+ * An AccountingSerie displays plottable, aggregated balance data over a time range for a given Accounting.\
+ * \
+ * AccountingSeries are calculated in real-time for each request from the available data for the Accountings,
+ * each data point is a Money object representing the aggregated balance of the Accounting at that point in the serie.\
+ * \
+ * Data points are relative to the series and do not relate to any specific unit of time.\
+ * You might get data points for specific days when you make the `maxLength` match the number of days in your date range,
+ * but the behaviour is not guaranteed and data points might be less than your desired output if there is not enough data.
