Samples
This box is informative only and shows the number of observations in the time series.

Change Time Series
Allows you to choose another time series for modeling.

Distribution
Allows you to visualize the distribution of the time series. This plot shows a maximum of 250 points at a time and, therefore, for time series with more than 250 records you must move the scroll bar on the right of the table and APS will redraw the plot starting at the first visible row. Then, by placing the cursor over the plot, APS shows you the range used to draw the plot.
