polar_opts

以下是关于polar_opts的介绍和演示：

polar_opts是pyecharts中极坐标图的配置项，可以通过设置polar_angleaxis_opts和polar_radiusaxis_opts来调整极坐标图的角度轴和半径轴的样式和属性。例如，可以通过设置polar_angleaxis_opts的boundary_gap属性来控制角度轴的起始位置和结束位置是否留白，还可以通过设置polar_radiusaxis_opts的min和max属性来控制半径轴的最小值和最大值。

以下是一个简单的例子，展示如何使用polar_opts来绘制一个极坐标图：

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

data = [("A", 10), ("B", 20), ("C", 30), ("D", 40), ("E", 50)]
angle_data = [item[0] for item in data]
radius_data = [item[1] for item in data]

polar = (
    Polar()
    .add("", [list(z) for z in zip(angle_data, radius_data)])
    .set_global_opts(title_opts=opts.TitleOpts(title="极坐标图"))
    .set_series_opts(label_opts=opts.LabelOpts(is_show=False))
    .set_colors(["#FF3333", "#FFFF33", "#33FF33", "#33FFFF", "#3333FF"])
    .set_polar(
        radius="60%",
        center=["50%", "50%"],
        start_angle=0,
        split_number=5,
        name_gap=20,
        boundary_gap=True,
        scale_tick=1,
        area_color_opacity=0.5,
        areastyle_opts=opts.AreaStyleOpts(opacity=0.5),
        angleaxis_opts=opts.AngleAxisOpts(
            boundary_gap=True,            start_angle=0,
            min_interval=10,
            max_interval=30,
            axislabel_opts=opts.LabelOpts(is_show=True, color="#333"),
            axisline_opts=opts.LineOpts(is_show=True, linestyle="dashed", color="#aaa"),
            axistick_opts=opts.AxisTickOpts(is_show=True, length=5, linestyle="solid", color="#aaa"),
            splitline_opts=opts.SplitLineOpts(is_show=True, linestyle="dashed", color="#aaa"),
        ),
        radiusaxis_opts=opts.RadiusAxisOpts(
            min_=0,
            max_=50,
            interval=10,
            axislabel_opts=opts.LabelOpts(is_show=True, color="#333"),
            axisline_opts=opts.LineOpts(is_show=True, linestyle="dashed", color="#aaa"),
            axistick_opts=opts.AxisTickOpts(is_show=True, length=5, linestyle="solid", color="#aaa"),
            splitline_opts=opts.SplitLineOpts(is_show=True, linestyle="dashed", color="#aaa"),
        ),
    )
)
