title: bokeh, two y axis, disable one axis for zoom/ panning
body: <p>similar to the matplotlib <code>ax.set_navigate(False)</code> command possible?</p>
  
  <p>Here is a minimal example using ipython notebook.</p>
  
  <pre><code>from bokeh.plotting import figure
  from bokeh.models import LinearAxis, Range1d
  from bokeh.io import output_notebook, show
  output_notebook()
  
  s1=figure(width=250, plot_height=250, title=None, tools="pan, wheel_zoom")
  s1.line([1, 2, 3], [300, 300, 400], color="navy", alpha=0.5)
  s1.extra_y_ranges = {"foo": Range1d(start=1, end=9)}
  s1.add_layout(LinearAxis(y_range_name="foo"), 'right')
  s1.line([1, 2, 3], [4, 4, 1], color="firebrick", alpha=0.5, y_range_name="foo")
  show(s1)
  </code></pre>
  
  <p>Is is possible to hold the second y axis in place, while zooming and panning in the other y axis?<br>
  Using PanTool dimensions did not help me with this problem.</p>
  
  <p>Edit: Screenshot inserted:</p>
  
  <p><img src="https://i.stack.imgur.com/bDuhA.png" alt="Screenshot actual output"><br>
  Blue line is drawn on the first axis, red on the second</p>
  
  <p>If I zoom in, pan around the x axis, I want the red line to keep in place.</p>
