Drawing circles in php

[Paul Charlton-Thomson]

Hi,

I am passing 8 values each from 1 to 10 to a php page and at the moment I am
drawing a bar chart using shaded cells to represent the magnitude of each
bar.

I would also like to draw these values into a pie chart ... can anyone tell
me if this is possible? If so can you point me to some example code?

Help appreciated.

Paul.

I doubt there's any built-in pie-chart functions in PHP, but it's not
hard to draw your own.

Sorry, I didn't finish what I was gonna say!

There's functions such as imagefilledarc( ), which would probably be
enough to do what you want.

Re: Drawing circles in php

I second jpgraph. It's an excellent php library for drawing all kinds
of graphs. It's also pretty popular, so you would get good support from
users and chances are it might already be on the server.

Thanks,

Sadly I have been upgraded to PHP5 and JpGraph doesn't work with 5.0

Have got it working with GD2.0 in PHP5 :-)

Read this :

http://www.aditus.nu/jpgraph/jpdownload.php

" Note: The 2.x series is only for PHP5. It will not work on PHP4 "

Doesn't work with PHP 5 ??!!
