我有这个回调函数，可以生成热图和可选的树状图。但是，在创建树状图时，该图缺少yticklabels。我希望标签显示在树状图的左侧或热图的右侧。

@app.callback(
    Output('peakAreas','figure'),[Input('b_peakAreas','n_clicks'),Input('table','derived_virtual_indices'),Input('checklist','value')]) def plot_0(n_clicks,ndxs,options):
    title = 'Heatmap'
    if n_clicks is None:
        return {}
    df = mint.crosstab.T.iloc[ndxs]
    df.index = [basename(i).replace('.mzXML','') for i in df.index]

    if 'normed' in options:
        df = df / df.max()
        title = f'Normalized {title}'



    if 'clustered' in options:
        D = squareform(pdist(df,metric='euclidean'))
        Y = linkage(D,method='complete')
        Z = dendrogram(Y,orientation='left',no_plot=True)['leaves']
        df = df.iloc[Z,:]
        dendro_side = ff.create_dendrogram(df,orientation='right')

    heatmap = go.Heatmap(z=df.values,x=df.columns,y=df.index,colorscale = 'Blues')

    if not 'dendrogram' in options:
        fig = go.Figure(heatmap)
        fig.update_layout(
            title={'text': title,},yaxis={'title': '','tickmode': 'array','automargin': True}) 
        return fig

    fig = go.Figure()

    for i in range(len(dendro_side['data'])):
            dendro_side['data'][i]['xaxis'] = 'x2'

    for data in dendro_side['data']:
        fig.add_trace(data)

    y_labels = heatmap['y']


    heatmap['y'] = dendro_side['layout']['yaxis']['tickvals']
    dendro_side['layout']['yaxis']['ticktext'] = y_labels

    fig.add_trace(heatmap)     

    fig.update_layout({'showlegend':False,'hovermode': 'closest'})
    fig.update_layout(
            title={'text': title,'automargin': True}) 


    fig.update_layout(xaxis2={'domain': [0,.1],'mirror': False,'showgrid': True,'showline': False,'zeroline': False,'showticklabels': False,'ticks':""})        

    fig.update_layout(xaxis={'domain': [.1,1],'showgrid': False,'showticklabels': True,'ticks':""})
    # Edit yaxis
    fig.update_layout(yaxis={'domain': [0,})

    fig.update_layout(yaxis_ticktext = y_labels)

    print(dendro_side.layout['yaxis'])
    return fig

当我绘制y轴布局时，我得到以下信息：

layout.YAxis({
    'mirror': 'allticks','rangemode': 'tozero','showline': True,'ticks': 'outside','ticktext': array(['SA1','SA3','SA2','SA4','CA1','CA2','CA3','CA4','EC2','EC4','EC1','EC3'],dtype=object),'tickvals': [5.0,15.0,25.0,35.0,45.0,55.0,65.0,75.0,85.0,95.0,105.0,115.0],'type': 'linear','zeroline': False
})

因此，对我来说，由于正确的数据存储在ticktext下，因此图形应该具有正确的标签。但是它没有出现。
