我正在尝试使用 plotly 库和 我想设置每行的特定宽度。
这是我的代码。
x_link = [125, 257, None, 125, 787, None]
y_link = [383, 588, None, 383, 212, None]
z_link = [65, 85, None, 65, 526, None]
link_size = [3,6]
trace1= go.Scatter3d(
x = x_link,
y = y_link,
z = z_link,
line=dict(
color='#0061ff',
width=link_size
)
)
但它引发了这个错误。
Invalid value of type 'builtins.list' received for the 'width' property of scatter3d.line Received value: [3, 6]
The 'width' property is a number and may be specified as: - An int or float in the interval [0, inf]
那么，有没有办法设置每行的具体宽度呢？
谢谢。
请您参考如下方法:
您将必须为您的数据集添加单独的跟踪才能执行此操作，因为line=dict(width) 只需要一个单个参数而不是某种数组。对于更大的数据集，这可能是大量工作。但是，如果您将数据集从列表更改为列表列表，您可以考虑更多数据点.因此，通过一些数据操作，您可以将其变为:
x_link = [125, 257, None, 125, 787, None]
y_link = [383, 588, None, 383, 212, None]
z_link = [65, 85, None, 65, 526, None]
进入这个:
x_link = [[125, 257, None], [125, 787, None]]
y_link = [[383, 588, None], [383, 212, None]]
z_link = [[65, 85, None], [65, 526, None]]
并运行这段代码:
import plotly.graph_objects as go
from plotly.offline import init_notebook_mode, iplot
x_link = [[125, 257, None], [125, 787, None]]
y_link = [[383, 588, None], [383, 212, None]]
z_link = [[65, 85, None], [65, 526, None]]
# figure formatting
colors=['red', 'green']
link_size = [2,12]
# make multiple traces
traces={}
for i in range(0, len(x_link)):
traces['trace_' + str(i)]=go.Scatter3d(x = x_link[i],
y = y_link[i],
z = z_link[i],
line=dict(
color=colors[i],
width=link_size[i]))
data=list(traces.values())
# build and plot figure
fig=go.Figure(data)
fig.show()
得到这个图:
