python ax.set_xlim

在Python中，`ax.set_xlim()`是用于设置图形的x轴范围的函数。它是Matplotlib库中Axes对象的一个方法，用于对当前图形的x轴范围进行设置。

`ax.set_xlim()`函数接受两个参数，分别是x轴的最小值和最大值。通过指定这两个参数，可以限制x轴的显示范围。

下面是一个示例代码，展示如何使用`ax.set_xlim()`函数来设置x轴范围：

import matplotlib.pyplot as plt

# 创建一个图形和一个子图
fig, ax = plt.subplots()

# 绘制一条曲线
x = [1, 2, 3, 4, 5]
y = [2, 4, 6, 8, 10]
ax.plot(x, y)

# 设置x轴范围为1到5
ax.set_xlim(1, 5)

# 显示图形
plt.show()

在上面的示例中，`ax.set_xlim(1, 5)`将x轴的范围限制在了1到5之间。这样，图形只会显示在这个范围内的数据点。

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。

python axes.set_xlim()

这个函数是用来设置坐标轴的x轴范围的。它需要两个参数，第一个参数是x轴范围的下限，第二个参数是x轴范围的上限。例如，如果想要将x轴范围设置为0到10，可以使用以下代码：

import matplotlib.pyplot as plt

fig, ax = plt.subplots()
ax.plot([1, 2, 3], [4, 5, 6])

ax.set_xlim(0, 10)
plt.show()

这会生成一张图，x轴范围为0到10，y轴范围根据数据自动调整。
