If X Axis is not t, you must enter at least one initial condition

for each equation in the Y= Editor (whether the equation is
selected or not).
Otherwise, a Diff Eq setup error occurs when you graph.

If no curve is graphed, set an initial condition. If you did enter

A 1st-order equation may look different with FLDOFF than
with SLPFLD. This is because FLDOFF uses the tplot and
tmax Window variables (page 9), which are ignored with
SLPFLD.
Notes
For 1st-order equations, use FLDOFF and Axes = Custom to
plot axes that are not possible with SLPFLD. For example,
you can plot t vs. y1' (where SLPFLD plots t vs. y1). If you
enter mulNotele 1st-order equations, you can plot one
equation or its solution vs. another by specifying them as the
axes.
