Tol - Plotting tolerance   

Description:
This attribute specifies the plotting tolerance (or resolution) to be used for the graphical output produced by a Plot. Smaller values will result in smoother and more accurate curves being drawn, but may slow down the plotting process. Conversely, larger values may speed up the plotting process in cases where high resolution is not required.

The Tol value should be given as a fraction of the minimum dimension of the plotting area, and should lie in the range from 1.0E-7 to 1.0. By default, a value of 0.001 is used.

Type:
Floating point.

Class Applicability:
Plot
All Plots have this attribute.
