xgrid
: adds a grid on a 2D graphic; the
calling parameter is the number of the color.
xtitle
: adds title above the plot and axis
names on a 2D graphic
titlepage
: graphic title page in the middle of
the plot

plotframe
: graphic frame with scaling and grid
We have seen that it is possible to control the tics on the axes, choose the size of the rectangle for the plotand add a grid. This operation can be prepared once and then used for a sequence of different plots. One of the most useful aspect is to get graduations by choosing the number of graduations and getting rounded numbers.
rect=[-%pi,-1,%pi,1]; tics=[2,10,4,10]; plotframe(rect,tics,[%t,%t],... ['Plot with grids and automatic bounds','angle','velocity']);
graduate
: a simple tool for computing pretty
axis graduations before a plot.
