今天小编来给大家介绍一下如何在Pyecharts当中画出炫酷的图表，通过该模块当中的一系列设置，本文我们大致会介绍pyecharts当中的

Theme图表背景

Pyecharts模块内部内置了10多种不同风格的图表绘制样式，分别是

LIGHT = "light" DARK = "dark" WHITE = "white" CHALK: str = "chalk" ESSOS: str = "essos" INFOGRAPHIC: str = "infographic" MACARONS: str = "macarons" PURPLE_PASSION: str = "purple-passion" ROMA: str = "roma" ROMANTIC: str = "romantic" SHINE: str = "shine" VINTAGE: str = "vintage" WALDEN: str = "walden" WESTEROS: str = "westeros" WONDERLAND: str = "wonderland" HALLOWEEN: str = "halloween" 

我们依次来看一下每一种风格出来的样子，这次我们用到的数据集依然是Pyecharts模块当中内置的模块,当然我们首先需要导入相对应的模块

from pyecharts import options as opts from pyecharts.charts import Bar, Page from pyecharts.faker import Collector, Faker from pyecharts.globals import ThemeType

• Light

c = ( Bar(init_opts=opts.InitOpts(theme=ThemeType.LIGHT))

        .add_yaxis("商家B", Faker.values())
        .add_yaxis("商家C", Faker.values())
        .add_yaxis("商家D", Faker.values())

图片带有背景图

我们同时还能为自己绘制的图表配上自带的背景图片

c = (
    Bar(
        init_opts=opts.InitOpts(
            bg_color={"type": "pattern", "image": JsCode("img"), "repeat": "no-repeat"}
        )
    )
    .add_xaxis(Faker.choose())
    .add_yaxis("商家A", Faker.values())
    .add_yaxis("商家B", Faker.values())
    .set_global_opts(
        title_opts=opts.TitleOpts(
            title="Bar-背景图基本示例",
            subtitle="我是副标题",
            title_textstyle_opts=opts.TextStyleOpts(color="white"),
        )
    )
)
c.add_js_funcs( """
    var img = new Image(); img.src = 'https://t7.baidu.com/it/u=2638406194,523661981&fm=193&f=GIF';
    """ )
c.render("柱状图-自带背景图.html")

output

好吧，最后一张稍微有点丑，但是读者朋友们可以替换成自己喜欢的背景图片，说不定会非常的好看。

所以看了这么多张图之后，你们最喜欢哪种风格的呢？评论区留言。
