Drawing a Smoothed Graph 

This section tells you how to draw a smoothed graph.  On a smoothed
graph, median values replace data values to produce a smooth curve.  A
smoothed curve makes it easier to see any trend over time.

   1.  Select the Forecasts command under the Draw menu to see the
       following dialog box.


          Forecasts Command Dialog Box 

       Note that Smoothing is the default trending method.  It produces a
       smoothed curve of the data so you can more readily see any trend.

   2.  Make the selections indicated on the dialog box shown above.

          a.  Select Job CPU.

              The metrics are contained in a list box, rather than a
              check box.  You can select more than one metric by holding
              down Shift as you click on each metric you want.  You will
              get a graph for every metric that you choose.  For now,
              just select Job CPU.

          b.  Select Ignore Weekends.

          c.  Use the Shift option to select a standard work day of 8 AM
              to 5 PM.

          d.  Click on  OK to draw the graph.

You should see the following smoothed graph for Job CPU.


            


NOTE  The graphs on your screen should not vary from those depicted in
      this chapter.  Select options carefully to ensure conformity.  If
      you get a different graph than the one depicted, return to the
      dialog boxes to correct your selections.


The blank area on the right-hand side of the graph is typical of a
smoothed graph since the smoothing method does not forecast.  That is, it
projects nothing beyond the actual data.  With the other trending
methods, you will see the area to the right of the data used for the
forecast.

The importance of a smoothed graph is that it can make it easier to spot
a trend in your data.

Close the graph and continue with the next section to produce a forecast.
