This is the code I used to make a barchart that displays the outcome of a
few polls. For some reason the chart doesn't show. I've tried several
things such as just putting numbers in the chart which worked in a
different php file but didn't in this file. I have no idea what to do now
and I would greatly appreciate it if someone is able to help me.
