Notes

(a)

When RUNDEF  is specified as X or Y, it is considered that the points dividing the range defined by UUSIDV into N-1 equal sections have been specified. If the defined range is not specified, then the whole window is considered to be the defined range.

(b)

When RUNDEF  is specified as X1, Y1 or X2, Y2, it is considered that the value of the internal variable 'UREF' has been specified. The initial value of 'UREF' is 0.

(c)

The attributes of the error bars drawn by UVERB, UHERB is specified by UUSEBT, UUSEBI, USSEBS.
