8.4 Viewing Data
Some definitions are in order:
Each WaveVision4 window can contain only one dataset. If you’d like to examine more than one dataset
simultaneously, you must open more than one WaveVision4 window. You can open additional windows
by choosing New Window from the File menu.
Each WaveVision4 window can contain multiple views of the same dataset. By default, a waveform, FFT,
and histogram view are available for each dataset.
9 Using WaveVision4 Plots
The WaveVision4 software provides several tools to help you interact with plots. A toolbar appears above
each plot, similar to Figure 6.
Seen from left to right, the following tools are available:
Plot Actions menu: This menu contains commands that pertain to this particular plot. You may export
the plot data to a file, print the plot, save it as a graphic, or change the plot’s colors.
Plot Options: This button opens a dialog box with options that pertain to this particular plot. You may turn
off labels, annotations, or other elements in this dialog. The WaveVision4 software maintains default
options for new plots. You may edit the default options by choosing Default Plot Options from the
Settings menu. Each time new data is acquired, the default plot options are used. A change in the
default options results in a permanent change of these defaults.
FFT Options: The toolbar shown in Figure 6 is from an FFT plot, so it contains a button to edit the
options for the current FFT calculations. Depending upon the type of plot, various options may be present
on the toolbar. You may edit the default options by choosing Default FFT Options from the
Settings menu. Each time new data is acquired, the default FFT options are used. A change in the
default options results in a permanent change of these defaults. Please consult the appropriate section
below for more information about these options.
Magnifying glass tool: This tool allows you to zoom in and out to see fine details in the plot. Click and
drag a box from upper-left to lower-right to zoom in on a particular region of your plot. Click and drag a
box from lower-right to upper-left to zoom out. With the magnifying glass tool selected, click the right
mouse button to return to a normal, 100% view.
Arrow Tool: The arrow tool is used to select, move, and edit annotations. To edit an annotation, double
click it with the arrow tool. To delete an annotation, select it with the arrow tool and press the Delete key
on your keyboard. The arrow tool also returns the cursor to reporting information about the point in the
plot that it is on.
A dataset is a set of samples.
A view is a way of looking at a dataset - time domain plot (“normal” waveform), frequency domain plot
(FFT), and histogram are all different ways of looking at a sample dataset.
