# HalfLife

The half-life for the paths and blobs on the heatmap. Set this parameter if you want the paths and blobs to decay over time, so that more weight is given to recent activity.

After the specified amount of time, an object's contribution to the heatmap halves. For example, if you set `HalfLife=5 minutes`, the weight is reduced to 1/2 of its original value after 5 minutes, 1/4 of its original value after 10 minutes, 1/8 of its original value after 15 minutes, and so on.

Type: | Time duration The value of this parameter is a time duration. Specify the duration in the following format:
         1days 2hours 3minutes 4seconds 500milliseconds 600microseconds
You can omit any of the individual durations when they are not required:
         4seconds 500milliseconds
You can also shorten the string by abbreviating the units to their first letter (milliseconds abbreviates to ms, microseconds to us):
         4s 500ms
The following are all equivalent:
         1minute 3seconds
         1m 3s
         63s
To specify an infinite duration, use the value `Infinite`.
Default: | Infinite
Required: | No

Example: | `HalfLife=5 minutes`
