Python Seaborn 在热图中显示 3 位数字的科学记数法

Seaborn showing scientific notation in heatmap for 3-digit numbers

提问by cigrainger

I'm creating a heatmap from a pandas pivot_table as below:

我正在从熊猫数据透视表创建热图，如下所示：

table2 = pd.pivot_table(df,values='control',columns='Year',index='Region',aggfunc=np.sum)
sns.heatmap(table2,annot=True,cmap='Blues')

It creates a heat map as shown below. You can see the numbers are not huge (max 750), but it's showing them in scientific notation. If I view the table itself this is not the case. Any idea on how I could get it to show the numbers in plain notation?

它创建了一个热图，如下所示。您可以看到这些数字并不大（最多 750 个），但它以科学记数法显示它们。如果我查看表格本身，情况并非如此。关于如何让它以普通符号显示数字的任何想法？

According to the docs, the param fmt=.2gis being applied because you've set annot=Trueso you can modify the format being applied to:

根据docs，fmt=.2g正在应用参数是因为您已经设置，annot=True因此您可以修改应用于的格式：

sns.heatmap(table2,annot=True,cmap='Blues', fmt='g')
