无法正确设置plot plot yaxis范围

Question

您好，我有一个问题，使线条图显示正确。我在一个图形上有两个轴和5个线状图。无法设置第一个y轴限制。我尝试将range属性设置为[0,2]，但是它什么也不做，并且继续从-2到4显示。我希望直线线状图直接覆盖在其他4个线状图的顶部，但我不知道为什么x轴从-5开始。有人能帮助解决这个问题吗？

fig = go.Figure()

xs = np.linspace(0,12.5,plot_df.shape[0])

for cn in plot_df.columns:
    ys = plot_df[cn].to_numpy()
    fig.add_trace(go.Scatter(x=xs, y=ys,
                        mode='lines',
                        name=cn)
                        )
    
fig.add_trace(go.Scatter(x=xs, y=xs,
                    mode='lines',
                    name='mob. grad', yaxis="y2")
                    )

fig.update_layout(
        title = "UV and Mobile phase trace of {}".format(field_dict['sample_name']),
        xaxis = dict(
            title = "Minutes",
            domain=[0.2, 1]
        ),
        yaxis = dict(
        scaleanchor = "x",
        title = "UV Abs",
        range = [0,2],
        position = 0.19
        ),
        yaxis2 = dict(
        title = "Mobile Phase (%)",
        anchor="free",
        domain=[0.1,1],
        overlaying="y",
        side="left",
        position=0.08,
        range=[0,100])

    )
fig.show()

我刚刚删除了scaleanchor = "x"，它正常地显示了。
