TSView Time Series Viewing Tools <br /> Appendix - TSView - 13 <br />Time Series Traces <br /> <br />In general, the term time series traces refers to a group of time series, often shown in overlapp ing fashion. <br />Common uses of time series traces are: <br /> <br />• Separate a full time series into annual traces and plot them on top of each other, shifted so that they <br />all start at the same date/time, <br />• Run a model or analytical tool multiple times, with input being a series of input traces, and generating <br />a series of output traces, in order to produce probabilistic simulations. <br /> <br />The power of using traces is that a large amount of data can be used to visualize and study statistical <br />qualities of the data, as shown in th e following figure. <br /> <br /> Graph_Traces <br />Example Graph for Time Series Traces <br /> <br />The TSView package supports time series traces at various levels. Time series properties include a <br />sequence number that can be used to identify a time series as being in a group of traces. However, for <br />data management and viewing, time series identifiers often do not indicate whether a time series is in a <br />group of traces (the sequence number is managed internally). Full support of time series traces is being <br />phased in. <br /> <br />167
