Bokeh 0.12.2
is it possible to add python callbacks to quad?
stack = figure(width=480, height=self.height_scatter,y_axis_location=None,x_axis_label=‘Miles’, title=‘Longest Miles’)
q = stack.quad(top=‘top’, bottom=‘bottom’, left=0, right=‘right’, color=‘orange’, alpha=.8, source = self.quad_source)
``
When selecting a quad I would like to(for now) print information about the source of each quad using pythons print().
