Series Viewer Transformations Window
Use the Series Viewer Transformations window
to view plots of transformations
of the current series in the Time Series Viewer window.
It provides a larger set of transformations than those
available from the viewer window's tool bar.
It is invoked using Other Transformations under the
Tools pull-down menu of the Time Series Viewer window.
The options that you specify in this window are applied to
the series displayed in the Time Series Viewer window
when you select OK or Apply. Use the Apply
button if you want to make repeated transformations to a series
without having to close and reopen the Series Viewer Transformations
window each time.
