如何为一张图创建双轴

Question

我试图让两个 y 轴具有相同的 x 轴。

这是我尝试过的。但自杀率并未显示在图表上。 我对此很陌生，所以我想知道是否有人能发现它为什么不显示。 图片应该是这样的，自杀率为红色，信任度为蓝色，国家为 x 轴

def suicidevstrustcountryplot(dat):
    
    # Does income index change trust for female led countries?
    # dat.plot(x ='Country', y='Income', kind = 'line')
    # plt.show()
    # create figure and axis objects with subplots()
    fig,ax = plt.subplots()
    # make a plot
    ax.plot(dat.Country, dat.Trust, color="red", marker="o")
    # set x-axis label
    ax.set_xlabel("Country",fontsize=14)
    for label in ax.get_xticklabels():
      label.set_rotation(90)
      label.set_ha('right')
    # set y-axis label
    ax.set_ylabel("Trust",color="red",fontsize=14)
    # twin object for two different y-axis on the sample plot
    ax2=ax.twinx()
    # make a plot with different y-axis using second axis object
    ax2.plot(dat.Country, dat.Trust,color="blue",marker="o")
    ax2.set_ylabel("Suicide rate",color="blue",fontsize=14)
    plt.show()
    # save the plot as a file
