+= Latency Analyses =
+
+Trace Compass offers a feature called Latency analysis. This allows an analysis to return intervals and these intervals will be displayed in four different views. An example analysis is provided with kernel system call latencies being provided. The available views are:
+
+* System Call Latencies
+A '''table''' of the raw latencies. This view is useful to inspect individual latencies.
+

+
+
+* System Call Latency vs Time
+A time aligned '''scatter chart''' of the latencies with respect to the current window range. This view is useful to see the overall form of the latencies as they arrive.
+

+
+
+* System Call Latency Statistics
+A view of the total '''statistics''' of the latencies. These show the ''minimum'', ''maximum'', ''average'' and ''standard deviation'' of the latencies when applicable. This tool is useful for finding the outliers on a per-category basis.

+
+
+* System Call Density
+A '''density''' view, analyzing the current time range. This is useful to find global outliers.

= Limitations =
* When parsing text traces, the timestamps are assumed to be in the local time zone. This means that when combining it to CTF binary traces, there could be offsets by a few hours depending on where the traces were taken and where they were read.
