Adding data to the chart.

In this assignment, you will need to modify one of the 2 visualizations that are being used for the loan dashboard. This visualization is a 100% stacked column chart which measures the percentage of total payments going to interest and to principal.

The other visualization, measuring change in cumulative payments over time, is available for reference. You do not need to add the x-axis or change the title for this exercise.

It is important to capture references that show as #NUM! in the data range for the visualization, since the dashboard needs to be flexible enough to increase the number of possible periods. Removing the #NUM! references will be practiced in a later lesson.
