我有一个包含36列的数据框'df',这些列被绘制到单个绘图图表上,并使用以下代码以html格式显示。
import plotly.offline as py
import plotly.io as pio
pio.write_html(py.offline.plot([{
'x': df.index,
'y': df[col],
'name': col
}for col in trend_data.columns], filename=new_file_path))
我想遍历每一列并为每列创建一个子图。我已经尝试过;
from plotly.subplots import make_subplots
sub_titles = df.columns()
fig = make_subplots(rows=6, cols=6, start_cell="bottom-left", subplot_titles=sub_titles)
for i in df.columns:
fig.add_trace(i)
我创建了6行和列,因为这将给出36个图,并尝试将标头名称用作子图标题,但是我收到ValueError指出它期望使用二维字典列表。
此外,我尝试通过添加子图标题;
sub_titles = list(df)
fig = py.subplots.make_subplots(rows=6, cols=6, sub_titles=sub_titles)
这也会返回错误。感谢您的帮助。

有关如何使用子图的信息,请参见documentation。这可能有效:
更新(包括子图标题)
fig = py.subplots.make_subplots(rows=36, cols=1, subplot_titles=df.columns)
j = 1
for i in df.columns:
fig.add_trace(
go.Scatter(
{'x': df.index,
'y': df[i]}),
row=j, col=1)
j += 1
这将导致以下绘图(包含我的数据):
df = pd.DataFrame(np.random.randint(5, size=(5, 3)), columns=['one', 'two', 'three'])
