Creating a line graph in jqplot

I have a piece of code here that should create a line graph consisting of two lines. It will not render the lines and neither the dates on the x-axis. The y-axis is apparently already scaled for the y-values, so the data interpretation went correctly for at least some of the data.
Does anybody see an immediate solution to having the lines displayed as well as the dates along the x-axis?

source01 = [

SOLVED: Requires the following additional file to work:
