如何制作没有标记点的 Plotly 散点图?
How to make a Plotly scatter plot without marker dots?
我正在尝试创建一系列带阴影线的方形 PNG - 类似于页面末尾 here 显示的样本。
这些不能在网络上使用 - 所以我认为使用 textures.js 会太迂回,我偶然发现了 Plotly,特别是 this
我做到了这一点
import plotly.express as px
import plotly.graph_objects as go
xy = [
[0, 0], [1, 0], [1, 1], [0, 1], [0, 0]
]
fig = go.Figure(go.Scatter(x=[ co[0] for co in xy ], y=[ co[1] for co in xy ],
fill="toself", marker={'size': 0 }
))
fig.update_layout(showlegend=False)
fig.update_xaxes(visible=False)
fig.update_yaxes(visible=False)
img_bytes = fig.to_image(format="png")
fig.write_image("foo.png")
生成这个:
但我努力不显示矩形角上的点。
我该怎么做?我知道没有点的散点图有点荒谬,所以如果有更清晰的解决方案也很好。
(我想我会弄清楚如何没有线条和背景以及如何用影线填充它 - 但也欢迎提供帮助)
尝试使用标记不透明度:
fig = go.Figure(go.Scatter(x=[ co[0] for co in xy ], y=[ co[1] for co in xy ],
fill="toself", marker={'opacity': 0}
))
绘制无线无标记
fig = go.Figure(go.Scatter(x=[ co[0] for co in xy ], y=[ co[1] for co in xy ],
fill="toself", mode='text'
))
不带标记但带线的绘图
fig = go.Figure(go.Scatter(x=[ co[0] for co in xy ], y=[ co[1] for co in xy ],
fill="toself", mode='lines'
))
只需添加以下行:
mode ="lines",
查看总代码:
import plotly.express as px
import plotly.graph_objects as go
xy = [ [0, 0], [1, 0], [1, 1], [0, 1], [0, 0]]
fig = go.Figure(go.Scatter(x=[ co[0] for co in xy ], y=[ co[1] for co in xy ],
fill="toself",
mode ="lines",
# marker={'size': 0 }
))
fig.update_layout(showlegend=False)
fig.update_xaxes(visible=False)
fig.update_yaxes(visible=False)
img_bytes = fig.to_image(format="png")
fig.write_image("foo.png")
