如何使 plotly.express.timeline 重叠条可见 [英] How to get plotly.express.timeline overlapped bars to be visible

问题描述

我想知道是否有人有解决重叠时间轴栏的方法?

I'd like to know if anyone has a solution to overlapping timeline bars?

import plotly.express as px
import pandas as pd

df = pd.DataFrame([
    dict(Task="Job A", Start='2009-01-01', Finish='2009-02-28', Resource="Alex"),
    dict(Task="Job B", Start='2009-02-25', Finish='2009-04-15', Resource="Alex"),
    dict(Task="Job C", Start='2009-02-23', Finish='2009-05-23', Resource="Max"),
    dict(Task="Job D", Start='2009-02-20', Finish='2009-05-30', Resource="Max")
])

fig = px.timeline(df, x_start="Start", x_end="Finish", y="Resource", color="Resource")
fig.show()

在图片中很难看到:

• 工作 A 结束/工作 B 开始的地方
• 作业 D 根本不可见

有什么建议吗?

推荐答案

我经常发现为某些类别分配不同的 width 有助于使整个内容更易于阅读.因此，在您的情况下，我会在您的 df 中包含一列，其中指定了这一列，然后使用以下方法编辑该图:

I often find that assigning different width to some of the categories helps make the whole thing easier to read. So in your case I would include a column in your df where this is specified, and then edit the figure using:

for i, d in enumerate(fig.data):
    d.width = df[df['Task']==d.name]['width']

剧情:

import plotly.express as px
import pandas as pd

resource = ['Alex', 'Max']
df = pd.DataFrame([
    dict(Task="Job A", Start='2009-01-01', Finish='2009-02-28', Resource="Alex", width = 0.5),
    dict(Task="Job B", Start='2009-02-25', Finish='2009-04-15', Resource="Alex", width = 0.2),
    dict(Task="Job C", Start='2009-02-23', Finish='2009-05-23', Resource="Max", width = 0.5),
    dict(Task="Job D", Start='2009-02-20', Finish='2009-05-30', Resource="Max", width = 0.2)
])

fig = px.timeline(df, x_start="Start", x_end="Finish", y="Resource", color="Task")

for i, d in enumerate(fig.data):
    d.width = df[df['Task']==d.name]['width']
fig.show()
