I think it would be best to define what we'll test. For instance, firstly we should make sure the core file: jqplot.core.js has a good test coverage. The file currently consists of multiple classes; we should create test cases for each class.

jqplot.core.js classes

• [ ] JqPlot()
• [ ] Axis()
• [ ] Legend()
• [ ] Title()
• [ ] Series()
• [ ] Grid()

jqplot.core.js - jQuery - functions

• [ ] $.fn.emptyForce
• [ ] $.fn.removeChildForce
• [ ] $.fn.jqplot

Functions

• [ ] checkIntersection
