如何使用Python的Pyecharts制作漂亮的River 主题河流图？
|
主题河流图（ThemeRiver）是一种用来展示时间序列数据的图表。因此，在数据分析中，主题河流图可能会被用来展示某一个变量随着时间变化的情况，或者用来展示多个变量之间的相互关系。例如，在金融领域中，主题河流图可以用来展示某只股票的价格随时间变化的情况；在气候学领域中，主题河流图可以用来展示某个城市的气温、湿度和降水量随时间变化的情况。 Python3 的 Pyecharts 制作 ThemeRiver（主题河流图） 时需要使用的设置参数和常用模板案例，可根据实际情况对案例中的内容进行调整即可。 Demo 举例主题河流图import pyecharts.options as opts from pyecharts.charts import ThemeRiver x_data = ["DQ", "TY", "SS", "QG", "SY", "DD"] y_data = [ ["2015/11/08", 10, "DQ"], ["2015/11/09", 15, "DQ"], ["2015/11/10", 35, "DQ"], ["2015/11/11", 38, "DQ"], ["2015/11/12", 22, "DQ"], ["2015/11/13", 16, "DQ"], ["2015/11/14", 7, "DQ"], ["2015/11/15", 2, "DQ"], ["2015/11/16", 17, "DQ"], ["2015/11/17", 33, "DQ"], ["2015/11/18", 40, "DQ"], ["2015/11/19", 32, "DQ"], ["2015/11/20", 26, "DQ"], ["2015/11/21", 35, "DQ"], ["2015/11/22", 40, "DQ"], ["2015/11/23", 32, "DQ"], ["2015/11/24", 26, "DQ"], ["2015/11/25", 22, "DQ"], ["2015/11/26", 16, "DQ"], ["2015/11/27", 22, "DQ"], ["2015/11/28", 10, "DQ"], ["2015/11/08", 35, "TY"], ["2015/11/09", 36, "TY"], ["2015/11/10", 37, "TY"], ["2015/11/11", 22, "TY"], ["2015/11/12", 24, "TY"], ["2015/11/13", 26, "TY"], ["2015/11/14", 34, "TY"], ["2015/11/15", 21, "TY"], ["2015/11/16", 18, "TY"], ["2015/11/17", 45, "TY"], ["2015/11/18", 32, "TY"], ["2015/11/19", 35, "TY"], ["2015/11/20", 30, "TY"], ["2015/11/21", 28, "TY"], ["2015/11/22", 27, "TY"], ["2015/11/23", 26, "TY"], ["2015/11/24", 15, "TY"], ["2015/11/25", 30, "TY"], ["2015/11/26", 35, "TY"], ["2015/11/27", 42, "TY"], ["2015/11/28", 42, "TY"], ["2015/11/08", 21, "SS"], ["2015/11/09", 25, "SS"], ["2015/11/10", 27, "SS"], ["2015/11/11", 23, "SS"], ["2015/11/12", 24, "SS"], ["2015/11/13", 21, "SS"], ["2015/11/14", 35, "SS"], ["2015/11/15", 39, "SS"], ["2015/11/16", 40, "SS"], ["2015/11/17", 36, "SS"], ["2015/11/18", 33, "SS"], ["2015/11/19", 43, "SS"], ["2015/11/20", 40, "SS"], ["2015/11/21", 34, "SS"], ["2015/11/22", 28, "SS"], ["2015/11/23", 26, "SS"], ["2015/11/24", 37, "SS"], ["2015/11/25", 41, "SS"], ["2015/11/26", 46, "SS"], ["2015/11/27", 47, "SS"], ["2015/11/28", 41, "SS"], ["2015/11/08", 10, "QG"], ["2015/11/09", 15, "QG"], ["2015/11/10", 35, "QG"], ["2015/11/11", 38, "QG"], ["2015/11/12", 22, "QG"], ["2015/11/13", 16, "QG"], ["2015/11/14", 7, "QG"], ["2015/11/15", 2, "QG"], ["2015/11/16", 17, "QG"], ["2015/11/17", 33, "QG"], ["2015/11/18", 40, "QG"], ["2015/11/19", 32, "QG"], ["2015/11/20", 26, "QG"], ["2015/11/21", 35, "QG"], ["2015/11/22", 40, "QG"], ["2015/11/23", 32, "QG"], ["2015/11/24", 26, "QG"], ["2015/11/25", 22, "QG"], ["2015/11/26", 16, "QG"], ["2015/11/27", 22, "QG"], ["2015/11/28", 10, "QG"], ["2015/11/08", 10, "SY"], ["2015/11/09", 15, "SY"], ["2015/11/10", 35, "SY"], ["2015/11/11", 38, "SY"], ["2015/11/12", 22, "SY"], ["2015/11/13", 16, "SY"], ["2015/11/14", 7, "SY"], ["2015/11/15", 2, "SY"], ["2015/11/16", 17, "SY"], ["2015/11/17", 33, "SY"], ["2015/11/18", 40, "SY"], ["2015/11/19", 32, "SY"], ["2015/11/20", 26, "SY"], ["2015/11/21", 35, "SY"], ["2015/11/22", 4, "SY"], ["2015/11/23", 32, "SY"], ["2015/11/24", 26, "SY"], ["2015/11/25", 22, "SY"], ["2015/11/26", 16, "SY"], ["2015/11/27", 22, "SY"], ["2015/11/28", 10, "SY"], ["2015/11/08", 10, "DD"], ["2015/11/09", 15, "DD"], ["2015/11/10", 35, "DD"], ["2015/11/11", 38, "DD"], ["2015/11/12", 22, "DD"], ["2015/11/13", 16, "DD"], ["2015/11/14", 7, "DD"], ["2015/11/15", 2, "DD"], ["2015/11/16", 17, "DD"], ["2015/11/17", 33, "DD"], ["2015/11/18", 4, "DD"], ["2015/11/19", 32, "DD"], ["2015/11/20", 26, "DD"], ["2015/11/21", 35, "DD"], ["2015/11/22", 40, "DD"], ["2015/11/23", 32, "DD"], ["2015/11/24", 26, "DD"], ["2015/11/25", 22, "DD"], ["2015/11/26", 16, "DD"], ["2015/11/27", 22, "DD"], ["2015/11/28", 10, "DD"], ] c=( ThemeRiver(init_opts=opts.InitOpts(width="900px", height="600px")) .add( series_name=x_data, data=y_data, singleaxis_opts=opts.SingleAxisOpts( pos_top="50", pos_bottom="50", type_="time" ), ) .set_global_opts( tooltip_opts=opts.TooltipOpts(trigger="axis", axis_pointer_type="line") ) # .render("主题河流图.html") ) c.render_notebook()  ThemeRiver：主题河流图基本设置class ThemeRiver(
