pyecharts添加背景图片

可以通过在初始化时指定 background_image 参数来添加背景图片，示例代码如下：

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

bar = Bar()
bar.add_xaxis(['A', 'B', 'C'])
bar.add_yaxis('Series', [1, 3, 2])
bar.set_global_opts(
    title_opts=opts.TitleOpts(title='Title'),
    # 添加背景图片
    graphic_opts=[opts.GraphicImage(
        graphic_item=opts.GraphicItem(
            id_='background',
            right=50,
            bottom=50,
            z=10,
            bounding='raw',
            origin=[75, 75],
        ),
        graphic_image=opts.GraphicImageOpts(
            id_='background',
            graphic_type='image',
            graphic_image='path/to/image.jpg',
            graphic_size=[150, 150],
            graphic_left=-75,
            graphic_top=-75,
        ),
    )],
)
bar.render()
