Easily Overlooked Features - Summer 2010

 

This section is designed to highlight one or two features per issue that may be overlooked because they are not made visually obvious with a toolbar button.

Auto Scale Visible Region Command
The Auto Scale command under the Scope menu is a commonly used command that automatically determines the scale ranges in order to best display the waveforms in the plot. However, it will always scale using the data from the entire waveform which may not be appropriate in some situations. The Auto Scale Visible Region command, which is also available under the Scope menu, scales the vertical or Y axis of the waveforms by considering only Y values within the currently visible or displayed X region. This command is useful when you have zoomed in on a small part of a waveform and want to auto scale only the vertical region while maintaining the X axis scale of the original zoom.

An example of the use of the Auto Scale Visible Region command is shown in the figure below. The waveform in each plot group has been set to the same expression: V(Out). When this simulation is originally run, both the top and bottom plots are set to show the entire waveform. The top plot in the figure still maintains its original scale. The bottom plot has been zoomed in on to show the steady state operation of the output after the initial transient has passed. After the zoom in, the Auto Scale Visible Region command was then selected to produce the display shown in the bottom plot.
