use this dialog box and how to write your equations.
There are three main sections in the equation editor plus control
buttons. These sections are described below.
Figure 3-53. The Equation Editor Dialog Box
Anchor The Anchor section has two fields: Start and End Point.
Start (pts) – Defines the first point where the created wave will start.
Note that if you change the start point the left anchor will
automatically adjust itself to the selected start point.
End (pts) – Defines where the created waveform will end. Note that
as you change the end point the right anchor will automatically adjust
itself to the selected end point.
Level Adjuster The Level Adjuster is a convenient tool that helps you adjust the
amplitude and offset without modifying your equation. The Level
Adjuster mode does not interfere with your calculations and displays
the waveform as computed from your equation. The only difference is
that your final calculations are stretched or shrunk or offset on the
vertical scale to fit the new amplitude and offset boundaries.
For example, look at the equation that is shown in Figure 3-23. This
equation will generate a waveform similar to what you can see on
Figure 3-22. If you change the offset setting in the Offset field and
press the Adjust key, your waveform will offset immediately without
changing the equation. The same way, you can also change the
amplitude, or both amplitude and offset. If you check the Manual
option, you’ll have to click on the Adjust button for the Amplitude and
Offset parameters to take effect. The Adjust button name will change
to Restore and back to Adjust if you click on it again. If you check the
Auto option, your waveform will be created automatically with the new
