PHP: Help formatting Google (bar) charts

Question

Hi folks,

I'm trying to make a horizontal bar chart with data from an array

$values = implode(',', array_values($type));
$labels = implode('|', array_keys($type));
$img = "http://chart.apis.google.com/chart?cht=bhg&chs=600x300&chd=t:{$values}&chxt=x,y&chtt=Ticket+Types&chxl=1:{$labels}&chts=676767,21.5";
echo "<img src='{$img}' alt='Chart'>";

This isn't giving me what I want to achieve but I'm having a hard to fixing it. The code above gives me a horizontal bar chart with the y labels as the number of row (i.e. the first label is 1, the second label is 2) and incorrect x numbers.

I want the labels up the y axis and the values along the x.

Can someone give me a hand?

Answer 1

Hi,

I was trying to do pretty much same thing, last week. This was driving me crazy. Check out this OpenSource project, this is PHP interface for google charts

http://code.google.com/p/gchartphp/

Check out these examples page, you will be able to recreate your chart under a minute... http://code.google.com/p/gchartphp/wiki/Examples

This will make it much easier to develop and maintain.

I use GoogChart http://code.google.com/p/googchart/ and have modded it heavily to do what I need.
