How to create SVGGraph with thin bars on a wide grid?

Question

I am using PHP SVGGraph to build a graph. I have a graph that currently looks like this:

What I would like to do is keep the width of the grid the same but the bars should not be so wide. I am not able to find anything in the docs on whether this can be done.

Is it possible to do this?

Answer 1

According to documentation you adjust the width of the bars using the options parameter when creating the instance:

// Notice the 3 argument
$graph = new SVGGraph(640, 480,array("bar_width"=>'100'));

Referenced from the options page (near the bottom):
