0. Matrix Plots的繪圖種類

  • sns.heatmap

  • sns.clustermap

1. 使用library

import seaborn as sns

  • 將圖表直接嵌入到Notebook之中

%matplotlib inline

  • 讀入資料

tips = sns.load_dataset('tips')
tips.head()
flights = sns.load_dataset('flights')
flights.head()

2.heatmap (熱力圖)

  • 視覺化矩陣形式中各行列的數值關係

    • tc = tips.corr()
sns.heatmap(tc)

    • 視覺化歷史各年度中的各月份的航班密度

      # 重新排列資料
fp = flights.pivot_table(index='month', columns='year', values='passengers')
      sns.heatmap(fp)

    • 改變熱力圖的色調及線條

      sns.heatmap(fp, cmap='coolwarm', linecolor='blue', linewidth=1)

3.clustermap (階層式熱力圖)

sns.clustermap(fp)

  • 正規化

sns.clustermap(fp, cmap='coolwarm', standard_scale=1)

矩陣的視覺化
