我是散景的初學者,我想知道是否有可能在HTML文件中保存curdoc()
?我們可以採取如下我的小測試的例子:用散景保存一個curdoc
import numpy as np from bokeh.palettes
import RdYlGn11 as palette from bokeh.plotting
import figure from bokeh.layouts
import row, widgetbox from bokeh.models
import ColumnDataSource from bokeh.models.widgets
import Slider, TextInput, Select from bokeh.io
import curdoc, output_file, save, set_curdoc
x = np.array([-10., -8., -7., -2., 0., 1., 2., 5., 7., 9.])
y = np.array([-15., -12., -9., -5., 1., 4., 6., 7., 9., 12.])
def f(x, y, a, b):
return a * x + b * y
z = f(x, y, -2, 3.2)
colors = np.array(palette)
task_color = np.arange(-10, 10, 10)
source = ColumnDataSource(data = dict(X = x, Y = y, Z = z, color = colors[task_color.searchsorted(z)]))
plot = figure(plot_height = 800, plot_width = 800)
plot.circle("X", "Y", size = 10, line_color = "color", fill_color = "color", source = source)
plot.text("X", "Y", text = "Z", source = source)
A = Slider(title = "First coefficient", value = -2., start = -10, end = 10, step = 1.)
B = Slider(title = "Second coefficient", value = 3.2, start = 0., end = 5., step = 0.1)
def update_data(attrname, ols, new):
a = A.value
b = B.value
x = np.array([-10., -8., -7., -2., 0., 1., 2., 5., 7., 9.])
y = np.array([-15., -12., -9., -5., 1., 4., 6., 7., 9., 12.])
z = f(x, y, a, b)
source.data = dict(X = x, Y = y, Z = z, color = colors[task_color.searchsorted(z)])
for w in [A, B]:
w.on_change('value', update_data)
inputs = widgetbox(A, B)
curdoc().add_root(row(inputs, plot))
curdoc().title = "My test"
