bqplot tooltip not showing

[davidbrochart]

In the example notebook, if you change the Line chart section with the following:

fig2 = plt.figure( title='Line Chart')
np.random.seed(0)
p = plt.scatter(x, y)

fig2.layout.width = 'auto'
fig2.layout.height = 'auto'
fig2.layout.min_height = '300px' # so it shows nicely in the notebook
fig2

p.interactions = {'click': 'select'}
p.selected_style = {'opacity': 1.0, 'fill': 'DarkOrange', 'stroke': 'Red'}
p.unselected_style = {'opacity': 0.5}
p.tooltip = bqplot.Tooltip(fields=['x', 'y'], formats=['', '.2f'])

# brushintsel = bqplot.interacts.BrushIntervalSelector(scale=p.scales['x'])

# def update_range(*args):
#     if brushintsel.selected is not None and brushintsel.selected.shape == (2,):
#         mask = (x > brushintsel.selected[0]) & (x < brushintsel.selected[1])
#         hist.sample = y[mask]
    
# brushintsel.observe(update_range, 'selected')
# fig2.interaction = brushintsel

There should be a tooltip on hover and a select on click. Both work in the notebook, but the tooltip on hover doesn't show in voila (the select on click works fine).

Thanks for reporting this issue.

If I run your example in a notebook, I don't see a tooltip on hover or select on click. Could you check your example?

You should see something like this:

It looks different on my system:

$ conda list |grep -E 'bqplot|ipywidgets|notebook'
bqplot 0.11.6 py_0 conda-forge
ipywidgets 7.5.1 py_0 conda-forge
notebook 6.0.0 py37_0 conda-forge

It's plt.scatter, not plt.plot.

D'oh! I can reproduce the issue now. Thanks.
