# How to put a “coil” inside an ncline (between nodes)?, in PStricks

How to put a "coil" in an \ncline between nodes?

similar to:

I have viewed \pscoil and options as coilarm=0.5,..

but.... in \ncline or similars?, how?

I have this code, for example

\documentclass[12pt,a4paper,x11names]{article}

\usepackage[utf8]{inputenc}

It is possible to use the same node for a line. The different coordinates can be done by setting nodesep and offset. Everything refers to the center of the node Inicio which is the center of the frame:

[ ... ]
\ncline{Conjunto}{EM}
\pccoil[arm=10mm,linewidth=2pt,coilwidth=5mm]{<-}%
([nodesep=1cm,offset=-2cm]Inicio)([nodesep=4cm,offset=6cm]Inicio)
[ ... ]


• It´s all right :-) but What shock me is that nodesep don´t works as with nodes. if you use nodesep=1cm (one is separted, but the other is overwriting the other node.) The solution is easy,.. one nodesep>0 and other <0, but... it seems to be no natural, as you can see dropbox.com/s/uasls5d2kyhdaoq/stack04h.tex – Mika Ike Jun 3 '14 at 9:23

With use of Manuels package pst-ressort (you can get it here: tex-File, the style-File and the documentation)
