Hi, guys!

I have got a problem. I tried to output graphs in loop, but only the first graph is outputted.
How to solve my problem? =)
Code:
for ($i=0;$i<count($arr);$i++)
{
$MyData = new pData();
...

$myPicture->autoOutput("pictures/google_get".$poss_bd[$i].".png");
}

Hi,

Is this script called from a web browser or a server command line?

First I would advice to use the render() function to create the files (but it will not solve the issue):

Code:
$myPicture->render("pictures/google_get".$poss_bd[$i].".png");


Then you must ensure that your script isn't stuck anywhere and that the file name really change by adding some echos. There is no limitation on the number of charts generated by a script files. (I'm using a daemonized PHP script that generate hundred of pictures)
