python可视化pyechart折线图标签重叠

如何解决子图标签重叠的问题？
以及能否让图形中的这几个值不显示出来

Line1 = (
    Line(init_opts=opts.InitOpts(width="1000px", height="200px"))
    .add_xaxis(xaxis_data = Liquor['date']) 
    .add_yaxis(
        series_name="五粮液",
        y_axis=Liquor['R（五粮液）'],
        symbol="triangle",
        symbol_size=3,
    )
    .set_global_opts(
        title_opts=opts.TitleOpts(title="酒类行业股票收益率走势"),
        xaxis_opts=opts.AxisOpts(type_="category", boundary_gap=False),
    )
)
Line2 = (
    Line(init_opts=opts.InitOpts(width="1000px", height="200px"))
    .add_xaxis(xaxis_data = Liquor['date']) 
    .add_yaxis(
        series_name="茅台",
        y_axis=Liquor['R（茅台）'],
        symbol_size=3,
    )
    .set_global_opts(
        #title_opts=opts.TitleOpts(title="茅台收益率走势"),
        xaxis_opts=opts.AxisOpts(type_="category", boundary_gap=False),
    )
)
Line3 = (
    Line(init_opts=opts.InitOpts(width="1000px", height="200px"))
    .add_xaxis(xaxis_data = Liquor['date'])  
    .add_yaxis(
        series_name="青岛啤酒",
        y_axis=Liquor['R（青岛啤酒）'] ,
        symbol="diamond",
        symbol_size=3,   
    )   
    .set_global_opts(
        #title_opts=opts.TitleOpts(title="青岛啤酒收益率走势"),
        xaxis_opts=opts.AxisOpts(type_="category", boundary_gap=False),
    )
)
# 把上面生成的三个图放进grid中并通过pos_top，pos_bottom, pos_left, pos_right设置其位置
grid = (
    Grid()
    .add(Line1, grid_opts=opts.GridOpts(pos_top='7%', pos_bottom="60%"))
    .add(Line2, grid_opts=opts.GridOpts(pos_top='40%', pos_bottom="30%"))
    .add(Line3, grid_opts=opts.GridOpts(pos_top='70%', pos_bottom="0%"))
    )
# 生成到本地网页形式打开，也可自己设置保存成png图片，网页的使用更方便
grid.render("股票收益率走势折线图.html")

.add_xaxis(xaxis_data = Liquor['date']) 中加一个 is_label_show=False，就不显示标签了
.legend(is_show=False)，就不显示图例了
