Plotly:如何使用 plotly 作为 Pandas 的绘图后端来制作不同的图? [英] Plotly: How to make different plots using plotly as a plotting backend for pandas?
问题描述
将 plotly 设置为 pandas 的后端,您可以使用以下方法快速轻松地生成绘图:
Setting plotly as a backend for pandas, you can produce plots quickly and easily using:
df.plot()
如何使此设置生成线图以外的其他图?还有哪些其他选择?
How can you make this setup produce other plots than lineplots? And what other options are there?
推荐答案
您可以通过以下中的 kind
参数定义您想要生成的绘图类型:
You can define which plot type you'd like to produce through the kind
argument in:
df.plot(kind='line')
kind='line'
生成与问题中完全相同的图.有效选项是:
kind='line'
produces the very same plot as in the question. Valid options are:
['scatter', 'line', 'area', 'bar',
'barh', 'hist', 'box', 'violin',
'strip', 'funnel', 'density_heatmap',
'density_contour', 'imshow']
您可以通过运行轻松地研究它们:
You can easily study them all by running:
for k in kinds[:-1]:
df.plot(kind=k).show()
情节:
请注意,我使用了 kinds[:-1]
.这是因为 imshow
用于图像数据并且需要一个比 [1,2,3,4,5,6]
bit 的数据集>.请参考 this 和 使用来自熊猫数据帧的 imshow 绘制图像
Notice that I've used kinds[:-1]
. This is because imshow
is for image data and requires a dataset a bit more complicated than [1,2,3,4,5,6]
. Please refer to this and Plotting an image with imshow from a pandas dataframe
为了设置所有其他选项的标题和标题颜色,这里有一个完整的代码片段:
In order to set the titles and title colors for all other options, here's a complete code snippet:
import random
import pandas as pd
random.seed(123)
df = pd.DataFrame({'x':[1,2,3,4,5,6]})
pd.options.plotting.backend = "plotly"
kinds = ['scatter', 'line', 'area', 'bar', 'barh', 'hist', 'box', 'violin', 'strip', 'funnel', 'density_heatmap', 'density_contour', 'imshow']
for k in kinds[:-1]:
fig = df.plot(kind=k, title = k)
fig.update_layout(title = dict(font=dict(color='#EF553B')))
fig.show()
