我是散景新手,我对按钮onclick事件有了兴趣,代码如下:
x = widgetbox(button)
show(x)
fruits = ['Answered', 'Unanswered','Total']
top1=[1,2,3]
def callback():
p = figure(x_range=fruits, plot_height=250, title="sophia bot")
p.vbar(x=fruits, top=top1, width=0.9)
p.xgrid.grid_line_color = None
p.y_range.start = 0
output_file("abc.html")
show(p)
button_one = Button(label="Start", disabled=True, callback=callback)
show(button_one)
但是这并没有执行动作,单独使用下面的代码时,绘制图形,我希望当我按下按钮时图形显示。
fruits = ['Answered', 'Unanswered','Total']
top1=[1,2,3]
p = figure(x_range=fruits, plot_height=250, title="sophia bot")
p.vbar(x=fruits, top=top1, width=0.9)
p.xgrid.grid_line_color = None
p.y_range.start = 0
output_file("abc.html")
show(p)

您必须将回调分配给按钮,如下所示:
from bokeh.models import Button
from bokeh.io import curdoc
bt = Button(label='Click me')
def change_click():
print('I was clicked')
bt.on_click(change_click)
curdoc().add_root(bt)
使用bokeh serve --show example.py
启动此功能。
