Cause

This problem occurss if the Date Range of the Usage Trend graph is over 352 days in RSA NetWitness 11.5.x version.

Workaround

Workaround 1

Upgrade NetWitness to 11.6 or later version. This problem does not occur in NetWitness 11.6 or later versions.
 

Workaround 2 

Reduce the date range to 352 days.
For example, the usage trend displays the correct number if the date range is 2021-01-17 to 2022-01-04(352 days) and 2021-01-16 to 2022-01-03(352 days).
But the problem occurs if the date range is 2021-01-16 to 2022-01-04(353 days).
