* Constructor for graph window
* Goes through the values in both the income and expenses lists associated with the current user
* plots datapoints on two separate graphs depending on which list they come from
*
* May want to update the X axis in the future. Currently the x axis doesn't really make much sense to a lay person
* but the income x-axis is used for pay periods. The x-axis for expenses should just sync up with the income axis.
* The expenses x-axis is number of expenditures during the number of pay periods listed in the income graph x-axis
