Thanks for your help, I used the stroke method instead.
It’s working for me, as I just need to display it.

Still would like to know where things are going wrong with Render()..

Thanks ans Regards

that’s what i did.
I have hard-coded the filename but canont see the output.
When I am calling the render function without any arguments, it does return the binaries but when I pass the filename, no output is there…

and what’s the following code doing?
# $webPrintStr = <<<
#
# ETEXT;
#
# echo $webPrintStr;

Ashish,
You can give it any name you want.

I have defined it as $chartFileName = $_SERVER['REQUEST_TIME'].”_testChart.png”; just to generate a random file every time. You can also hardcode the filename and probably use it in a different section of the application to display the PNG. The charting engine generates the PNG file so you don’t necessarily need to create it before-hand, just ensure that the file and/or its folder has enough permission to create and write files

Regards,
Krishna

can you please explain what is this chatfilename, do i need to pass an already created png file or it will be generated itself?? if I need a png file beforehand, where should i keep it then?
and all this code is part of index.php?
if not, where should i keep it, should it be inside charting-test??

Good work! Thank you very much!
I always wanted to write in my blog something like that. Can I take part of your post to my blog?
Of course, I will add backlink?
