Question

我已经在Jupyter笔记本中的情节示例页面here上复制并粘贴了确切的代码 - 除了我在离线模式下运行，所以我的import语句如下所示：

from plotly.offline import init_notebook_mode
import plotly.offline as py
import plotly.figure_factory as ff
from plotly import graph_objs as go
init_notebook_mode()

生成的绘图具有没有宽度的漏斗形状。

示例代码是否已损坏？我认为它与定义shape和path变量有关，但打印这些值看起来合理。

或者，似乎不太可能，但离线模式可能会搞砸了什么？

链接示例中的完整代码如下：

values = [13873, 10553, 5443, 3703, 1708]
phases = ['Visit', 'Sign-up', 'Selection', 'Purchase', 'Review']

n_phase = len(phases)
plot_width = 400
section_h = 100
section_d = 10
unit_width = plot_width / max(values)
phase_w = [int(value * unit_width) for value in values]
height = section_h * n_phase + section_d * (n_phase - 1)
shapes = []
label_y = []

for i in range(n_phase):
        if (i == n_phase-1):
                points = [phase_w[i] / 2, height, phase_w[i] / 2, height - section_h]
        else:
                points = [phase_w[i] / 2, height, phase_w[i+1] / 2, height - section_h]

        path = 'M {0} {1} L {2} {3} L -{2} {3} L -{0} {1} Z'.format(*points)

        shape = {
                'type': 'path',
                'path': path,

                }
        }
        shapes.append(shape)

        # Y-axis location for this section's details (text)
        label_y.append(height - (section_h / 2))

        height = height - (section_h + section_d)

# For phase names
