Hello, I''m testing Google Charts API plugin for rails and have a few questions about it''s use (I searched for a developper documentation for about an hour without founding anything really interesting): Here is my test code: # Testing google charts api chart = GoogleChart.new chart.type = :bar_vertical_stacked chart.height = 400 chart.width = 600 chart.data = [@totalAmount, @totalPercent] chart.colors = ''346090'' chart.labels = ["total", "percent"] @small_sales_chart_url = chart.to_url And in the view: <%= image_tag @small_sales_chart_url %> The generated graph url is: http://chart.apis.google.com/chart?chs=600x400&cht=bvs&chco=346090&chl=total|percent&chd=t:300.0,100.0 This is great, but I would like to know how to: - Set the space between each bar - Define the y axis labels - Create a bar with values that can be negative - Write the value of each bar directly on the graph ....and so many more. If anyone knows where I could find a complete developper guide that would be great, if not maybe you can help me with those few questions in the meantime.
