first, sorry because I cannot really provide an example, because it happens in a quite complex framework.
Looking for an elegant workaround (an ugly one is implemented, see below) :
Setup: A figure has a glyph (segment), linked to a columndatasource
More glyphs are removed/added on a figure on a change of the source data. With this, no problem.
But the original figure segment glyph often does not respond to this data change.
Workaround now :
Explicitly set the glyph property “y0” to a value and then set it back to the dictionary key
If workaround I need, as it seems for now, is there a way to force a trigger (from python side) on the glyph so it reactualizes to the dictionary values ?
