散景图的 X 和 Y 轴标签

Question

Does anyone know how to add x and y axis title/labels for a Bokeh figure? Eg X-axis: time, Y-axis: stock price.

Thanks a lot!

Answer 1

As of Bokeh 0.11.1, the user's guide section on axes now shows how to edit properties of existing axes. The way to do it is the same as before:

p = figure(width=300, height=300, x_axis_label='Initial xlabel')
p.xaxis.axis_label = 'New xlabel'

Answer 2

Check out this example: elements.py

You can also now give general plot related options ( plot_width , title , etc.) to a call to figure(...) instead of the renderer function ( circle , in that example)

Answer 3

This is how you can change the axis label using CustomJS :

p = figure(x_axis_label="Initial y-axis label",
           y_axis_label="Initial x-axis label")

# ...

# p.xaxis and p.yaxis are lists. To operate on actual the axes,
# we need to extract them from the lists first.
callback = CustomJS(args=dict(xaxis=p.xaxis[0],
                              yaxis=p.yaxis[0]), code="""
    xaxis.axis_label = "Updated x-axis label";
    yaxis.axis_label = "Updated y-axis label";
""")

Answer 4

from bokeh.plotting import figure, output_file, show
from bokeh.models.annotations import Title
p = figure(plot_width=1300, plot_height=400,x_axis_type="datetime")
p.xaxis.axis_label = 'Time'
p.yaxis.axis_label = 'Stock Price'
p.line(time,stock_price)
t = Title()
t.text = 'Stock Price during year 2018'
p.title = t
show(p)
