4.3.0 Time Animation Widget
Each IDV display area or View Manager (a view window and controls) has a set of time animation controls above the view window.
The Time Animation Widget controls looping of displays through time. A series of small green boxes is displayed representing each frame of the animation. The box corresponding to the current time is colored blue. Click on a box to select a different time. Right click on a box to disable that frame in the animation. Disabled boxes will be colored red. The time of the data is displayed in the labeled pull-down list and in the entries of the pull down list on the left. The toolbar of button icons, on the right, control time animation. Reading from left to right, the icons on the Time Animation Widget do the following:
4.3.1 Time Animation Properties Dialog
Click on the i in the animation controls to see the Time Animation Properties Dialog box. This dialog has two tabs.
By pressing Apply or OK you will set the properties in the Animation Widget. If you have the Save As Default button checked then the properties will be saved off and used every time a new Animation Widget is created. For example, you may find that you are always setting the dwell rate to a particular value. You can save that state off as the default state for all Animation Widgets that are subsequently created, both in the current run of the IDV and in future runs.
4.3.2 Settings Tab
The first tab allows you to change the values that control looping.

The Dwell controls how fast the animation occurs. Click on the slider icon: to change the values. Values are seconds/frame.

Select the looping style with the Direction menu. Share the time animation in a display with the animation in other displays with the Share Times button. See here for more information.

Check Boxes Visible to show the boxes in the Time Animation Widget. The time boxes allow you to configure which frames will be disabled in the Time Animation Widget. This behaves the same as the boxes in the main widget.

You can also set the behavior for when the set of times available changes with the Reset->To menu. The options are the Start Time, End Time, or No Change.

4.3.3 Define Animation Times Tab
The second tab allows you to define a custom animation time set.
By default, the times used in the animation time set are all of the times from the data that is being displayed. However, you can define your own time set by selecting the Define your own list of times button.

You define how to determine the start time, end time and a time interval. The Interval is used to create the set of time steps (inclusive) between the start and end times. The start time and end time modes are determined one of four ways:

Once you select the start and end time modes you can define an offset which is added (or subtracted) to the base time. To change the offset select the button. When you do this the Offset Dialog will be shown:
This allows you to define a time offset by entering days, hours and minutes. Note, you can also specify a sign, "-" or "+".

If you check the Set as Time Driver checkbox, the times that you set are used as the Time Driver times. You can then load in data to match to these times. See the Field Selector section for more information.

By pressing the Apply button, you can apply the changes that you have made. This is also a good way to see if there are any errors. For example, the end time cannot be less than the start time.
