Creating graphs in php?

[matthewhaworth]

Has it been done before and is it possible?

[trq]

Yes, and yes.

Graphs are maths!  I do not see why my thread was moved.

because you're going to need more help with GD commands than math (or so whoever moved it thought - I tend to agree)

There are a lot of tutorials out there, but basically there are abotu 5-6 steps to making line graphs

 

step 1 Draw a shape (define the area with a box/gridlines)

step 2 Generate an array of values i.e ($nodes = array(1,4,6,2,3,5,7,65,2,34,1,23,)

this array is going to be graphed with respect to their array index.  This is like saying each point was say a server load in mb at a given time taken at uniform intervals

step 3 a step distance ( i.e nodes/width of graph-20 pixel (padding));

step 4 now this is the tricky part the way you do this is with a dual counter function so basically you are drawing a point from $nodes[$i] to $nodes[$j] where $j = $i +1;  The second trick to this is you need to know your spacing based on step 3 for you x distance and your Y distance is the 2 nodes

step 5 add on extras/tweak it to your needs.

Look at some of the tutorials on this website. I've not personally tested them but they seem to look pretty good. Specifically the one about jpgraph.
