Re: [PHP] Graph Question..
Jim, Regarding "undefined function: imagegif()," It could be that your build of the "GD Library" doesn't include gif support. You can try replacing this function with imagejpg() or imagepng(). Imagepng() will likely be faster and sharper than imagejpg().

Re: [PHP] Graph Question..
Jim, on the calling page change echo "\n"; to echo "something here\n"; Now, when you click on the link, the error message should show instead of the broken box.

RE: [PHP] Graph Question..
What I'm wondering is if you are calling the graphic's placing into the page correctly. I believe the class will probably work. I have a page that includes a graph that I generate using mySQL and PHP. This is the code I use to actually display the graphic (not what generates it). ImageJPEG($pic,$graphname); echo "\n"; Of course there is a significant amount of code that actually generates $pic, but this is what I had to do to make the graphic appear.

Re: [PHP] Graph Question..
Try going direct to the image's URL, this might show any PHP errors. If that doesn't work, you can request the page via telnet and see if any errors are appearing Andrew - Original Message - From: "James Hatridge" <[EMAIL PROTECTED]> To: "PHP-GEN" <[EMAIL PROTECTED]> Sent: Wednesday, November 20, 2002 3:06 PM Subject: [PHP] Graph Question..

More information would be helpful. Perhaps the code to the page that is causing you trouble (i.e. the one where you are using the class you downloaded yesterday).
