plt.figure(figsize=(8,4),dpi=100)

As an AI language model, I do not have the capability to display visualizations. However, I can explain that the code "plt.figure(figsize=(8,4),dpi=100)" is used in Python to create a new figure with a specific size and resolution.

- "figsize=(8,4)" sets the width and height of the figure to 8 and 4 inches, respectively.
- "dpi=100" sets the resolution of the figure to 100 dots per inch.

This code is often used in conjunction with other plotting functions in the Matplotlib library to create customized and high-quality visualizations.

p1 = plt.figure(figsize=(10,10),dpi=80)

As an AI language model, I cannot generate a plot. However, I can explain the code for you.

The code `p1 = plt.figure(figsize=(10,10),dpi=80)` creates a new Figure object with a size of 10 inches by 10 inches and a resolution of 80 dots per inch (dpi). The `plt` module is from the matplotlib library, which is a popular data visualization library in Python. The `figure()` function creates a new figure object, which is like a blank canvas where you can add plots, images, and other visual elements. The `figsize` argument sets the width and height of the figure in inches, while the `dpi` argument sets the resolution or sharpness of the figure.

You can then add plots or other visual elements to this figure using other matplotlib functions, such as `plot()`, `scatter()`, `imshow()`, etc.

plt.figure(figsize=(90,20),facecolor='b',dpi=500) 这个代码放在哪里合适

`plt.figure(figsize=(90,20), facecolor='b', dpi=500)` 是 Matplotlib 中用于创建一个新的图形窗口的命令，其中 `figure()` 函数是用来创建新的图形，而其他参数如 `figsize`、`facecolor` 和 `dpi` 分别设置图形的尺寸、背景颜色和分辨率。

这段代码应该放在你开始绘制图形的地方，通常是你的主程序或脚本的主体部分，例如在数据分析或可视化流程中。具体来说，它可能会出现在 `matplotlib.pyplot` 库导入后，你准备开始创建第一个图表之前：

import matplotlib.pyplot as plt

# 创建新图形并设置参数
plt.figure(figsize=(90, 20), facecolor='b', dpi=500)

# 然后在这里添加你的绘图代码，如：
x = [1, 2, 3]
y = [4, 5, 6]
plt.plot(x, y)
# ...更多绘图操作...

# 最后展示或保存图像
plt.show() 或 plt.savefig('my_plot.png')
