Intro to the VIEWS menu
The VIEWS key pops up a menu from which you can choose various
options. Part of the
VIEWS menu for the Function aplet is shown right.
See page
85 for more detailed information. A summary only is given
below.
Essentially the
VIEWS menu is provided for two purposes…
Firstly, within the standard aplets (Function, Sequence, Solve etc.) it provides a list of special views available
to enhance the
PLOT view.
For example the standard
PLOT screen provides a standard graph
covering the whole screen, but the
VIEWS menu lets you use a split
screen such as shown right. Information on the
VIEWS menu is given in
the chapter dealing with the Function aplet.
In its second role, the
VIEWS key also has a critical purpose when using aplets which have been downloaded
from the Internet. When a programmed aplet is created for the hp 39gs or hp 40gs, a menu is provided by
the programmer to let you control and use it. During the programming this menu is tied to the
VIEWS key,
replacing the menu normally found on the key.
For example, the snapshot shown right is of a
VIEWS menu taken from
an aplet designed to analyze and graph Time Series data.
The next important key is the
HOME key. It allows you to change into
the
HOME view from wherever you are. Above it is the MODES key,
accessed by pressing
SHIFT first. More detailed information on these
two views follows later.
