Run chart plots observed data on time sequence ( x axis ) . Run charts are analyzed to find anomalies in data that suggest shifts in a process over time or special factors that may be influencing the variability of a process. Typical factors considered include unusually long "runs" of data points above or below the average line, the total number of such runs in the data set, and unusually long series of consecutive increases or decreases.
If you find a pattern in the run chart from your past data, you can always forecast the future. Read this page for more info
