QL
Easel
is
fully interactive, which means that you
see
the results
of
everything you do
immediately. From the moment you start you can just type
in
a series of numbers and
see
them displayed as a graph, as you type them
In.
You
never
need
to
worry about
building up tables
of
values;
Easel
takes care of that kind
of
thing
for
you,
and keeps
them where they should be
- out
of
Sight.
You
can add text
to
the graph just as simply
as
you enter data and, once
',t
is
there,
you can edit it or
move
it
around
(easily,
of course
l
.)
until
you
are satisfied with the
result.
Easel
is
organised
in
a series
of
levels and exhibits a pyramidal structure. The top
level,
which
IS
immediately available when you
start,
allows
you
to
do the most commonly
needed operations, for example, entering data or
text.
The
full
power
of
Easel
becomes
apparent as you become more familiar
with
it
and dig more deeply into the pyramid.
Despite this
powe( Easel
still
remains simple
to
use
at
all
levels.
You
do not need
to
remember
lots
of
numbers and commands, since
you
are guided through each process
by a carefully designed sequence
of
prompts which explain what
you
can do
at
each
stage.
In
particula(
Easel
has a design
by
example facility which allows you
to
select
or des'lgn anything from a single line or bar
to
a whole graph, simply by choosing from
a
set
of
pictures. With this facility you need
never
be
in
any doubt
as
to
what the
final
appearance
of
your graph
will
be.
If,
af
any
time,
you are not sure what
fa
do,
remember thaf
you
can ask for Help by
pressing
F1
. Also remember that you can cancel any partially completed operation by
pressing ESC.
