python - Seaborn 热图 : Customize A Label

Question

给出下面来自 here 的热图:

flights = sns.load_dataset("flights")
flights = flights.pivot("month", "year", "passengers")
ax = sns.heatmap(flights, annot=True, fmt="d")

for text in ax.texts:
    text.set_size(14)
    if text.get_text() == '118':
        text.set_size(18)
        text.set_weight('bold')
        text.set_style('italic')

如何将类似的逻辑应用于 y 轴刻度标签？例如，如果我想加强“February”，将其设为 13 号字体并将其涂成红色怎么办？

提前致谢!

几乎完全相同的想法，你只需要遍历yticklabels的列表:

flights = sns.load_dataset("flights")
flights = flights.pivot("month", "year", "passengers")
ax = sns.heatmap(flights, annot=True, fmt="d")

for label in ax.get_yticklabels():
    if label.get_text() == "February":
        label.set_size(13)
        label.set_weight("bold")
        label.set_color("red")
