drarea
Multiple graphics are produced in Stata by the rule "last drawn
first seen". So the objects that are drawn last are the ones
that are observed. The implication of this principle is that
when overlapping two rarea graphs the overlapping area is hidden
by the second rarea graph. This command drarea overlays two
range area plots by merging the two colours and hence highlighting
the true overlap.
Requires: drarea
to download this program type the following on the Stata command
line (if not already loaded):
ssc install drarea
To run the example: copy the following into a do file and run
sysuse sp500, clear
generate high2 = high+15*uniform()
generate low2 = low+15*uniform()
drarea high low high2 low2 date in 1/20


linkplot
linkplot plots yvarlist versus xvar such that data points are
linked (i.e. connected) within groups defined by distinct values of
linkvar. For example, with paired data it might be desired to
link each pair, or with panel data it might be desired to link
observations within each panel.
Requires: linkplot

binscatter
binscatter generates binned scatterplots, and is optimized for
speed in large datasets.
Binned scatterplots provide a nonparametric way of visualizing the
relationship between two variables. With a large number of observations,
a scatterplot that plots every data point would become too crowded to
interpret visually. binscatter groups the xaxis variable into
equalsized bins, computes the mean of the xaxis and yaxis variables
within each bin, then creates a scatterplot of these data points.
Requires: binscatter
