Differential Equation Graphing 417
Note: If tmax < t0, tstep must be negative. If Fields=SLPFLD, tplot is ignored and is
assumed to be the same as
t0.
tplot First t value plotted. If this is not a tstep increment, plotting
begins at the next tstep increment. In some situations, the
first points evaluated and plotted starting at t0 may not be
interesting visually. By setting tplot greater than t0, you can
start the plot at the interesting area, which speeds up the
graphing time and avoids unnecessary clutter on the Graph
screen.
Variable Description
xmin, xmax,
ymin, ymax
Boundaries of the viewing window.
xscl, yscl Distance between tick marks on the x and y axes.
ncurves Number of solution curves (0 through 10) that will be
drawn automatically if you do not specify an initial
condition. By default, ncurves = 0.
