The following describes the most significant changes which
occurred in the AST library between versions V1.8-4 and V1.8-5:
- The PlotPlot class defines new graphical elements Axis1, Axis2,
Grid1, Grid2, NumLabs1, NumLabs2, TextLab1, TextLab2, Ticks1 and Ticks2.
These allow graphical attributes (colour, width, etc) to be set for each
axis individually. Previously, graphical attributes could only be set for
both axes together, using graphical elements Axes, GridGrid, NumLabs,
TextLabs and Ticks.
