python - 有没有办法改变散点图上的原点轴(零线)？

Question

有没有办法改变散点图上的轴？假设将轴从 (0,0) 即(零线)移动到 (3,3) 之类的位置并制作象限图

我尝试将“xaxis”和“yaxis”上的“zeroline”值设置为False，然后从“shapes”的两个轴上绘制两条恒定线。但我想知道是否有任何方法可以更改原点轴。

Here's the example in the image

import plotly.graph_objs as go
import plotly
import plotly.io as pio
trace0 = go.Scatter(
    x=[7],
    y=[7.5],
)
data = [trace0]
layout = {
    'xaxis': {
        'zeroline': False,
        'dtick': 1,
    },
    'yaxis': {
        'zeroline': False,
        'dtick': 1,

    },
    'shapes': [
        {
            'type': 'line',
            'x0': 5,
            'y0': 0,
            'x1': 5,
            'y1': 10,
            'line': {
                'width': 1,
            },
        },
        {
            'type': 'line',
            'x0': 0,
            'y0': 5,
            'x1': 10,
            'y1': 5,
            'line': {
                'width': 1
            },
        },
    ]
}
fig = {
    'data': data,
    'layout': layout,
}
plotly.offline.plot(fig)
pio.write_image(fig, 'images/test.png')

Answer 1

如果您运行 help(fig['layout']['xaxis']) 您会看到 zeroline 的唯一选项是:

 zeroline
     Determines whether or not a line is drawn at along the
     0 value of this axis. If True, the zero line is drawn
     on top of the grid lines.
 zerolinecolor
     Sets the line color of the zero line.
 zerolinewidth
     Sets the width (in px) of the zero line.

所以如果你的方法是......

setting the "zeroline" value on both "xaxis" and "yaxis" to False and then drawing two constant lines across both the axes from 'shapes'.

...适合您，我真的认为这是您最好的选择。
