/* Begin_Html
<center><h2>The TParallelCoord editor class</h2></center>
This is the TParallelCoord editor. It brings tools to explore datas
Using parallel coordinates. The main tools are:
</ul>
<li> Dots spacing : Set the dots spacing with whichone the lines
  must be drawn. This tool is useful to reduce the image
  cluttering.
<li> The Selections section : Set the current edited selection and
  allows to apply it to the tree through a generated entry list.
<li> The Entries section : Set how many events must be drawn.
  A weight cut can be defioned here (see TParallelCoord for a
  a description of the weight cut).
<li> The Variables tab : To define the global settings to display
  the axes. It is also possible to add a variable from its
  expression or delete a selected one (also possible using right
  click on the pad.
</ul>
