Go utility for converting JSON data type to Google Chart structure so that DataTable can understand.

This utility export the types needed for creating Data Parameters needed to draw the chart

Examples

1. Import Chart

   import (
       GoogleChart "github.com/prabdeb/go-google-chart"
   )
   

2. Initiate the chart object with Columns

   zooData := GoogleChart.Chart{
       Cols: []GoogleChart.ColsType{
           GoogleChart.ColsType{
               Label: "Animals",
               Type:  "string",
           },
           GoogleChart.ColsType{
               Label: "Count",
               Type:  "number",
           },
       },
   }
   

3. Insert into Rows

   for animal, count := range zooDatabase["zoo_name"].(map[string]interface{}) {
       zooData.Rows = append(zooData.Rows, GoogleChart.RowType{
           C: []GoogleChart.RowCType{
               GoogleChart.RowCType{
                   V: animal,
               },
               GoogleChart.RowCType{
                   V: count,
               },
           },
       })
   }
