Assignment 6a - Section 1.6 - Missing parameters and labels

[G0rocks]

The _plot_j() function has no input variables meaning the only way to make it is to use global variables which is not in line with coding best practices.

Also, in the example plot the axis are not labeled which is not in line with graph standard practices, all axis should be labeled.

Actions:

• Add J and iters or similar as input parameters to the _plot_j() function
• Label axis on example graph
