ray glyphs not working when figure's y_axis_type='log'

ALL software version info (bokeh, python, notebook, OS, browser, any other relevant packages)

Using bokeh 0.13.0 on jupyter notebook, Mac, Safari

Description of expected behavior and the observed behavior

When a ray is placed on a figure with y_axis_type=‘log’, the ray does not appear on the figure when plotted. However, when y_axis_type is ‘linear’, the ray works fine.

Complete, minimal, self-contained example code that reproduces the issue

p = figure(y_axis_type='log')
p.ray(x=[0], y=[0], length=0, angle=np.pi/2, line_width=1)
p.ray(x=[0], y=[0], length=0, angle=np.pi*3/2, line_width=1)
show(p)

I see. The reason I used the ray glyph instead of span was so that I could add it to a plot legend and click to hide. Is there any way to do that with a span annotation?

[bryevdv]

No, but in that case I would suggest a single line is better anyway:

from bokeh.io import output_file, show
from bokeh.models import Legend, LegendItem
from bokeh.plotting import figure

from bokeh.models import Span
p = figure(y_axis_type='log', x_range=(-5, 5), y_range=(10e-10, 10e10))
span = Span(location=0, dimension='height', line_color="red")

r = p.line(x=[1,1], y=[10e-20, 10e20])
p.add_layout(span)
p.add_layout(Legend(items=[LegendItem(label="span", renderers=[r])]))

show(p)

As this has now entered “general support question” territory I have to request that further discussion move to the mailing list.
