我想创建一个棒棒糖图,上面有几个水平线段-https://python-graph-gallery.com/184-lollipop-plot-with-2-group。我想使用绘图,因为我更喜欢图形(易于交互),但是找不到简洁的方法。
有两个折线图(https://plot.ly/python/line-charts/),您可以在布局中添加线(https://plot.ly/python/shapes/#vertical-and-horizontal-lines-positioned-relative-to-the-axes),但是这两种解决方案都要求每个线段分别添加,大约需要4-8条线每个代码。虽然我可以对此进行循环,但如果有人可以将我指向带有内置矢量化功能的任何内容,例如matplotlib解决方案(第一个链接),我们将不胜感激!
编辑:还尝试了以下代码,首先将绘图设置为matplotlib,然后转换为plotly。线段在此过程中消失。开始认为这是不可能的。
mpl_fig = plt.figure()
# make matplotlib plot - WITH HLINES
plt.rcParams['figure.figsize'] = [5,5]
ax = mpl_fig.add_subplot(111)
ax.hlines(y=my_range, xmin=ordered_df['value1'], xmax=ordered_df['value2'],
color='grey', alpha=0.4)
ax.scatter(ordered_df['value1'], my_range, color='skyblue', alpha=1,
label='value1')
ax.scatter(ordered_df['value2'], my_range, color='green', alpha=0.4 ,
label='value2')
ax.legend()
# convert to plotly
plotly_fig = tls.mpl_to_plotly(mpl_fig)
plotly_fig['layout']['xaxis1']['showgrid'] = True
plotly_fig['layout']['xaxis1']['autorange'] = True
plotly_fig['layout']['yaxis1']['showgrid'] = True
plotly_fig['layout']['yaxis1']['autorange'] = True
# plot: hlines disappear :/
iplot(plotly_fig)
答案 0 :(得分:0)
Plotly没有为此类图表提供内置的矢量化功能,因为您可以轻松完成此操作,请根据您提供的链接查看我的示例:
import pandas as pd
import numpy as np
import plotly.offline as pyo
import plotly.graph_objs as go
# Create a dataframe
value1 = np.random.uniform(size = 20)
value2 = value1 + np.random.uniform(size = 20) / 4
df = pd.DataFrame({'group':list(map(chr, range(65, 85))), 'value1':value1 , 'value2':value2 })
my_range=range(1,len(df.index)+1)
# Add title and axis names
data1 = go.Scatter(
x=df['value1'],
y=np.array(my_range),
mode='markers',
marker=dict(color='blue')
)
data2 = go.Scatter(
x=df['value2'],
y=np.array(my_range),
mode='markers',
marker=dict(color='green')
)
# Horizontal line shape
shapes=[dict(
type='line',
x0 = df['value1'].loc[i],
y0 = i + 1,
x1 = df['value2'].loc[i],
y1 = i + 1,
line = dict(
color = 'grey',
width = 2
)
) for i in range(len(df['value1']))]
layout = go.Layout(
shapes = shapes,
title='Lollipop Chart'
)
# Plot the chart
fig = go.Figure([data1, data2], layout)
pyo.plot(fig)
结果是:
