Thanks, that worked for me too. I somehow can't get it to work with 'datetime' xaxis though. Would one still use a Range1d object or something else?
Example,
from bokeh.plotting import *
from bokeh.objects import Range1d
from datetime import datetime, timedelta
import numpy as np
output_file('test.html')
dates = [datetime(2013,1,1) + timedelta(x) for x in range(5)]
plot_dates = [np.datetime64(x).astype(long)/1000 for x in dates]
line(plot_dates, range(5), x_axis_type='datetime')
curplot().xrange = Range1d(start=plot_dates[0], end=plot_dates[1]) # here
xaxis().bounds = (plot_dates[0], plot_dates[1])
show()

Mathis,
Ah yes that is a different question, the axes bounds limit the extents to which the axes will draw. You are asking how to restrict the range of the plot. Right now it's a bit clunky, you have to set the x_range attribute of the plot to a Range1D object (these objects will not auto-size to the extents of the data like the DataRange1d will). This code does what you want I believe.
from bokeh.plotting import *
from bokeh.objects import Range1d
output_file('test.html')
hold()
line([1,2,3],[2,3,2])
plot = curplot()
plot.x_range = Range1d(start=1, end=2)
xaxis().bounds = [1, 2]
line([1,2,3],[2,3,2]) # get an error if there is not another renderer
show()
However I discovered a bug, the plot runs into an error if there is not a second renderer after the range is changed (see the commented line above). I have created a GH issue you can follow if you are interested:
