting tool which is simple to use. It used the open sources [golang](https://golang.org) and [highcharts](http://www.highcharts.com) which is modeled after [goplot](https://github.com/skoo87/goplot). It can plot spline/line/area/bar/column/pie. This tool is just a binary independent with any other lib or environment.

||
|
||
### Example 1 : Spline data format
|
||
|
||
This data format can be also used to plot line/bar/column/area when you can change the value of `ChartType`. The option value of `ChartType` is below :
|
||
|
||
- spline
|
||
- line
|
||
- bar
|
||
- column
|
||
- area
|
||
|
||
```go
|
||
# The chart type , option : spline/line/bar/column/area
|
||
ChartType = spline
|
||
Title = Source: WorldClimate.com
|
||
SubTitle = Monthly Average Temperature
|
||
ValueSuffix = °C
|
||
|
||
# The height (px) of the chart
|
||
Height = 400
|
||
|
||
# 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
|
||
Data|Tokyo = 7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6
|
||
Data|New York = -0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5
|
||
Data|Berlin = -0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0

|
||
```
|
||
|

### Example 1 : Pie chart
|
||
|
||
```go
|
||
ChartType = pie
|

Title = Browser market shares at a specific website, 2014
|
||
SubTitle = from website.com
|
||
SeriesName = Browser shares

|
||
Data|Firefox = 45.0
|
||
Data|IE = 26.8
|

||
Data|Opera = 6.2
