Sets the input focus for Windows with overlayed series by specifying which series are to respond to the scrolling and scaling commands.
FOCUS(win, sernum)
win |
- |
Optional. A window, defaults to the current Window. |
sernum |
- |
Optional. An integer designating the series. Defaults to the first series in the current Window. Series are counted starting at 1. |
W1: gnorm(1000,1)
W2: integ(w1)
W3: w1*w2;overlay(W1, lred);overlay(w2, lgreen)
focus(w3, 2)
In this example, W3 has 2 overlayed series, the second one responds to the scrolling and scaling commands.
The SYNC function can be used to "share" scrolling and scaling attributes. The SCALES function can be used to explicitly set types of scales used for the series.
