Detailed Description

The Trace class represents a TraceTreeItem which occupies some vertical space on the canvas and spans across its entire width, essentially showing a time series of values, events, objects or similar. While easily confused with Signal, the difference is that Trace may represent anything that can be drawn, not just numeric values. One example is a DecodeTrace.

For this reason, Trace is more generic and contains properties and helpers that benefit any kind of time series items.
