要在 Jupyter Notebook 中创建热力图,需要使用 Python 的 Matplotlib 数据可视化库和 Seaborn 统计数据可视化库。以下是创建热力图的基本步骤:
1. 导入库:导入 Matplotlib 和 Seaborn 库。
```python
import matplotlib.pyplot as plt
import seaborn as sns
```
2. 准备数据:准备包含行、列和值的数据表。数据表应该是一个矩阵,行和列应该具有相同的长度,值应该是数值型的。
```python
import pandas as pd
data = pd.read_csv('data.csv')
```
3. 创建热力图:使用 Seaborn 库中的 `heatmap()` 函数创建热力图。在函数中,需要传递数据表、行标签、列标签和调色板等参数。
```python
sns.heatmap(data, xticklabels=True, yticklabels=True, cmap='coolwarm')
plt.show()
```
4. 显示热力图:使用 Matplotlib 库中的 `show()` 函数显示热力图。
完整代码如下:
```python
import matplotlib.pyplot as plt
import seaborn as sns
import pandas as pd
data = pd.read_csv('data.csv')
sns.heatmap(data, xticklabels=True, yticklabels=True, cmap='coolwarm')
plt.show()
```
请注意,以上代码仅为示例,您需要根据实际情况调整参数和数据表。
