Draws a line through a section (or path) out of a tree intree. The section must be a directed path away from the root as obtained by “dissect_tree” for example (or “ipar_tree”). Plot is offset by XYZ 3-tupel DD and coloured with RGB 3-tupel color. Providing parental paths matrix ipar (see “ipar_tree”) speeds up the plotting significantly. HP is the handle to the graphical object. indy outputs the nodes on the path.


>> [HP indy] = plotsect_tree (sample2_tree, [1 13], [1 0 0]);
selected section is - start node: 1; end node: 13
RGB values correspond to red

>> indy

[13, 12, 11, 10, 3, 2, 1]

>> set (HP, 'marker', '.');
