Plotly 交互式条形图在显示新轨迹之前不会删除以前的轨迹

Question

我正在尝试创建交互式 plotly 条形图。

select_feat = widgets.Dropdown(options=['overall_rating', 'potential'], description='Feature')

fig_1 = go.FigureWidget()

def response_1(feature):
    x = player_info.groupby(['player_name'])[feature].mean().nlargest(5)
    val = list(x.values)
    lab = list(x.index.values)
    fig_1.add_trace(go.Bar(x=lab, y=val))
    fig_1.update_layout(title='Top five playes by average')

VBox((fig_1, interactive(response_1, feature=select_feat)))

当我执行代码时，I got this plot for overall_rating. When chose option potential, I got this plot which has trace zero and one。梅西、C罗、伊涅斯塔在overall_rating和潜力上都位居前列。所以它为他们显示了两个栏。那么我能对只显示选定的与特征相关的轨迹做些什么呢？

我在 jupyter notebook 中离线使用 plotly。

Answer 1

通过将 add_trace 替换为 update_traces 并在 FigureWidget() 中添加 (data=[{'type':'bar'}]，我解决了问题。

Plotly interactive bar chart doesn't remove the previous trace before displaying new trace
