UserWarning: Glyph 25910 (\N{CJK UNIFIED IDEOGRAPH-6536}) missing from current font. plt.show()

这个警告通常发生在使用 Matplotlib 绘制中文字符时，因为默认的字体可能不支持所有的中文字符。这个警告并不影响图像的生成，只是会导致一些字符无法正常显示。如果你想解决这个问题，可以尝试以下方法：

1. 更换字体：你可以使用支持中文的字体，比如 SimHei、SimSun、Microsoft YaHei 等。你可以通过以下代码更换字体：

import matplotlib.pyplot as plt
plt.rcParams['font.sans-serif'] = ['SimHei']  # 更换字体为中文支持的字体
plt.rcParams['axes.unicode_minus'] = False  # 解决负号'-'显示为方块的问题

2. 下载字体：如果你使用的字体还是无法支持某些中文字符，你可以下载包含这些字符的字体文件，并将其放到系统字体目录下。

3. 不显示中文：如果你不需要在图表中显示中文，你可以使用英文或其他语言的字符来代替中文字符。

希望这些方法能够帮助你解决问题。

这个警告是因为在你的代码中，使用了一些当前字体中没有包含的字符，导致这些字符无法正确显示。可以尝试更换字体或者忽略这个警告。如果你想忽略这个警告，可以在代码开头添加以下代码：

import warnings
warnings.filterwarnings("ignore", category=UserWarning)

这样就可以忽略这个警告了。但是，如果你想要正确显示这些字符，可以尝试更换字体。可以在代码中添加以下代码：

import matplotlib.pyplot as plt
import matplotlib.font_manager as fm

# 更换字体
myfont = fm.FontProperties(fname='C:\\Windows\\Fonts\\simsun.ttc')
plt.rcParams['font.family'] = ['sans-serif']
plt.rcParams['font.sans-serif'] = [myfont.get_name()]

# 画图
plt.plot(x, y)
plt.show()

这样就可以使用新的字体来显示图表中的字符了。

这是一些Matplotlib的警告信息。其中第一条警告表示，Matplotlib 3.6版本开始不再支持没有“required_interactive_framework”属性的FigureCanvases，这个属性用于指定绘图所需的交互式框架。如果你的代码中使用了这样的FigureCanvas，建议更新Matplotlib版本或修改代码以使用最新的FigureCanvas。

其他的警告则是指出当前字体中缺少一些中文字符，这可能会影响绘图结果的显示效果。可以通过更换字体或安装支持中文字符的字体来解决这个问题。

这些警告信息并不会影响代码的运行，只是提醒你可能需要注意一些绘图的细节问题。建议在代码中加入以下语句来禁止警告的输出：

import warnings

warnings.filterwarnings("ignore")
