twoway scatter propval100 rent700 popden
Here, we show two
-variables,
propval100
and
rent700
, graphed
against population density,
popden
.
Note that Stata has created a legend,
helping us see which symbols
correspond to which variables. We can
use the
legend()
option to customize
it.

twoway scatter propval100 rent700 popden,
legend(cols(1))
Using the
legend(cols(1))
option, we
make the legend display in a single
column. Note that we did not use a
comma because, with the
legend()
option, there is no natural default
argument. If we had included a comma
within the
legend()
option, Stata
would have reported this as an error.

twoway scatter propval100 rent700 popden,

)
This example adds another option
within the
legend()
option,
label()
,
which changes the label for the first
variable.
