When more than one graphic-window is existent it is not definite
where commands entered in the text-window are evaluated. A focus to
the window must be set where commands concerning the window should be
evaluated. These are for example commands to plot a window, change the
y-scaling or change its habits, e.g. frame width or tic length. All
commands to configure the graphic window are listed in section
6.9 on page of chapter 6.
By default to set the focus to a window you have to move the mouse into the window. You can set the keyboard-focus to a certain window named ``lifetime'' with the following command, assuming it exists:
tv window setup keyboard-focus title lifetime
and switch back to default behaviour by pressing hotkey L or with the command:
tv window setup keyboard-focus cursor
There are three values for the short, medium and long tic lengths in this order and another one for the distance between the axis-label and the tic. The command to change these values which are given in the unit character size is:
tv window setup frame length 0.2 0.4 0.6 0.75
Another group of commands configures the y-scale of the windows. For example to set the y-scale to logarithmic scale you have to enter the commands:
tv window scaling function-y logarithmic
tv window scaling function-y normalization on
tv window scaling function-y normalization off
These three commands are defined as alias log by default.
You can switch off the graphic display to omit graphical output and thereby accelerate the execution of command files. To do this enter
tv graphic suspend
and to turn it on again enter
tv graphic resume
