范围滑块标签未显示(标记)

Range Slider Labels are not showing (marks)

    data = [[30, 100], [31, 200], [32, 80], [33, 90], [34, 25], [35, 125],[36, 130],[37, 159],
           [38, 60]]
    df = pd.DataFrame(data, columns = ['week', 'orders'])

    html.Div([
    html.H3('Week Range'),
    dcc.RangeSlider(
        id='slider',
        min=df["week"].min(),
        max=df["week"].max(),
        value=[30, 38],
        step=None,
        marks={int(i):int(i) for i in list(df["week"].unique())}
    )])

找了很多都没有找到这个RangeSlider标签为什么不显示,查看附图我们会发现滑块的两端有3和8,我认为这是左边的数字第一周 = 30“3”,最后一周的最后一个数字 = 38“8”

    data = [[30, 100], [31, 200], [32, 80], [33, 90], [34, 25], [35, 125],[36, 130],[37, 159],
       [38, 60]]
df = pd.DataFrame(data, columns = ['week', 'orders'])

html.Div([
html.H3('Week Range'),
dcc.RangeSlider(
    id='slider',
    min=df["week"].min(),
    max=df["week"].max(),
    value=[30, 38],
    step=None,
    marks={int(i):str(i) for i in list(df["week"].unique())}
)]),html.Br(),

第二个图表 div 刚好在 RangeSlider 下方的问题导致几乎显示标签区域不显示,因此断线将 100% 解决问题
