twoway (rspike high low tradeday)
(line volmil tradeday, sort yaxis(2)),
yscale(range(700 1400) axis(1)) yscale(range(0 10) axis(2))
This example shows the utility of the
yscale(range())
option. The
yscale(range(700 1400) axis(1))
option sets the range of price to be
from 700 to 1400, shifting that series up
to the upper third of the graph. The
yscale(range(0 10) axis(2))
option
sets the range of volume to occupy the
lower third of the graph.

ylabel(1000 1200 1400, axis(1)) ylabel(0 1 2, axis(2))
Because we manipulated the scale of
the
-axes, the labels were pushed
together. We can add the
ylabel(1000
1200 1400, axis(1))
and
ylabel(0 1
2, axis(2))
options to the previous
example to make the labels for the
y
y
-axes more readable.

Selecting an axis
This section provides more details about how to select different axes and modify them.
By default, any modifications you make to an axis are applied to the first axis, so you need
to take extra action to modify other axes that you may create. For more information about
these options, see [

axis selection options
. For this section, we will use the
vg outc
scheme.
