要在Matplotlib 中更改图例的位置,可以使用plt.legend()函数。 例如,您可以使用以下语法将图例放置在绘图的左上角: plt.legend(loc='upper left') 默认位置是“最佳”——这是 Matplotlib 根据避免覆盖任何数据点的位置自动为图例找到的位置。 但是,您可以指定以下任何图例位置: 右上方 左上 左下方 右下 正确的 ...
However, the legend size is the default, which we would like to change. To alter the legend size, run the code below:sns.jointplot(df,x = "Age",y = "Weight", hue = "Sex") plt.legend(fontsize = "7") plt.show()As you will notice, we have significantly reduced the size of ...
