Python - 为绘图添加标记选项会产生错误

Question

您好我正在尝试使用标记每个选项为我的python图添加标记。当我添加这个时，我收到以下错误：ValueError：要解压缩的值太多。我不确定是什么导致它。以下是我的代码。

    temp = pd.read_csv(path+filename)
    temp=pd.DataFrame(temp).convert_objects(convert_numeric=True)

    fig,axes = plt.subplots(nrows=2,ncols=1)
    fig.subplots_adjust(hspace=1)
    fig = plt.figure()
    markers_on=[887,1661,2631,3406,4714,5606,6880,8332,9751]
    fig.subplots_adjust(hspace=.5)
    fig.suptitle('BC Attributes', fontsize=12)
    plt.subplot(3,1,1)
    plt.plot(temp.index,temp.BC_T_NODE0_CPU0_TEMP, marker='s', markevery=[887,1661,2631,3406,4714,5606,6880,8332,9751])
    plt.xlabel('Time')
    plt.ylabel('Node0 CPU0 Temp')
    plt.subplot(3,1,2)
    plt.plot(temp.index, temp.BC_T_NODE0_CPU1_TEMP, marker='s', markevery=[887,1661,2631,3406,4714,5606,6880,8332,9751])
    plt.xlabel('Time')
    plt.ylabel('Node0 CPU1 Temp')
    plt.subplot(3,1,3)
    plt.plot(temp.index, temp.BC_T_NODE1_CPU0_TEMP)
    plt.xlabel('Time')
    plt.ylabel('Node1 CPU0 Temp')

    final_path="plots/CD/"
    fig.savefig(final_path+filename+'_1.png')
    plt.close(fig)
    plt.show()
