jqplot cannot display legend and y axis label correctly

Question

I have a linechart using jqplot with two lines. One line represents max values and other one represents min values. With my code legend does not display correctly and y axis label overlaps with y axis ticks What am I doing wrong? Thanks for your help!

[EDIT] Jqplot version is jquery.jqplot.1.0.0b2_r1012

My code displays this chart:

I want a legend like the one in this image

Here's my code:
