There's a pile of keywords for BARPLOT that you can add either on
initialisation or subsequently, check the online Help for the BARPLOT
routine.

For example,

b = barplot(data)

(and up pops a barplot with the defaults)

b.xrange = [-1.0, 1.0] ; change the x axis range from -1 to 1
b.yticklen = 0.1 ; double the y axis default tick length
