On the Graphs tab of the Moving Average dialog box, select the graphs to include in your output.

- Time series plot includes
- Specify whether Minitab displays a time series plot with the fitted data or a plot with the smoothed data. The smoothed data is the level component of the time series. The fitted values are the point estimates of the variable at time (t).
- Residual plots
- Select to have Minitab display all four plots.
- Residuals versus fits
- Display the residuals versus the fitted values. Use the residuals versus fits plot to determine whether the residuals are unbiased and have a constant variance.
- Residuals versus order
- Display the residuals versus the order of the data. The row number for each data point is shown on the x-axis. Use the residuals versus order plot to see how accurate the fitted values are compared to the observed values during the observation period.
- Normal probability plot of residuals
- Display a normal probability plot of the residuals. Use the normal plot of residuals to determine whether the residuals are normally distributed. However, the residuals being normally distributed is not an assumption that has to be met for this analysis.
- Histogram of residuals
- Display the shape and spread of the residuals. Use the histogram of residuals to determine whether the data are skewed or whether outliers exist in the data.

- Residuals versus variables
- Enter one or more variables to plot versus the residuals. Use the residuals versus the variables plot to assess whether a variable that is not in the analysis systematically affects the response.
