The Time Series red triangle menu contains the following diagnostic options to explore the time series data.
Graph
Shows a submenu of options to control the time series plot appearance.
Time Series Graph
Shows or hides the time series graph.
Show Points
Shows or hides the points in the time series graph.
Connecting Lines
Shows or hides the lines connecting the points in the time series graph.
Mean Line
Shows or hides a horizontal line in the time series graph that depicts the mean of the time series.
Autocorrelation
Shows or hides the Autocorrelation plot in the Time Series Basic Diagnostics Chart. The autocorrelation graph describes the correlation between all pairs of points in the time series for a given separation in time (lag). See Autocorrelation Chart.
Tip: The autocorrelation graph of the sample is often called the sample autocorrelation function.
Partial Autocorrelation
Shows or hides the Partial Autocorrelation plot in the Time Series Basic Diagnostics Chart. The partial autocorrelation graph describes the partial correlation between all the pairs of points in the time series for a given separation in time (lag). See Partial Autocorrelation Chart.
Tip: The Autocorrelation and Partial Autocorrelation graphs can help you determine whether the time series is stationary (meaning it has a fixed mean and standard deviation over time) and what model might be appropriate to fit the time series.
Variogram
Shows or hides the graph of the variogram in the Time Series Basic Diagnostics Chart. See Variogram Chart.
AR Coefficients
Shows or hides the graph of the least squares estimates of the autoregressive (AR) coefficients in the Time Series Basic Diagnostics Chart. See AR Coefficients Chart.
Spectral Density
Shows or hides graphs of the spectral density as a function of period and frequency. The spectral density option also displays the White Noise test report, which gives results from two tests on the data. See Spectral Density Report and Statistical Details for Spectral Density.
