要可视化这两个列表，可以使用matplotlib创建一个水平条形图。每个段将表示为彩色条，其中颜色指示类别标签。下面是一个示例代码来实现这一点：

import matplotlib.pyplot as plt

# Given lists
GroundTruth_List = ['sit', 'sit', 'sit', 'order_coco', 'order_coco', 'drink_coco']
Predicted_List = ['sit', 'sit', 'sit', 'order_coco', 'order_coco', 'drink_milk']

# Prepare data for plotting
labels = set(GroundTruth_List + Predicted_List)
label_colors = plt.cm.tab20.colors[:len(labels)]  # Get a set of distinct colors

# Function to plot a segment as a colored bar
def plot_segment(start, end, label, color):
    plt.barh(0, end - start, left=start, height=0.5, color=color, alpha=0.7, label=label)

# Plot the GroundTruth_List
for i in range(len(GroundTruth_List)):
    start = i
    end = i + 1
    label = GroundTruth_List[i]
    color = label_colors[list(labels).index(label)]
    plot_segment(start, end, label, color)

# Plot the Predicted_List
for i in range(len(Predicted_List)):
    start = i
    end = i + 1
    label = Predicted_List[i]
    color = label_colors[list(labels).index(label)]
    plot_segment(start, end, label, color)

# Add legend and labels
plt.legend(loc='upper right')
plt.yticks([])
plt.xlabel('Time (seconds)')
plt.title('Sequence Segmentation Visualization')

plt.show()
