title: Bokeh hover tooltip not displaying all data - Ipython notebook
body: <p>I am experimenting with Bokeh and mixing pieces of code. I created the graph below from a Pandas DataFrame, which displays the graph correctly with all the tool elements I want. However, the tooltip is partially displaying the data.</p>
  
  <p>Here is the graph:</p>
  
  <p><img src="https://i.stack.imgur.com/BYKnc.png" alt="bokeh chart with tooltip"></p>
  
  <p>Here is my code:</p>
  
  <pre><code>from bokeh.plotting import figure, show
  from bokeh.io import output_notebook
  from bokeh.models import HoverTool
  from collections import OrderedDict
  
  x  = yearly_DF.index
  y0 = yearly_DF.weight.values
  y1 = yearly_DF.muscle_weight.values
  y2 = yearly_DF.bodyfat_p.values
  
  #output_notebook()
  
  p = figure(plot_width=1000, plot_height=600,
             tools="pan,box_zoom,reset,resize,save,crosshair,hover", 
             title="Annual Weight Change",
             x_axis_label='Year', 
             y_axis_label='Weight',
             toolbar_location="left"
            )
  
  hover = p.select(dict(type=HoverTool))
  hover.tooltips = OrderedDict([('Year', '@x'),('Total Weight', '@y0'), ('Muscle Mass', '$y1'), ('BodyFat','$y2')])
  
  output_notebook()
  
  p.line(x, y0, legend="Weight")
  p.line(x, y1, legend="Muscle Mass", line_color="red")
  
  show(p)  
  </code></pre>
  
  <p>I have tested with Firefox 39.0, Chrome 43.0.2357.130 (64-bit) and Safari Version 8.0.7. I have cleared the cache and I get the same error in all browsers. Also I did pip install bokeh --upgrade to make sure I have the latest version running.</p>
