【Python】pygal初步使用

import pygal

year_data = [str(i) for i in range(2011,2020)]
java_data = [17.89,18.29,20.45,19.28,20.35,21.23,19.98,20.23,19.5,20.0]
python_data = [4.89,4.29,4.45,4.28,5.35,6.23,6.98,6.23,6.5,6.0]

#創建圖
bar = pygal.Bar()
bar.title = 'Java與Python歷年的市場份額'

#添加數據
bar.add('Java語言的市場份額',java_data)
bar.add('Python語言的市場份額',python_data)
#配置
bar.x_labels = year_data
bar.x_title = '年份'
bar.y_title = '市場份額'

bar.x_label_rotation = 45
bar.legend_at_bottom = True

#輸出到圖片
bar.render_to_file("language.svg")
