python - 在Python中以绘图方式勾勒出绘图区域

Question

我已经做了一个图，例如:

import plotly.plotly as py
import plotly.graph_objs as go

trace1 = go.Scatter(
    x=[1, 2, 3, 4, 5, 6, 7],
    y=[7, 6, 5, 4, 3, 2, 1]
)
trace2 = go.Scatter(
    x=[1, 2, 3, 4, 5, 6, 7, 8],
    y=[1, 2, 3, 4, 5, 6, 7, 8]
)
data = [trace1, trace2]
layout = dict(xaxis = dict(title = 'T (K)', showgrid=False, ticks='inside'),
                yaxis = dict(title = 'normalized intensity', showgrid=False, ticks='inside'),
                font=dict(size=18),
                )
fig = go.Figure(data=data, layout=layout)
py.iplot(fig, auto_open=True, filename='test_fig.png')
py.image.save_as(fig, filename='test_fig.png')

该图看起来像:



我想要一个绘图区的轮廓，如下所示:



但到目前为止，我仍无法从plot.ly文档中得出答案。这可能吗？

Answer 1

您所需要做的就是找到另一个隐藏良好的“Plotly”属性。在这种情况下，它是 mirror 。

mirror (enumerated: True | "ticks" | False | "all" | "allticks" )

Determines if the axis lines or/and ticks are mirrored to the opposite side of the plotting area. If "True", the axis lines are mirrored. If "ticks", the axis lines and ticks are mirrored. If "False", mirroring is disable. If "all", axis lines are mirrored on all shared-axes subplots. If "allticks", axis lines and ticks are mirrored on all shared-axes subplots.

添加

mirror=True,
ticks='outside',
showline=True,

到您的 xaxis和 yaxis dicts，您将得到以下图形。
