Method drawBracket

src/qt/qcustomplot.cpp:16491–16524

! Draws the bracket shape with \a painter. The parameter \a direction is either -1 or 1 and indicates whether the bracket shall point to the left or the right (i.e. is a closing or opening bracket, respectively). The passed \a painter already contains all transformations that are necessary to position and rotate the bracket appropriately. Painting operations can be performed as if dra
