pyechat 类传参可以是参数或者字典参数

5 分钟上手
首先开始来绘制你的第一个图表

from pyecharts.charts import Bar

bar = Bar()
bar.add_xaxis(["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"])
bar.add_yaxis("商家A", [5, 20, 36, 10, 75, 90])
# render 会生成本地 HTML 文件，默认会在当前目录生成 render.html 文件
# 也可以传入路径参数，如 bar.render("mycharts.html")
bar.render()


pyecharts 所有方法均支持链式调用。

from pyecharts.charts import Bar

bar = (
    Bar()
    .add_xaxis(["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"])
    .add_yaxis("商家A", [5, 20, 36, 10, 75, 90])
)
bar.render()


使用 options 配置项，在 pyecharts 中，一切皆 Options。

from pyecharts.charts import Bar
from pyecharts import options as opts

# V1 版本开始支持链式调用
# 你所看到的格式其实是 `black` 格式化以后的效果
# 可以执行 `pip install black` 下载使用
bar = (
    Bar()
    .add_xaxis(["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"])
    .add_yaxis("商家A", [5, 20, 36, 10, 75, 90])
    .set_global_opts(title_opts=opts.TitleOpts(title="主标题", subtitle="副标题"))
    
	# 或者直接使用字典参数
    # .set_global_opts(title_opts={"text": "主标题", "subtext": "副标题"})
)
bar.render()



class TitleOpts(BasicOpts):
    def __init__(
        self,
        title: Optional[str] = None,
        title_link: Optional[str] = None,
        title_target: Optional[str] = None,
        subtitle: Optional[str] = None,
        subtitle_link: Optional[str] = None,
        subtitle_target: Optional[str] = None,
        pos_left: Optional[str] = None,
        pos_right: Optional[str] = None,
        pos_top: Optional[str] = None,
        pos_bottom: Optional[str] = None,
        title_textstyle_opts: Union[TextStyleOpts, dict, None] = None,
        subtitle_textstyle_opts: Union[TextStyleOpts, dict, None] = None,
    ):
        self.opts: Sequence = [
            {
                "text": title,
                "link": title_link,
                "target": title_target,
                "subtext": subtitle,
                "sublink": subtitle_link,
                "subtarget": subtitle_target,
                "left": pos_left,
                "right": pos_right,
                "top": pos_top,
                "bottom": pos_bottom,
                "textStyle": title_textstyle_opts,
                "subtextStyle": subtitle_textstyle_opts,
            }
        ]
