Introduction to Stata 8

A text block is placed in the plot area by giving its y and x coordinates; place(c) (the
default) means that the coordinates apply to the center of the text block; place(se) that
they apply to the block's southeast corner. See example in Figure 1 and the twoway line
plot, section 14.7:
... , text(90 69 "1999-2000")
14.6. Appearance of markers, lines, etc.
Options and their arguments for defining the appearance of lines, bars and markers:

Markers are defined by symbol: msymbol(), outline colour: mlcolor(), fill colour
mfcolor() and size msize(). To define a hollow circle:
twoway (scatter mpg weight , msymbol(Oh))
A hollow circle (Oh) is transparent. Obtain a circle with a non-transparent white fill by:
twoway (scatter mpg weight , msymbol(O) mfcolor(white))
Connecting lines
The twoway line and twoway connected examples, section 14.7, use connecting
lines; here the clpattern() and clwidth() options apply:
twoway (line m1840-k1999 age , clpattern( - l - l – l ))
