col_num integer, 1, ..., count of columns of di
data_num integer, 1, ..., count of data sets plotted in this plot
Output:
data a complex object that includes following components:
a matrix of the points
pcolor a (nx3) matrix of color
pstyle (nx1), style
psize (nx1), size.

Example:

x=(1:10)
x=x~(sin(x/5))
setmaskp(x, 4, 5, 8)
d=createdisplay(1, 1)
show(d, 1, 1, x)
x=1
x=getdata(d, 1, 1, 1)
x
