One small note: The last line (return $chartData.”&chxt=y&chxl=0:|0|”.$maxValue; — which puts a scale on the axis) assumes a vertical orientation. Anyone interested in a graph with horizontal orientation (ie bhs or bhg) should write chxt=x instead of chxt=y to get the desired graph.

Nice work!

Can I just ask – I’ve used your code in a dynamcially generated HTML table (now with chart!) but I’m having difficulties loading my string into the array of your code i.e.

$test_data=array(0.5,6,12,17,2,0.3,9);

becomes

$string1 =”0.5,6,12,17,2,0.3,9″
$test_data=array($string1);

My string is being created at the same time as the table and echoing the data gives a result of 0.5,6,12,17,2,0.3,9 and the max value is also 0.5,6,12,17,2,0.3,9 but no data??

Any suggestions?

Thanks

The charts *are* very pretty though..

Yes, everyone’s using Google Maps these days, but I just wonder how many “large” or “critical” sites would be prepared to risk this (there’s a 50,000 queries per day limit.)

Sorry to be boring.

I had a very basic look/play with it, don’t know whether it can help but looks quite good. http://www.swivel.com/

Thanks for the code!

What I don’t like about Google chart API is the fact axis don’t have nothing to do with values.

Thus, in order for a simple x,y graph to make sense, you have to find the percentage of all your values and then plot them. I mean, if your max value is 150, you must make 150=100% and then calculate all values below it in terms of percentage. Your laber on the x axe will be 150, but your value will be 100%.

I wonder who will be the first to do a PHP class to do this…

Also: it does not work on forums with the [IMG] tag…
It would be usefull for the PHP class to load the url as binary and outputs it as .png, so that it can be recognized everywhere.
