Question

我有一个要绘制的数据框。

我正在使用以下代码：

def vizData3D(df, asg, dueDate):
    due_final = datetime.datetime.strptime(dueDate, "%Y-%m-%d")
    df['Time of Last Submission'] = pd.to_datetime(df['Time of Last Submission'], errors='coerce')
    start = due_final - datetime.timedelta(days=15)
    end = df['Time of Last Submission'].max() + datetime.timedelta(days=1)
    mask = (start < df['Time of Last Submission'])
    df = df.loc[mask]
    df.set_index('Student')
    df['Num Lines Last Attempt'] = df['Num Lines Last Attempt'].apply(pd.to_numeric)
    fig = plt.figure()
    ax = fig.add_subplot(111, projection='3d')
    x =  df['Num Lines Last Attempt']
    y = df['Time of Last Submission']
    z = df['Total attempts']
    #print(df[df['Num Lines Last Attempt'] < 0].count())
    ax.scatter(x, y, z, c='r', marker='o')
    ax.set_xlabel('X Label')
    ax.set_ylabel('Y Label')
    ax.set_zlabel('Z Label')

    plt.show()

当我尝试运行此程序时，出现错误：

ValueError: view limit minimum -0.05 is less than 1 and is an invalid Matplotlib date value. This often happens if you pass a non-datetime value to an axis that has datetime units

这没有任何意义。我在其他2D图中绘制了所有这些数据，并且它们起作用了。关于测试错误或修复方法的任何建议？有人对此有解决方案吗？
