Time series. In mathematics, a time series is a series of data points indexed (or listed or graphed) in time order. Most commonly, a time series is a sequence taken at successive equally spaced points in time. Thus it is a sequence of discrete-time data. Examples of time series are heights of ocean tides, counts of sunspots, and the daily ...
Line chart. A line chart or line graph, also known as curve chart, [1] is a type of chart that displays information as a series of data points called 'markers' connected by straight line segments. [2] It is a basic type of chart common in many fields. It is similar to a scatter plot except that the measurement points are ordered (typically by ...
A timeline is a display of a list of events in chronological order. [ 1] It is typically a graphic design showing a long bar labelled with dates paralleling it, and usually contemporaneous events. Timelines can use any suitable scale representing time, suiting the subject and data; many use a linear scale, in which a unit of distance is equal ...
This technique marked the revival of a graphic display after nearly 800 years from the first known time-series use. Over the two centuries since Lambert and Playfair, time-series graphs have been used frequently to show data, or data relationships, for a variety of variables. The meteogram is one application of the time-series graph.
Decomposition of time series. The decomposition of time series is a statistical task that deconstructs a time series into several components, each representing one of the underlying categories of patterns. [1] There are two principal types of decomposition, which are outlined below.
A chart (sometimes known as a graph) is a graphical representation for data visualization, in which "the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart ". [ 1] A chart can represent tabular numeric data, functions or some kinds of quality structure and provides different info.
Fan chart (time series) In time series analysis, a fan chart is a chart that joins a simple line chart for observed past data, by showing ranges for possible values of future data together with a line showing a central estimate or most likely value for the future outcomes. As predictions become increasingly uncertain the further into the future ...
A time series database is a software system that is optimized for storing and serving time series through associated pairs of time (s) and value (s). [1] In some fields, time series may be called profiles, curves, traces or trends. [2] Several early time series databases are associated with industrial applications which could efficiently store ...
