GoogleChartsOnRails

This is a very small wrapper plugin for the wonderful Charts API from Google.

Example

GoogleChart.pie(10,20,40,30).to_url

With labels:

GoogleChart.pie(['1997',10],['1998',20],['1999',40],['2000',30]).to_url

or with a Hash

GoogleChart.pie('year 1997'=>10,'year 1998'=>20,'year 1999'=>15,'year 2000'=>55).to_url

Pretty much anything would work:

GoogleChart.line_xy 
GoogleChart.bar_horizontal_stacked
GoogleChart.bar_vertical_stacked
GoogleChart.bar_horizontal_grouped
GoogleChart.bar_vertical_grouped
GoogleChart.pie
GoogleChart.pie_3d 
GoogleChart.venn
GoogleChart.scatter_plot

which you can marry with the size as x

GoogleChart.pie_100x200(10,20,40,30).to_url

even

GoogleChart.100x200_pie(10,20,40,30).to_url

or do as crazy as

GoogleChart.pie_with_size_blah_blah_600x400('year 1997'=>10,'year 1998'=>20,'year 1999'=>15,'year 2000'=>55).to_url

Lets do it the old fashioned way:

sales_chart = GoogleChart.new
sales_chart.type = :pie
sales_chart.data = [10, 20, 15, 55]

sales_chart.width = 150
sales_chart.height = 200

#change the default colour with the hex code
sales_chart.colors = '346090'

small_sales_chart_url = sales_chart.to_url

#reuse and change size, set labels for big chart
sales_chart.labels = ['year 1997','year 1998','year 1999','year 2000']
sales_chart.height = 350
sales_chart.width = 600
sales_chart.title = "Sales Chart"
big_sales_chart_url = sales_chart.to_url
