Hi, I saw you guys were actually pretty responsive in the forum! I am having an issue with rendering the chart.

I am doing a mysql query, thowing that data into an array, nothing special. I verified the arrays all have same length, no odd values etc.

When i attempt to render with autoput("test.png") the entire page breaks. Firefox says "The image 'asdf.php' cannot be displayed because it contains errors".

Iexplorer gives back some of the real text on the page then a big long PNG binary looking thing.

If i change to stroke() the rest of the page prints out except for the chart in both FF and IE

Hi,

This can occurs if your PHP script send text (maybe space) before the picture data. Basically your script must start by the <?php tag and end by the ?> tag, no space, nothing more before and after.

<?php
//get data from mysql
//do other page functions
?>

<?php
//all calls to plot,config,render data
?>

Would something like this work?

No! Because PHP will send empty strings to the browser that will break the image data. You have to write all you code in a single <?php ?> block.

im such an idiot....
<img src="chart.php">
im sorry!

I ran into this when I was copying one of the examples to play with it.

I made a plain HTML page that contains one img tag, and that img tag's source is the php page that generates the PNG.

In other words the PHP does not generate any HTML, it generates only the PNG.
