词云集中并减少图中随机定位的单词的重叠

Question

import plotly
import random
import plotly.graph_objects as go
from plotly.subplots import make_subplots   

random.seed(42) 

words = ['potato','hello','juvi']
colors = [plotly.colors.DEFAULT_PLOTLY_COLORS[random.randrange(1, 10)] for i in range(20)]
weights = [110,80,20]

data = go.Scatter(x=[random.random() for i in range(20)],
             y=[random.random() for i in range(20)],
             mode='text',
             text=words,
             marker={'opacity': 0.3},
             textfont={'size': weights,
                       'color': colors})

layout = go.Layout({'xaxis': {'showgrid': False, 'showticklabels': False, 'zeroline': False},
                'yaxis': {'showgrid': False, 'showticklabels': False, 'zeroline': False}})
fig = go.Figure(data=[data], layout=layout)

fig.show()

我有以下示例代码，它可以在绘图中生成词云，事情是，正如您所看到的，这些单词往往会超出图中给定的方块，关于如何将单词保留在蓝色方块内的任何想法。或者至少更靠近它的中心

Answer 1

发生这种情况是因为您将 20 个随机生成的 (x,y) 坐标传递给

go.Scatter

，但总共只有 3 个单词，因此绘图是根据您传递的坐标而不是位置来设置默认轴范围这 3 个字。

如果这不是故意的，那么我会假设您打算在 20 个坐标处从列表中随机选择 20 个单词，然后您将像这样修改代码：

import plotly
import random
import plotly.graph_objects as go
from plotly.subplots import make_subplots   

random.seed(42) 

words = ['potato','hello','juvi']
colors = [plotly.colors.DEFAULT_PLOTLY_COLORS[random.randrange(1, 10)] for i in range(20)]
weights = [110,80,20]

x = [random.random() for i in range(20)]
y = [random.random() for i in range(20)]
scatter_words = [random.choice(words) for i in range(20)]
scatter_weights = [random.choice(weights) for i in range(20)]
data = go.Scatter(x=x,
             y=y,
             mode='text',
             text=scatter_words,
             marker={'opacity': 0.3},
             textfont={'size': scatter_weights,
                       'color': colors})

layout = go.Layout({'xaxis': {'showgrid': False, 'showticklabels': False, 'zeroline': False},
                'yaxis': {'showgrid': False, 'showticklabels': False, 'zeroline': False}})
fig = go.Figure(data=[data], layout=layout)

fig.show()
