Random vertical lines extending to x-axis on line chart

#1

Hi

Does anyone know why I might be seeing these random vertical yellow lines on my line chart?

The trace that they are coming down from is this:

trace2 = go.Scatter(
    x = x1,
    y = y2,
    yaxis = 'y',
    line = dict(
        color=colors['price'],
        width=0.8,
    )
)

And the axis parameters from my figure are:

        yaxis=dict(
            color=colors['labels'],
            side='left',
            hoverformat='%',
            range=[0,1],
            showspikes=True,
            spikemode='toaxis',
            spikedash='solid',
            spikethickness=1,
            spikecolor=colors['spike'],
            showgrid=False,
            tickfont = dict(
                size=8
            ),
            tickformat='%',
        ),

        xaxis= dict(
            color=colors['labels'],
            showspikes=True,
            hoverformat='%d-%b-%y',
            spikemode='toaxis+across',
            spikedash='solid',
            spikethickness=1,
            spikecolor=colors['spike'],
        ),

Thanks
