2.热力图 sns.heatmap 调整 图内，坐标轴，color bar 字体大小

热力图 sns.heatmap 调整 图内，坐标轴，color bar 字体大小_sns.heatmap字体大小_kev_gogo的博客-CSDN博客原始首先准备一个文件，我用的是csv文件我们先看一下最原始的效果：代码为：student = pd.read_csv('./input/small_data.csv')plt.figure(figsize=(25, 10))sns.heatmap(student.corr(), annot=True, cmap='YlGnBu')plt.savefig('relevance.png')plt.show()可以看到每个字都很小，那么接下来开始我们的调整坐标轴调整坐标轴，我们只需要在h_sns.heatmap字体大小https://blog.csdn.net/weixin_45415929/article/details/124018815?spm=1001.2101.3001.6650.2&utm_medium=distribute.pc_relevant.none-task-blog-2%7Edefault%7ECTRLIST%7ERate-2-124018815-blog-79132602.235%5Ev38%5Epc_relevant_default_base&depth_1-utm_source=distribute.pc_relevant.none-task-blog-2%7Edefault%7ECTRLIST%7ERate-2-124018815-blog-79132602.235%5Ev38%5Epc_relevant_default_base&utm_relevant_index=5

3.坐标轴和标签放顶上

标签

ax.set_xlabel('X LABEL')    
ax.xaxis.set_label_position('top') 

坐标轴

ax.xaxis.set_ticks_position("top")
ax.xaxis.tick_top()

4.cbar水平横放

plt.figure(dpi=120)
sns.heatmap(data=df,
            cmap=palettable.cartocolors.diverging.ArmyRose_7.mpl_colors,
            cbar=True,
            cbar_kws={'label': 'ColorbarName', #color bar的名称
                           'orientation': 'horizontal',#color bar的方向设置，默认为'vertical'，可水平显示'horizontal'
                           "ticks":np.arange(4.5,8,0.5),#color bar中刻度值范围和间隔
                           "format":"%.3f",#格式化输出color bar中刻度值
                           "pad":0.15,#color bar与热图之间距离，距离变大热图会被压缩
                                                   },
            
           )
plt.title("图例位置、名称、标签等设置：cbar_kws")
