plotly：水平条形图无法识别/显示trace2

如何解决plotly：水平条形图无法识别/显示trace2

我有一个用于水平条形图的图形组件，它包含在 callback 函数中并返回一个图形。

trace1 = go.Bar(
            x = [-2,-1.5,-1.2,-1,-0.5],y = ["C","0","I","D","R"],orientation = "h",marker = {
                "color": 'rgba(58,71,80,0.6)'
            },)

        trace2 = go.Bar(
            x = [2.2,1.8,1.3,0.9,0.5],marker = {
                "color": 'rgba(246,78,139,yaxis = "y2"
        )

        data = Data([trace1,trace2])

        layout = {
                    "xaxis": {'title': 'Percentage change','range': [-3,3]},"title": "Diagram","width": 862,"height": 680,"barmode": "stack","autosize": True,"showlegend": False,}

        return{'data':data,'layout':layout}

我的情节没有绘制条形图的反面。基本上，我想使用颜色来分隔 0 两侧的值。
