Herbert, <br>in your example arrows=-> makes arrows, i.e., <br>\psplotDiffEqn[ArrowInside=->]{0}{8}{4}{\Func}<br>does not give any arrows (at least in on my computer)<br>I generate many points solving given equation. Having a curve along them I like to put few arrows on it. In a meantime I have checked that ArrowInside works for psline but \pscurve[ArrowInside=->](0,0)(4,2)(3,1) does not give arrows on curve. Does it mean that
<br>ArrowInside shoud be used only with \psline?<br>-Andrzej<br> <div><span class="gmail_quote">On 3/14/07, <b class="gmail_sendername">Herbert Voss</b> <<a href="mailto:LaTeX@zedat.fu-berlin.de">LaTeX@zedat.fu-berlin.de
