解释 self.ax8 = plt.subplot(self.gs[3, 2]) row_labels = [ 'Initial number of clients', 'Average connected clients', 'Average bandwidth usage', 'Average load factor of slices', 'Average coverage ratio', 'Average block ratio', 'Average handover ratio', ] l, r = self.xlim cell_text = [ [f'{len(self.clients)}'], [f'{mean(vals[l:r]):.2f}'], [f'{format_bps(mean(vals1[l:r]), return_float=True)}'], [f'{mean(vals2[l:r]):.2f}'], [f'{mean(vals4[l:r]):.2f}'], [f'{mean(vals5[l:r]):.4f}'], [f'{mean(vals6[l:r]):.4f}'], ] self.ax8.axis('off') self.ax8.axis('tight') self.ax8.tick_params(axis='x', which='major', pad=15) self.ax8.table(cellText=cell_text, rowLabels=row_labels, colWidths=[0.35, 0.2], loc='center right') plt.tight_layout()

这段代码是用来生成一个展示模拟结果的表格，包括7行数据，分别是：初始客户端数量、平均连接客户端数量、平均带宽使用量、平均切片负载因子、平均覆盖率、平均阻塞率、平均切换率。表格中每一行数据都是由模拟得到的统计数据组成的。其中 `self.ax8` 是用来绘制图形的子图对象，`row_labels` 是表格中每一行的名称，`cell_text` 是表格中每一个单元格的数据，`colWidths` 是每一列的宽度，`loc` 是表格的位置。`plt.tight_layout()`是用来自动调整子图之间的间距，使它们更加紧凑。

抱歉，这段代码是用来绘制多张子图并将它们组合成一个大图的，不太适合只输出其中的一张子图。如果您只需要输出其中的一张子图，需要对代码进行相应修改，只绘制需要的子图并将其保存即可。例如，如果只需要输出第一行第一列的子图，可以将其余子图的代码注释掉，然后在最后加上保存图片的代码，比如：

def draw_stats(self, vals):
    self.ax1 = plt.subplot(1, 1, 1)
    self.ax1.plot(vals)
    self.ax1.set_xlim(self.xlim)
    locs = self.ax1.get_xticks()
    locs[0] = self.xlim[0]
    locs[-1] = self.xlim[1]
    self.ax1.set_xticks(locs)
    self.ax1.use_sticky_edges = False
    self.ax1.set_title(f'Connected Clients Ratio')

    plt.savefig('output.png', dpi=300)

这样，该函数将只绘制一个包含第一行第一列子图的图片，并将其保存为 'output.png' 文件。

(train_images, train_labels), (test_images, test_labels) = datasets.fashion_mnist.load_data() f = plt.figure(figsize=(12, 7)) f.suptitle('Label Counts for a Sample of Clients') client_data = collections.OrderedDict() for i in range(6): client_data[f'client_{i}'] = ( train_images[i*1000:(i+1)*1000], train_labels[i*1000:(i+1)*1000]) plot_data = collections.defaultdict(list) for example in client_data[f'client_{i}']: label = example[0].numpy() #images, labels = example[] #label = labels.numpy() plot_data[label].append(label) for i in range(6): plt.subplot(2, 3, i+1) plt.title('Client {}'.format(i)) for j in range(10): plt.hist( plot_data[j], density=False, bins=[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10])

这段代码使用了TensorFlow中的fashion_mnist数据集，将训练集和测试集分别赋值给了(train_images, train_labels)和(test_images,_labels)。接着，使用matplotlib库绘制一个12*7的图像，标题为“一组客户的标签计数”。然后用OrderedDict创建了一个名为client_data的字典，其中包含6个键值对，每个键值对表示一个客户的图片和标签。最后用defaultdict创建了一个名为plot_data的字典，用于收集每位客户的标签计数。
