Method setSelectionTolerance

qcustomplot/qcustomplot.cpp:13161–13164

! Sets the tolerance that is used to decide whether a click selects an object (e.g. a plottable) or not. If the user clicks in the vicinity of the line of e.g. a QCPGraph, it's only regarded as a potential selection when the minimum distance between the click position and the graph line is smaller than \a pixels. Objects that are defined by an area (e.g. QCPBars) only react to clicks
