    Hi everyone,
    Do you know any code or algorithm to graph pie chart?
    I got phplot but its quality doesn't seem to be very good (although comparing to other script, it's very good, could tackle all kinds of graphs)

    If you know of a script, please let me know!
    Thanks

    This one http://www.vhconsultants.com/download.htm is free for personal usage.

    It can draw all kinds of graphs, about as smooth as i think it would be possible to be with GD libraries (practically speaking).

    Hope it helps

    Thanks mad-onion,
    Yeah, I checked it out, pretty good, but is it the limitation in quality of GD?

    Does anyone know how to anti-lias the circle?

    I've seen some dynamic-generated graphs with very good quality, but not sure if they reveal their technique!

    Buggered if i know how they manage to render them softly. Maybe there is a softening library for gd, or maybe they create the image bigger than it displays.

    Hmmm...
    There's a tutorial on http://www.devshed.com called stream me up scotty (2 parts, methinks) that has some good info on doing piecharts and stuff. Matter of fact, that's what the tutorial focuses on. Might wanna check it out?

    ... what's the world coming to?

    I just checked that article out and it's about files/directories.
    However, there is another article Image Generation talking about drawing stuff
    Thanks a lot

    What do you mean by creating the image bigger than it displays?
    Since I believe they have some technics like preparing the background (or whatever) before dynamically create the graphs.

    Thanks
