Plotly漏斗 - 不想显示“总百分比”，但想要“初始百分比”和“前一百分比”

Question

在下面的图片中，你可以看到鼠标悬停时显示了“总数的百分比”。这个数字是所有层级加起来的百分比，但在这个漏斗图中其实并不重要。

下面是生成悬停信息的代码：

def create_engagement_figure(funnel_data=[]):

    fig = go.Figure(
        go.Funnel(
            y=funnel_data["Title"],
            x=funnel_data["Count"],
            textposition="auto",
            textinfo="value+percent initial+percent previous",
            # opacity=0.65,
            marker={
                "color": [
                    "#4F420A",
                    "#73600F",
                    "#947C13",
                    "#E0BD1D",
                    "#B59818",
                    "#D9B61C",
                ],
                "line": {
                    "width": [4, 3, 2, 2, 2, 1],
                    "color": ["wheat", "wheat", "wheat", "wheat"],
                },
            },
            connector={"line": {"color": "#4F3809", "dash": "dot", "width": 3}},
        )
    )
    fig.update_traces(texttemplate="%{value:,d}")
    fig.update_layout(
        margin=dict(l=20, r=20, t=20, b=20),
    )

    return fig

特别是这一行：

textinfo="value+percent initial+percent previous",

我试过：

textinfo="value+percent",

还有：

textinfo="value",

但无论怎么改，还是会显示“总数的百分比”。请问有没有办法通过plotly库去掉这个显示，这样我就不需要自己去做一个自定义的悬停信息？因为自定义悬停信息会有问题，因为这段代码会根据传入的数据框生成多个层级的漏斗图。

不太相关的，这里是其余的代码：

def engagement_funnel_chart(daterange, countries_list):

    LR = metrics.get_totals_by_metric(daterange, countries_list, stat="LR")
    PC = metrics.get_totals_by_metric(daterange, countries_list, "PC")
    LA = metrics.get_totals_by_metric(daterange, countries_list, stat="LA")
    GC = metrics.get_totals_by_metric(daterange, countries_list, "GC")

    funnel_data = {
        "Title": [
            "Learners Reached",
            "Puzzle Completed",
            "Learners Acquired",
            "Game Completed",
        ],
        "Count": [LR, PC, LA, GC],
    }
    fig = create_engagement_figure(daterange, countries_list, funnel_data)
    st.plotly_chart(fig, use_container_width=True)

你可以自定义 hoverinfo 属性（就像 textinfo 一样，不需要完全重写 hovertemplate）。默认值是 'all'，这对应于标志列表：

'x+y+text+percent initial+percent previous+percent total'

如果你想去掉 percent total 这个标志，比如说：

fig = go.Figure(
    go.Funnel(
        y = ["Website visit", "Downloads", "Potential customers", "Requested price", "Finalized"],
        x = [39, 27.4, 20.6, 11, 2],
        textposition="auto",
        textinfo="value+percent initial+percent previous",

        hoverinfo='x+y+text+percent initial+percent previous',

        # opacity=0.65,
        marker={
            "color": [
                "#4F420A",
                "#73600F",
                "#947C13",
                "#E0BD1D",
                "#B59818",
                "#D9B61C",
            ],
            "line": {
                "width": [4, 3, 2, 2, 2, 1],
                "color": ["wheat", "wheat", "wheat", "wheat"],
            },
        },
        connector={"line": {"color": "#4F3809", "dash": "dot", "width": 3}},
    )
)
