=Ruby Free Chart - Basic Ruby wrapper for JFreeChart

The RubyFreeChart is a wrapper for JFreeChart, a Java chart library that makes it easy for developers to display professional quality charts in their applications.

RubyFreeChart is an alternative for projects that for some reason cannot use JRuby and need to display data in high quality charts.

Currently, the only supported type of chart is a very small subset of the Pie Chart.

==Usage

   pie_chart = RubyFreeChart::PieChart.new

   pie_chart.title = "Cars by Color"

   pie_chart.width = 450

   pie_chart.height = 300

   

   pie_chart.add_value("Yellow", 87, "#FFFF00")

   pie_chart.add_value("Red", 34, "#FF0000")

   pie_chart.add_value("Black", 45, "#000")

   pie_chart.add_value("Blue", 60, "#0033CC")

   pie_chart.add_value("Green", 14, "#336633")

   pie_chart.render_png_to_file("test_chart.png")
