pychars的使用
1|0安装
pyecharts 兼容 Python2 和 Python3。目前版本为 0.1.2
pip install pyecharts
2|0入门
首先开始来绘制你的第一个图表
from pyecharts import Bar
bar = Bar("我的第一个图表", "这里是副标题")
bar.add("服装", ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"], [5, 20, 36, 10, 75, 90])
bar.show_config()
bar.render()
Tip： 可以按右边的下载按钮将图片下载到本地
add()
主要方法，用于添加图表的数据和设置各种配置项show_config()
打印输出图表的所有配置项render()
默认将会在根目录下生成一个 render.html 的文件，支持 path 参数，设置文件保存位置，如 render(r"e:\my_first_chart.html")，文件用浏览器打开。
默认的编码类型为 UTF-8，在 Python3 中是没什么问题的，Python3 对中文的支持好很多。但是在 Python2 中，编码的处理是个很头疼的问题，暂时没能找到完美的解决方法，目前只能通过文本编辑器自己进行二次编码，我用的是 Visual Studio Code，先通过 Gbk 编码重新打开，然后再用 UTF-8 重新保存，这样用浏览器打开的话就不会出现中文乱码问题了。
基本上所有的图表类型都是这样绘制的：
chart_name = Type()初始化具体类型图表。add()添加数据及配置项。render()生成 .html 文件。
2|1Bar（柱状图/条形图）
from pyecharts import Bar
bar = Bar("标记线和标记点示例")
