This section allows you to see the balance of your current account over time. It is a line graph (or area chart to be specific), with your balance shown on the left axis and date on the bottom axis. To read it, simply look at the height of the blue line that is directly above the date you want to look at.

By using the tracker circle on the graph, you can pick any date along the line and see the transactions that occurred at that period in time. This might help you understand why your graph went up or down at certain times. As an example, the line may increase drastically if you sell a car, but may go down drastically if you buy a car.
