Getting the Series into the Window

 

The results of calculations or raw data reside in windows within the worksheet. To display multiple series in one window, use the OVERLAY or OVERLAY function. These functions are available through the View pulldown menu. The OVERPLOT function ties each series to the same set of scales or axes, while the OVERLAY function provides a separate set of scales for each series in the window. For Example:

 

W1: gsin(100, 0.01);setvunits("Volts")

W2: gcos(100, 0.01);setvunits("Amps")

 

To create a window with both series displayed, and only one set of scales, move to W3, and type: W1, then select Overplot from the View pulldown menu, and enter in the series to overplot (W2) and choose a color. Or, type at the command line:

 

w1; overplot(w2, red)

 

To create a window with both series displayed, where each one has its own set of scales, move to W3, and type: W1, then select Overlay from the View pulldown menu, and enter in the series to overlay (W2) and choose a color. Or, type at the command line:

 

w1; overlay(w2, red)

 

Notice how each series has its own scales displayed in the window. Click on a set of scales, and it will change to the color of the series with which it is associated. By clicking on the scales, you set the FOCUS on a particular series. Any commands you issue to change the attributes of the curve apply to that series which is in focus.

 

Add a third series to the overlay window, an XY Plot of the sine versus the cosine, via the View pulldown menu or by typing the command:

 

 w1; overlay(w2, red); overlay(xy(w1,w2), green)

 

Notice how the scales on the top and right (for the red and green curves) are "staggered" away from the plotting area.
