53 | * The Trace class represents a @ref TraceTreeItem which occupies some vertical | |
54 | * space on the canvas and spans across its entire width, essentially showing | |
55 | * a time series of values, events, objects or similar. While easily confused | |
56 | * with @ref Signal, the difference is that Trace may represent anything that | |
57 | * can be drawn, not just numeric values. One example is a @ref DecodeTrace. | |
58 | * | |
59 | * For this reason, Trace is more generic and contains properties and helpers | |
60 | * that benefit any kind of time series items. | |
