43 /** \class TParallelCoordEditor
44 
45 This is the TParallelCoord editor. It brings tools to explore datas
46 Using parallel coordinates. The main tools are:
47 
48  - Dots spacing : Set the dots spacing with whichone the lines
49  must be drawn. This tool is useful to reduce the image
50  cluttering.
51  - The Selections section : Set the current edited selection and
52  allows to apply it to the tree through a generated entry list.
53  - The Entries section : Set how many events must be drawn.
54  A weight cut can be defioned here (see TParallelCoord for a
55  a description of the weight cut).
56  - The Variables tab : To define the global settings to display
57  the axes. It is also possible to add a variable from its
58  expression or delete a selected one (also possible using right
59  click on the pad.
