Discussion

I like this feature very much, but I wanted charts to resize with the browser and not to impose a fixed width chart on visitors. Also, I wanted to display the real value next to the percentage in my charts. To implement those changes I made two small modifications to the code. First, I set the table width to 90%,

<table width='90%' class='graph' cellspacing='6' cellpadding='0'>

and then rewrote the code drawing the bars as follows,

<td width='%(width1)s'>%(name)s</td><td width='%(width2)s' class='bar'><div style='width: %(value)s'></div>%(value)s %(value2)s</td></tr>""" % {
"width1": '25%',
"width2": '75%',
"name": name,
"value": str(round((float(value)/sum) * 100, 1))+'%',
"value2": '('+str(value)+')',
}

where width1 and width2 set the 1st (names) and 2nd (values) column width, and value2 is used to display the actual value in parentheses after the percentage.

• please see r371. It embeds the chart in a div tag. So it does not destroy the page layout anymore. Thanks for the idea!
