'thrs' <value> 'h'|'l'|'o' ['t']
Compiles all nodes which values of the actual dataset are above (h) or below (l) the given value (stored in set '+THRS'). The related elements are collected as well. All unconnected element-clusters from that set together with their related nodes are stored in separate sets (+grp1..+grpn). This sets are displayed in a certain mode were only the edges are visible (see “view”):

thrs 600. h

When the parameter 't' is used the local nodes referencing maximum or minimum values are stored in additional separate sets (+grpN1..+grpNn) and displayed in addition:

thrs 600. h t

This node attached texts can be manipulated with “qtxt
