Turning off Tick Marks in Bokeh

bokeh, python

Solution

This answer is an update for the more recent 0.12.4 version of Bokeh. For additional information, these commands are taken from the Styling Visual Attributes page of the Bokeh documentation.

To turn off the major and minor tick marks set their color to `None`:

p = bokeh.plotting.figure(plot_width=400, plot_height=400)
p.circle([1,2,3,4,5], [2,5,8,2,7], size=10)

p.xaxis.major_tick_line_color = None  # turn off x-axis major ticks
p.xaxis.minor_tick_line_color = None  # turn off x-axis minor ticks

p.yaxis.major_tick_line_color = None  # turn off y-axis major ticks
p.yaxis.minor_tick_line_color = None  # turn off y-axis minor ticks

To turn off the tick labels set the font size to `'0pt'`:

p.xaxis.major_label_text_font_size = '0pt'  # turn off x-axis tick labels
p.yaxis.major_label_text_font_size = '0pt'  # turn off y-axis tick labels

A similar result can be achieved by setting the font color to `None', with the disadvantage that space is still maintained for the tick labels.

p.xaxis.major_label_text_color = None  # turn off x-axis tick labels leaving space
p.yaxis.major_label_text_color = None  # turn off y-axis tick labels leaving space

This code snippet exemplifies removing both the major and minor tick lines and also the tick labels.

p0 = bokeh.plotting.figure(plot_width=200, plot_height=200, 
                           x_axis_label='x', y_axis_label='y',

                           title='notice extra space')
p3.circle([1,2,3,4,5], [2,5,8,2,7], size=10)

p3.yaxis.minor_tick_line_color = None  # turn off y-axis minor ticks
p3.xaxis.major_label_text_color = None  #note that this leaves space between the axis and the axis label  
p3.yaxis.major_label_text_color = None  #note that this leaves space between the axis and the axis label  

grid = bokeh.layouts.gridplot([[p0, p1, p2, p3]])
bokeh.io.show(grid)

Problem

I am working on the Bokeh (0.6.1) tutorial and trying to turn off the tick marks and labels in one of the exercise plots, the scatter plot: ``` from __future__ import division import numpy as np from six.moves import zip from bokeh.plotting import * from bokeh.objects import Range1d output_file("scatter.html") figure() N = 4000 x = np.random.random(size=N) * 100 y = np.random.random(size=N) * 100 radii = np.random.random(size=N) * 1.5 colors = [ "#%02x%02x%02x" % (r, g, 150) for r, g in zip(np.floor(50+2*x), np.floor(30+2*y)) ] circle(x, y, radius=radii, fill_color=colors, fill_alpha=0.6, line_color=None, Title="Colorful Scatter") grid().grid_line_color = None axis().axis_line_color = None # QUESTION PART 1: Is this the right way to turn off tick labels? axis().major_label_text_font_size = '0pt' # QUESTION PART 2: ...and how to turn off tick marks also? show() # open a browser ``` I have managed to turn off the tick labels but no amount of searching the documentation and googling has revealed the incantation needed to turn off the tick marks. Also I am not sure that setting `axis().major_label_text_font_size` to `0pt` is the right way to turn off tick labels or if it is a kludge. Nothing else seemed to work. Am I missing something obvious?
