MULTIPLE CHANNELS...
Allows you to plot any combination of the channels
in the file. There are two 'modes' of channel display: Full Screen
and Plot Area.
- In Full Screen mode, the data plots fill up the entire available
screen area. You can change between the 'entire file' and 'active
screen' modes and shift between screens using the normal channel change
buttons or the left and right arrow keys. Also, a small floating window at the right of the plot area indicates the active channel and lets you change active channels through button clicks. The other channel-change options continue to work.You can also send an image
of the file to a printer or load new files, but most analyses and edit
menu functions are not usable. You need to click the close box to
get back to the regular analysis screen.
- In Plot Area mode, the channels are plotted within the normal
plot area and you can use all the normal edit and analysis menu functions.
Clicking the 'Use Standard Multichan Settings' button tells the program to plot all channels in the file at normal (equal) plot heights, with no further questions.  
If you click the 'Next..'. button, a channel selection window allows you to pick any combination
of the available channels. If you click the 'non-standard plot
height' button, a window will open to allow customization of the height
of each channel:
The window for customized plotting contains a diagram
of the printed page. You select the relative height of each channel
in sequence by moving the cursor on the diagram to the desired height, and
then clicking the mouse ONCE. The channels will be redrawn
one by one as their heights are selected. Note that there is a fixed
amount of room on the screen, so that enlarging one channel requires shrinking
one or more of the others. Consequently, the computer reserves an
amount of space necessary for drawing the remaining channels at the minimum
possible height (and will not let you exceed that limit). You must
select plot heights for all the channels. When done, you can accept
the results, re-do the plot height selection, or revert to the normal setting
(all channels drawn with equal heights).
When done, click the 'Plot heights OK' button, and the selected
channels will be drawn.

Example of a multi-channel display with 5 channels out of 6 shown.
These channels are plotted in normal scaling mode.
- NOTE: if the file contains only one channel, the menu reads FULL
SCREEN instead of MULTIPLE CHANNELS.
