Hi...
I am trying to debug an erro i receive using JPgraph.
The error is:
"Illegal Pie Plot - SUm of all data is zero for pie".
Ok, I understand what it says, but where or what do i do to learn more?
Does it mean that the values returned from my sql select is NUll?
thx

I've just started using jpgraph myself, and I've found the forums and documentation there extremely valuable. I'd check out the documentation to get a further explanation to the error.
Also, dump the results of your query to see if what happens is actually what you think is happening.

Real programmers don't comment their code. If it was hard to write, it should be hard to understand.
