这些警告是由于 Matplotlib 库使用的字体缺少一些特殊字符。你可以通过以下代码解决:
```python
import matplotlib.pyplot as plt
from matplotlib.font_manager import FontProperties
# 设置字体
font = FontProperties(fname=r"C:\Windows\Fonts\simhei.ttf", size=14)
# 在绘制图表前设置字体
plt.rcParams['font.family'] = ['SimHei']
# 绘制图表
plt.plot(x, y)
plt.show()
```
其中,`r"C:\Windows\Fonts\simhei.ttf"` 是指定字体文件的路径,这里使用的是黑体。如果需要使用其他字体,可以替换为相应的字体文件路径。

这是一个UnicodeDecodeError错误,意味着Python无法使用UTF-8编码正确解码文件。可能是因为文件编码与Python默认编码不同,或者文件本身出现了无法解码的字符。
你可以尝试指定文件编码来解决此问题。例如,如果文件编码为GB2312,可以使用以下代码读取文件:
```python
import pandas as pd
data = pd.read_csv('车辆:1499序:2结果数据换算单位.csv', encoding='GB2312')
```
如果指定了正确的编码仍然无法解决问题,那么文件内容可能存在其他问题,需要进一步检查和处理。

这是一个警告信息,提示你的字体库中缺少一些字符,可能会导致图形显示不完全或乱码。你可以通过更改字体或安装缺失的字体来解决这个问题。同时,还有一个关于 FigureCanvas 的警告,这意味着 Matplotlib 将不再支持没有 required_interactive_framework 属性的 FigureCanvas,在未来的版本中可能会被删除。
