# Mathematical Symbols and Greek Letters

The following example shows Greek letters and mathematical symbols in the x and y axis titles.

; Define the data.

t = 0.1*FINDGEN(200)

y = SMOOTH(RANDOMU(seed,200), 5)

; Draw the plot

p = PLOT(t,y,'b', $

XTITLE='Gap Distance ($\AA$)', $

YTITLE='Volts ($\mu$V)', $

FONT_SIZE = 20, $

DIMENSION=[640,512], $

SYMBOL = 'circle', $

SYM_FILLED = 1, $

SYM_FILL_COLOR = 'gold')

For complete information on using the syntax, see TEXT.
