Scrolling forward and backward in time on the time slider
You can scroll backward and forward in time using the Scroll back and Scroll forward buttons on the Time Slider window. These buttons are not available when the time extent of the time slider, which is defined by the Start time and End time values, is set to the full time extent. However, when you modify Start time and End time of the time slider such that you are focusing on a time extent that is less than the full time extent of the time slider, the Scroll back and Scroll forward buttons are made available.
Clicking these buttons allows you to scroll backward and forward to a time extent that lies within the full time extent of the time slider. This can be thought of as panning across the timeline. For example, if the full time extent is from January 1 to January 10, you can modify the start time and end time of the time slider to be from January 3 to January 7 to focus on just five days that are of interest to you. If the time step interval is set to 1 day on the time slider, clicking the Scroll back button once will allow you to visualize the data from January 2 to January 6. Clicking the Scroll back button again will allow you to visualize data from January 1 to January 5.
The Start time and End time values of the time slider are modified when scrolling forward and back in time. Clicking the Scroll forward and Scroll back buttons modifies the start time and end time of the time slider based on the time step interval set for visualizing your temporal data. For example, if the time step interval you have set on the time slider is 1 day, clicking the Scroll forward or Scroll back button will modify the start time and end time of the time slider by 1 day in either direction based on whether you want to scroll backward or forward in time.
