INCLAN Graphics: plot scale

Synopsis

plot scale axis f₁... [exact] (list mode)

Description

Performs scaling of the given axis (x or y) on the basis of the vector expressions f₁,... Scaling sets the coordinates of the reference points in the user coordinate system (X₀ and X₁ for the x-axis, Y₀ and Y₁ for the y-axis) such that they include all values of the vector expressions f₁,... If the option exact is present, then the new coordinates of the reference points will correspond exactly to the minimum and maximum of the vector expressions f₁,...; otherwise a small margin will be added in order to avoid that points lie exactly on the boundary.
