python散景图如何格式化轴显示

Question

y轴刻度似乎是格式化数字,如500000000到5.000e + 8.有没有办法控制显示器,使其显示为500000000？

使用python 2.7,散景0.5.2

我在散景教程页面尝试时间序列示例

该教程将'Adj Close'与'Date'进行对比,但我正在用'Volume'对'Date'进行绘图

Answer 1

您还可以使用下面玩具图中使用的NumeralTickFormatter.此处列出了代替'00'的其他可能值.

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)

Answer 2

您必须为p.left[0].formatter.use_scientific = False代码添加选项.在时间序列教程中,它是:

p1 = figure(title="Stocks")
p1.line(
    AAPL['Date'],
    AAPL['Adj Close'],
    color='#A6CEE3',
    legend='AAPL',
)

p1.left[0].formatter.use_scientific = False # <---- This forces showing 500000000 instead of 5.000e+8 as you want

show(VBox(p1, p2))
