ax.plot(alphas, coefs) ax.set_xscale('log') ax.set_xlim(ax.get_xlim()[::-1])

这段代码的作用是绘制一组系数与正则化参数之间的关系图，并将X轴设置为对数刻度。具体来说：

- `ax.plot(alphas, coefs)`：绘制系数与正则化参数之间的关系图。
- `ax.set_xscale('log')`：将X轴设置为对数刻度。
- `ax.set_xlim(ax.get_xlim()[::-1])`：翻转X轴的范围，使得刻度从大到小排列（因为对数刻度下，数值越小的点在X轴上越靠右）。

好的，你可以将这段代码修改为：

def draw_stats(self, vals, vals1, vals2, vals3, vals4, vals5, vals6, save_path):
        fig, axs = plt.subplots(4, 2, figsize=(16, 16))
        axs[0, 0].plot(vals)
        axs[0, 0].set_xlim(self.xlim)
        locs = axs[0, 0].get_xticks()
        locs[0] = self.xlim[0]
        locs[-1] = self.xlim[1]
        axs[0, 0].set_xticks(locs)
        axs[0, 0].use_sticky_edges = False
        axs[0, 0].set_title(f'Connected Clients Ratio')

        axs[1, 0].plot(vals1)
        axs[1, 0].set_xlim(self.xlim)
        axs[1, 0].set_xticks(locs)
        axs[1, 0].yaxis.set_major_formatter(FuncFormatter(format_bps))
        axs[1, 0].use_sticky_edges = False
        axs[1, 0].set_title('Total Bandwidth Usage')

        axs[2, 0].plot(vals2)
        axs[2, 0].set_xlim(self.xlim)
        axs[2, 0].set_xticks(locs)
        axs[2, 0].use_sticky_edges = False
        axs[2, 0].set_title('Bandwidth Usage Ratio in Slices (Averaged)')

        axs[3, 0].plot(vals3)
        axs[3, 0].set_xlim(self.xlim)
        axs[3, 0].set_xticks(locs)
        axs[3, 0].use_sticky_edges = False
        axs[3, 0].set_title('Client Count Ratio per Slice')

        axs[0, 1].plot(vals4)
        axs[0, 1].set_xlim(self.xlim)
        axs[0, 1].set_xticks(locs)
        axs[0, 1].use_sticky_edges = False
        axs[0, 1].set_title('Coverage Ratio')

        axs[1, 1].plot(vals5)
        axs[1, 1].set_xlim(self.xlim)
        axs[1, 1].set_xticks(locs)
        axs[1, 1].yaxis.set_major_formatter(FormatStrFormatter('%.3f'))
        axs[1, 1].use_sticky_edges = False
        axs[1, 1].set_title('Block ratio')

        axs[2, 1].plot(vals6)
        axs[2, 1].set_xlim(self.xlim)
        axs[2, 1].set_xticks(locs)
        axs[2, 1].yaxis.set_major_formatter(FormatStrFormatter('%.3f'))
        axs[2, 1].use_sticky_edges = False
        axs[2, 1].set_title('Handover ratio')

        plt.tight_layout()
        plt.savefig(save_path)
        plt.show()

这样就可以一张张输出图片了，你只需要传入一个保存路径参数 `save_path` 即可。

self.ax1 = plt.subplot(self.gs[0, 0]) 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') 单独输出

要单独输出这部分代码绘制的图形，可以使用 Matplotlib 库中的 pyplot 子库的 plot() 方法和相应的设置方法来创建和设置图形。例如，下面的代码将创建一个新的图形窗口，并在其中绘制一个线性图：

import matplotlib.pyplot as plt

# 创建新的图形窗口
fig = plt.figure()

# 绘制线性图
ax = fig.add_subplot(1, 1, 1)
ax.plot(vals)
ax.set_xlim(xlim)
locs = ax.get_xticks()
locs[0] = xlim[0]
locs[-1] = xlim[1]
ax.set_xticks(locs)
ax.use_sticky_edges = False
ax.set_title('Connected Clients Ratio')

# 显示图形
plt.show()

在这个例子中，代码创建了一个新的图形窗口，并使用 add_subplot() 方法创建一个 1x1 的子图，该子图被赋值给变量 ax。接下来，将 vals 序列传递给 plot() 方法来绘制线性图，并使用 set_xlim() 方法和 get_xticks() 方法来设置 x 轴的范围和刻度位置。然后，将 use_sticky_edges 属性设置为 False，这样就可以更好地控制图形的布局。最后，使用 set_title() 方法设置子图的标题。最后，使用 show() 方法显示整个图形。
