Seaborn在热图中显示3位数字的科学计数法 [英] Seaborn showing scientific notation in heatmap for 3-digit numbers

问题描述

我正在从pandasivot_table创建一个热图，如下所示:

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

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

它将创建一个热图，如下所示.您可以看到数字不是很大(最大为750)，但是以科学计数法显示了它们.如果我查看表格本身，则不是这种情况.关于如何使它以简单的符号显示数字有任何想法吗?

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?

推荐答案

根据

According to the docs, the param fmt=.2g is being applied because you've set annot=True so you can modify the format being applied to:

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