FuncTickFormatter

I need to assign custom labels stored in a dictionary to
graph axis. The following code used to work before the 0.12.9 release.

Xlabel = {1:‘one’,2:‘two’,3:‘three’}

p.xaxis.formatter =
FuncTickFormatter(code="""

var labels
= %s

return
labels[tick]

“”"
% Xlabel)

Could someone tell me how to adjust the code?

Thank you!

Can you provide a minimal example that doesn’t work for you?

This code:

from bokeh.io import show, output_file
from bokeh.models import FuncTickFormatter
from bokeh.plotting import figure

f = figure()
Xlabel = {1: 'one', 2: 'two', 3: 'three'}
f.xaxis.formatter = FuncTickFormatter(code="""
            var labels = %s;
            return labels[tick] || tick;
            """ % Xlabel)
f.circle(x=[1, 2, 3], y=[1, 2, 3])

output_file('test.html')
show(f)

works just fine on Bokeh 0.12.9 - I just added “|| tick” to avoid “undefined”.

Regards,

Eugene

Eugene, thanks a lot for your reply. Your example works fine on my computer. I have realized that my issue is more specific that I thought, maybe related to bkcharts? Here is the example:

from bkcharts import Bar

from bokeh.plotting import figure

from bokeh.io import show, output_file

from bokeh.models import FuncTickFormatter

import pandas as pd

P = {‘col1’:[1,2,3,4,5,6], ‘col2’:[10,5,34,7,22,2]}

Labels ={0:‘zero’,1:‘one’,2:‘two’,3:‘three’,4:‘four’,5:‘five’}

df = pd.DataFrame(P)

p = figure()

p = Bar(df,legend=None,plot_height = 200,plot_width = 300,values = ‘col2’)

p.xaxis.formatter = FuncTickFormatter(code=“”"

var labels = %s;

return labels[tick] || tick;

“”" % Labels)

output_file(‘test.html’)

show(p)

bkcharts is deprecated and unmaintained. Could you try changing you examples so it uses Bokeh?
