我仍在学习 iPython Notebook/Jupyter 以及如何使用 Bokeh 绘图。我正在使用这里的模型步骤：http: //nbviewer.ipython.org/github/bokeh/bokeh-notebooks/blob/master/tutorial/00%20-%20intro.ipynb# 但是我的代码在 In[ 上失败了13]：在他们的例子中。从散景它说：
In [13]:
from bokeh.models import Circle, HoverTool
from bokeh.palettes import Spectral6
renderer_source = ColumnDataSource(bubble_plot.get_1964_data())
def add_circles(plot):
plot = add_text(plot)
# Add the circle
circle_glyph = Circle(
x='fertility', y='life', size='population',
fill_color='region_color', fill_alpha=0.8,
line_color='#7c7e71', line_width=0.5, line_alpha=0.5)
circle_renderer = plot.add_glyph(renderer_source, circle_glyph)
# Add the hover (only against the circle and not other plot elements)
tooltips = "@index"
plot.add_tools(HoverTool(tooltips=tooltips, renderers=[circle_renderer]))
return plot
show(add_circles(get_plot()))
我的代码在第二步开始时失败。它如下，因为我使用的是我自己的数据：
In [96]:
from bokeh.models import Circle, HoverTool
from bokeh.palettes import Spectral6
from bokeh.plotting import *
In [97]:
renderer_source = ColumnDataSource(bubble_plot.get_df())
---------------------------------------------------------------------------
NameError Traceback (most recent call last)
<ipython-input-97-8659183dfef3> in <module>()
----> 1 renderer_source = ColumnDataSource(bubble_plot.get_df())
NameError: name 'bubble_plot' is not defined
为什么bubble_plot未定义，我该如何更改？这与他们的示例完全相同。到目前为止没有问题。谢谢！
