根据代码提示，Classic_fig未定义，所以我们需要先定义Classic_fig，或者将其从plot_options中删除。下面是两种修改方案：

方案一：定义Classic_fig

可以先定义Classic_fig，例如：

Classic_fig = plt.figure()
# 添加Classic_fig的子图等操作

然后再将Classic_fig添加到plot_options中，如下所示：

plot_options = {
    '1': Classic_fig,
    '2': MassFlowReport_fig,
    '3': Temperature_fig,
    '4': Pressure_food_fig
}

方案二：删除Classic_fig

如果不需要Classic_fig，可以将其从plot_options中删除，如下所示：

plot_options = {
    '2': MassFlowReport_fig,
    '3': Temperature_fig,
    '4': Pressure_food_fig
}

这样就可以避免Classic_fig未定义的错误了。
