Types of time series charts Time series charts include: Resource Time Series (RTS). Generally, the horizontal axis of the chart or graph is used to plot increments of time and the vertical axis pinpoints values of the variable that is being measured. Serial dependence occurs when data points close together in time tend to be related. Tips. Look for "Area Line Chart" in the list of charts. The list of most commonly used graph types are as follows: Statistical Graphs (bar graph, pie graph, line graph, etc.) Also called a pie charttime series: type of line graph in which the horizontal axis shows time and the vertical axis displays another variable. Histograms and Density Plots. Besides, it has a horizontal axis that depicts a continuous progression, i.e., time. Additive Decomposition Additive decomposition argues that time series data is a function of the sum of its components. The values are aggregated using time intervals based on the time range in the data being plotted. This section displays many timeseries examples made with Python, Matplotlib and other libraries. Sometimes it's useful to show more than one set of data on the same axes. Time Series Graphs. Line Chart This chart visualizes data as a series of markers or points connected by a curve or a line.
