【Python】太炫酷了，這里有一個(gè)用于制作數(shù)據(jù)面板大屏的Python模塊

• 用pandas以及hvPlot結(jié)合生成具有交互性的圖表
• 用Panel模塊生成小的組件，配合圖表進(jìn)行使用
• 制作一個(gè)數(shù)據(jù)可視化大屏來更好地呈現(xiàn)數(shù)據(jù)

pandas+hvPlot繪制圖表

我們首先導(dǎo)入一些要用到的模塊以及用pandas來讀取數(shù)據(jù)集，代碼如下

#?To?handle?data
import?numpy?as?np
import?pandas?as?pd

#?To?make?visualizations
import?hvplot.pandas
import?panel?as?pn;?pn.extension()
from?panel.template?import?DarkTheme

sales?=?pd.read_csv('games_sales.csv')
sales.plot(kind='line',?x='Year',?y='Units?sold(in?millions)',?color='orange',?grid=True,?title='Pokémon?Game?Sales');

output

pd.options.plotting.backend?=?'holoviews'

我們同樣來繪制如上所示的圖表，代碼如下

sales.plot(kind='line',?x='Year',?y='Units?sold(in?millions)',?color='orange',?grid=True,?title='Pokémon?Game?Sales')

output

salesplot?=?sales.plot(kind='line',?x='Year',?y='Units?sold(in?millions)',
???????????????????????color='orange',?grid=True,?title='Pokémon?Game?Sales',
???????????????????????hover=False)?*?\
????????????????sales.plot(kind='scatter',?x='Year',?y='Units?sold(in?millions)',
???????????????????????????color='#c70000',?hover_cols='Game')
salesplot

output

制作一個(gè)小組件

在上一期小編寫過的教程

【干貨原創(chuàng)】介紹一個(gè)Python模塊，Seaborn繪制的圖表也能實(shí)現(xiàn)動(dòng)態(tài)交互

pok_types?=?list(df.type_1.unique())
pok_type?=?pn.widgets.Select(name='Type',?options=pok_types)
pok_type

output

我們結(jié)合該組件來繪制圖表，代碼如下

viz0?=?data_pipeline[['pokedex_number',?'name',
??????????????????????'total_points']].hvplot(kind='table',title='Pokémons',
??????????????????????????????????????????????width=400,?height=400)
viz0

output

viz1?=?data_pipeline.hvplot(x='weight_kg',?y='height_m',?
?????????????????????by='type_2',?kind='scatter',?
?????????????????????hover_cols=['name',?'type_1',?'type_2'],
?????????????????????width=600,?height=400,grid=True,
?????????????????????title='Relationship?between?Weight?(kg)?and?Height?(m),?by?Type'
????????????????????)
viz1

output

另外我們也可以同樣來繪制一張柱狀圖，代碼如下

data_damage?=?data_pipeline.iloc[:,?-18:].mean().rename('Damage')
viz2?=?data_damage.hvplot(kind='bar',c='Damage',?
???????????????title='正在思考要取什么標(biāo)題會(huì)比較好......',?
???????????????rot=30,?shared_axes=False,
???????????????colorbar=True,?colormap='RdYlGn_r',?
???????????????)
viz2

output
