Looking for example to send graph direct to browser

Post by kragero60 » Tue Jan 06, 2015 3:49 pm

The demos show a .png file being created. How do avoid that and send the graph to the browser without creating a .png file?

Hello,

The charts in TeeChart PHP must be created at server-side but instead of creating a png as follows:

Code: Select all

$chart->render("chart1.png"); 
You can directly send the stream calling the same function without parameters:

Code: Select all

$chart->render();

Hi,

Thanks for the reply. If I try that I get the following error message.

Fatal error: Call to undefined function imageftbbox() in /usr/local/uptime/GUI/teeChart/sources/GraphicsGD.php on line 2504

I need to have teeChart in a slightly unusual location... Do I have to do something special for that?

Hello Randy,

Many apologies for the delayed reply.

Find attached an example calling render() without parameters and sending the chart to the browser as a stream. Hope this solves the problem at your end.
