# 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 a value using one or more of the following units:
         days          d
         hours         h
         minutes       m
         seconds       s
         milliseconds  ms
         microseconds  us
For example, all of the following are equivalent:
         1minute 3seconds
         1m 3s
         63s
To specify an infinite duration, use the value `Infinite`.
Default: | Infinite
