Control the forecast duration & address graph scale

Ability to control the CFF duration.

Pain points:

• Want to see forecasted total amounts at week intervals

• With a longer time frame the graph can show "too" much, as the time frame extends the accuracy of the forecast declines. The ability to restrict there helps users see "better" data only

Could we use this starting field to update the duration? I never understood why this had a calendar icon without any functionality.

Scale notes: Currently, the lowest value and highest value on the graph on based on the lowest forecasted value and highest forecasted value over the longest period (6 months). Typically, the forecast has predictions fall off after a certain number of months, causing the forecast to drop after a few months. When using a daily/weekly view, it causes the scale to be off, making the data get scrunched and more difficult to read. The scale of the graph should be based on the filter for daily/weekly/monthly.
