Some news

Open Flash Chart Lazy now requires Mhash

gem sources -a http://gems.github.com
sudo gem install peterpunk-mhash

This is helpful to set the parameters as methods.

Before you have to set:

#previous version
bar_chart.y_axis[:min]=0
bar_chart.y_axis[:max]=1000
bar_chart.y_axis[:steps]=100

With the new version, is compatible with previous but if you fill confortable you can set the values as standard methods. But remember that some non-standard name parameters as "grid-colour" will still be setted as previous ["grid-colour"]

#new version
bar_chart.y_axis.min=0
bar_chart.y_axis.max=1000
bar_chart.y_axis[:steps]=100
# or 
bar_chart.y_axis.steps=100

Also the new beta version of Open Flash Chart Alpha8 is now embbeded.

Enjoy

What is

Is a ruby library to use open_flash_chart2 movie to show charts in your application. Is compatible with Ruby on Rails and Sinatra (this sample is built on sinatra).

The code not reproduce all the objects of the ofc library, just the minimal to get it configured and working as easy as possible.

Was designed to make simple to use and extend.

Creating the first chart

All of the charts are based on a helper object called Serie

A serie could be created with an array or hash, and the series could be time based or label based.

Label based

Is the most simple serie, could be a hash or array

#label based
data=[['funky',200],['punky',300],['jazzy',120]]
serie = OpenFlashChartLazy::Serie.new(data)

Time based

You can define a start date and a number of periods (months by now)

#time based
data=[['2008-1',200],['2008-2',300],['2008-3',120]]
serie = OpenFlashChartLazy::Serie.new(data,{:start_time=>Time.mktime(2008,1,1),:items=>4})

Bar 3d Sample (new)

  income = [["tv",40000],["internet",10000],["magazines",50000],["other",40000]]
  bar_chart = OpenFlashChartLazy::Bar3d.new("Income")
  topics=OpenFlashChartLazy::Serie.new(income,{:title=>"Media"})
  bar_chart.add_serie(topics)
  bar_chart.bg_colour="#FFFFFF"

  bar_chart.x_axis.colour="#808080"
  bar_chart.x_axis["grid-colour"]="#A0A0A0"
  # add this setting here because will be placed first to work
  bar_chart.x_axis["3d"]=10

  bar_chart.y_axis.colour="#808080"
  bar_chart.y_axis["grid-colour"]="#A0A0A0"
  bar_chart.y_axis.min=0
  bar_chart.y_axis.max=80000
  bar_chart.y_axis.steps=25000
  
  #adding tip an color to a bar
  bar_chart.elements.last.values[2]={"top"=> income[2][1], "colour"=> "#D54C78",:tip=>"look here"}
  
  bar_chart.to_json

Pie Sample

  penetration = [["tv",40],["internet",10],["magazines",50]]
  pie_chart = OpenFlashChartLazy::Pie.new("Media")
  serie=OpenFlashChartLazy::Serie.new(penetration)
  pie_chart.add_serie(serie)
  pie_chart.title.text="My Chocolate Pie"
  pie_chart.title.style="{background-color:#000000;color:#ffffff;font-size:20px;}"
  pie_chart.bg_colour="#FFFFFF"

  bar_chart.add_serie(topics)
