plt.rcParams['axes.labelsize'] = 14

As an AI language model, I cannot generate a plot. However, I can explain the effect of the above code on a plot.
The above code changes the default font size for the labels of the axes in a Matplotlib plot to 14 points. This means that the x-axis label, y-axis label, and any other labels on the plot will be displayed in a font size of 14 points. This can improve the readability of the plot, especially if the default font size is too small for the audience or the plot is displayed in a small size.

cbar.ax.tick_params(labelsize=10)
`cbar.ax.tick_params(labelsize=10)` 是Matplotlib库中用于调整颜色条(Color Bar)轴标签字体大小的一个函数。在创建颜色条时,如果你想要改变其刻度标签的文字大小为10像素,可以在生成颜色条之后调用这个方法。它会修改color bar轴上所有刻度标签的字体大小,使其统一为指定的值,这对于提高图表的可读性很有帮助。
例如,在绘制热力图(heatmap)或者其他需要添加颜色条的图像时,你可能会这样做:
```python
import matplotlib.pyplot as plt
import numpy as np
data = np.random.rand(10, 10)
fig, ax = plt.subplots()
im = ax.imshow(data)
# 创建并显示颜色条
cax = fig.add_axes([0.9, 0.1, 0.03, 0.8])
cbar = fig.colorbar(im, cax=cax)
# 调整颜色条轴的标签大小
cbar.ax.tick_params(labelsize=10)
plt.show()
```
plt.rcParams
plt.rcParams是matplotlib库中的一个模块,用于在绘图时设置参数和默认值。通过修改plt.rcParams中的参数,可以改变绘图的样式、字体、颜色、线条粗细等各种属性,从而定制化自己的图形。
常见的plt.rcParams参数包括:
- 'figure.figsize':图形的大小,以英寸为单位,默认为(6, 4)。
- 'figure.dpi':图形的分辨率,每英寸点数,默认为100。
- 'font.family':字体类型,默认为'sans-serif'。
- 'font.size':字体大小,默认为10。
- 'lines.linewidth':线条宽度,默认为1.5。
- 'axes.grid':是否显示网格线,默认为False。
- 'axes.facecolor':坐标轴背景颜色,默认为'white'。
- 'xtick.labelsize'和'ytick.labelsize':坐标轴刻度标签的字体大小,默认为10。
通过修改这些参数,可以让绘制的图形更加美观、易读。例如,可以将字体设置为更大的Arial字体,线条粗细设置为2,背景颜色设置为灰色:
``` python
import matplotlib.pyplot as plt
plt.rcParams['font.family'] = 'Arial'
plt.rcParams['font.size'] = 16
plt.rcParams['lines.linewidth'] = 2
plt.rcParams['axes.facecolor'] = '#F0F0F0'
```
这样,在绘制图形时,就会自动使用这些参数进行设置。
