安装pyecharts
pip install pyecharts -U
本次使用jupyter notebook编写代码
折线图
# 引入相关包from pyecharts.faker import Faker #faker数据构造器from pyecharts import options as optsfrom pyecharts.charts import Line
(Line().add_xaxis(Faker.choose()).add_yaxis('组A', Faker.values()).add_yaxis('组B', Faker.values()).set_global_opts(title_opts=opts.TitleOpts(title='基本折线图'))).render_notebook()
阶梯图
在绘制折线图时，添加Y轴数据时设置is_step参数为True，就能得到阶梯图
(Line().add_xaxis(Faker.days_attrs).add_yaxis('', Faker.days_values, is_step=True).set_global_opts(title_opts=opts.TitleOpts(title='阶梯图'))).render_notebook()
平滑曲线图
在绘制折线图时，添加Y轴数据时设置is_smooth参数为True，就能得到平滑曲线图
(Line().add_xaxis(Faker.days_attrs).add_yaxis('', Faker.days_values, is_smooth=True).set_global_opts(title_opts=opts.TitleOpts(title='平滑曲线图'))).render_notebook()
面积图
在绘制折线图时，添加Y轴数据时设置areastyle_opts=AreaStyleOpts(opacity=**)
opacity=0.5，设置面积透明度
(Line().add_xaxis(Faker.choose()).add_yaxis('组A', Faker.values(), areastyle_opts=opts.AreaStyleOpts(opacity=0.5)).add_yaxis('组B', Faker.values(), areastyle_opts=opts.AreaStyleOpts(opacity=0.5)).set_global_opts(title_opts=opts.TitleOpts(title='基本面积图'))).render_notebook()
K线图
from pyecharts.charts import Candlestick#构造数据x_data = ["-10-24", "-10-25", "-10-26", "-10-27"]y_data = [[20, 28, 10, 35], [40, 35, 30, 55], [33, 38, 33, 40], [40, 38, 32, 42]]#绘图(Candlestick().add_xaxis(x_data).add_yaxis(series_name='', y_axis=y_data)).render_notebook()
常用配置项
全局配置项
提示框配置项：TooltipOpts
(Line().add_xaxis(Faker.choose()).add_yaxis('组A', Faker.values()).add_yaxis('组B', Faker.values()).set_global_opts(tooltip_opts=opts.TooltipOpts(trigger='axis'))).render_notebook()
视觉映射配置项：VisualMapOpts
(Line().add_xaxis(aqi_data['日期'].tolist()).add_yaxis('', aqi_data['AQI'].tolist(), is_smooth=True,is_symbol_show=False).set_global_opts(title_opts=opts.TitleOpts(title='空气质量指数'),tooltip_opts=opts.TooltipOpts(trigger='axis'),visualmap_opts=opts.VisualMapOpts(pos_top="10",pos_right="10",is_piecewise=True,pieces=[{"min": 0, "max": 50, "color": "#096"},{"min": 50, "max": 100, "color": "#ffde33"},{"min": 100, "max": 150, "color": "#ff9933"},{"min": 150, "max": 200, "color": "#cc0033"},{"min": 200, "max": 300, "color": "#660099"},{"min": 300, "color": "#7e0023"},],out_of_range={"color": "#999"},),)).render_notebook()
其他配置项
折线样式：LineStyleOpts, ItemStyleOpts
(Line().add_xaxis(Faker.choose()).add_yaxis('组A', Faker.values(),symbol='circle',#标记类型：'circle', 'rect', 'roundRect', 'triangle'等symbol_size=20,linestyle_opts=opts.LineStyleOpts(color="red", width=4, type_="dashed"),itemstyle_opts=opts.ItemStyleOpts(border_width=3, border_color="pink", color="blue"),)).render_notebook()
