python bokeh bokeh如何格式化轴显示 [英] python bokeh plot how to format axis display

问题描述

y轴刻度似乎是格式化数字，如500000000至5.000e + 8.有没有一种方法可以控制显示，使其显示为500000000?

the y axis ticks seem to be formatting numbers like 500000000 to 5.000e+8. Is there a way to control the display so that it displays as 500000000?

使用python 2.7，散景0.5.2

using python 2.7, bokeh 0.5.2

我正在bokeh教程页面上尝试时间序列示例

i m trying out the timeseries example at bokeh tutorials page

本教程将"Adj Close"与"Date"相对应，但我将"Volume"与"Date"相对应

The tutorial plots 'Adj Close' against 'Date' but i'm plotting with 'Volume' against 'Date'

推荐答案

您还可以使用下面的玩具图中使用的NumeralTickFormatter.在此处.

You can also use NumeralTickFormatter as used in the toy plot below. The other possible values in place of '00' are listed here.

import pandas as pd
import numpy as np
from bokeh.plotting import figure, output_file, show
from bokeh.models import NumeralTickFormatter

df = pd.DataFrame(np.random.randint(0, 90000000000, (10,1)), columns=['my_int'])
p = figure(plot_width=700, plot_height=280, y_range=[0,100000000000])
output_file("toy_plot_with_commas")

for index, record in df.iterrows():
    p.rect([index], [record['my_int']/2], 0.8, [record['my_int']], fill_color="red", line_color="black")

p.yaxis.formatter=NumeralTickFormatter(format="00")
show(p)
