Tooltips not populating

[ChristopherPAndrews]

I tried the basic tooltip example from the bokeh guide, modified for the notebook and in jupyter lab the tooltip appears, and the labels are present, but not the values -- they are just blank.

from bokeh.plotting import figure, show, ColumnDataSource
from bokeh.io import output_notebook

# set the output to the notebook
output_notebook()

source = ColumnDataSource(data=dict(
    x=[1, 2, 3, 4, 5],
    y=[2, 5, 8, 2, 7],
    desc=['A', 'b', 'C', 'd', 'E'],
))

TOOLTIPS = [
    ("index", "$index"),
    ("(x,y)", "($x, $y)"),
    ("desc", "@desc"),
]

p = figure(plot_width=400, plot_height=400, tooltips=TOOLTIPS,
           title="Mouse over the dots")

p.circle('x', 'y', size=20, source=source)

show(p)

@ChristopherPAndrews I was unable to reproduce your issue using JupyterLab=0.35.2 and Bokeh=1.0.0, so i'd suggest upgrading if you still have a problem. I'm going to close this as "resolved", please re-open if you still have an issue.

@mauermbq your issue appears to be that you have a pretty old version of JupyterLab that's compatible with an old version of jupyterlab_bokeh. I'd suggest upgrading to JupyterLab=0.35.2 and Bokeh=1.0.0, if possible.

unfortunately there is still an isue #60

This is working for me with Bokeh 1.2 and extension 1.0.0next, so closing. I will note the value text is black, so if you are using a "dark" theme or something, that might explain things. I think for now you would have to target CSS to change bokeh built-in text props, but could use a custom tooltip to set whatever CSS/HTML you need.
