Introduction to Stata 8 - (GRIPS

14.6. Appearance of markers, lines, etc.
Marker symbols
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 ))
The default connect-style is a straight line. Obtain a step-curve like a Kaplan-Meier plot by:
twoway (line cum time , connect(J))
Bars
Bar graphs (twoway bar) and range plots use bar outlines; here the blpattern() and
blwidth() options apply. The colour of the bar fill is defined by the bfcolor() option:
... bar(1, bfcolor(gs9)) bar(2, bfcolor(gs14))
