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

	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.height = 200
	sales_chart.width = 150
	
	#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 = 600
	sales_chart.width = 350
	big_sales_chart_url = sales_chart.to_url
