twoway
bar
close tradeday
Here is an example of a
twoway bar
plot. For each
x
-value, a bar is shown
corresponding to the height of the
y
-variable. Note that this shows a
continuous
-variable as compared with
the
graph bar
command, which would
be useful when we have a categorical
x
x
-variable. See
Twoway : Bar
(62) for
more details about bar plots.

rarea
high low tradeday, sort
This example illustrates the use of
rarea
(range area) to graph the high
and low prices with the area filled. If
we used
rline
(range line), the area
would not be filled. See
Twoway : Range
(64) for more details.

rconnected
high low tradeday, sort
The
rconnected
(range connected)
command makes a graph similar to the
previous one, except that a marker is
shown at each value of the
-variable
and the area in between is not filled. If
we instead used
rscatter
(range
scatter), the points would not be
connected. See
Twoway : Range
(64) for
more details.
