hi,

i have an array of data and i would make a graph to illustrate them.

the array is a collection of number of users who have a number of

freinds between eg: 1-10 then 10 - 20 … User.last.id

nbr of freinds | nbr users |

 1-10         |       2           |

 11-20       |       5           |

  21-50      |       10         |

  51-70      |       26         |

…

…

its possible to make something like:

51-70| *

    >

21-50| *

    >

11-20| *

    >

01-10| *

    >__________________________________

    0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 .....

but the * are related.

thanks

use google graphs and the seer gem.

Open Flash Charts used to be a very good choice. Worth having a look
to see if it does what you need.

I prefer flot which uses javascript rather than flash and works well
for me. Much quicker loading charts with lots of data.
