graph bar wage hours ttl exp tenure, over(collgrad)
intensity(*.5)
The
intensity
option is used to
control the intensity of the color within
the bars. Here, we request that the
color be 50% as intense as it normally
would be.

graph bar wage hours ttl exp tenure, over(collgrad)
intensity(*1.4)
In this example, we use the
intensity()
option to make the colors
within the bars 1.4 times more intense
than they would normally be. Note
that Stata also has an option called
lintensity()
that works the same way
but controls the intensity of the line
surrounding the bar. (This option is
not illustrated.)

So far, all these options that we have examined determine the overall behavior and look
over all of the bars as a group. Using the
bar()
option, you can control the look of the
bars for each
y
-variable, as illustrated below. These graphs use the
vg s2c
scheme.
