如何用 Python 将 Seaborn 剧情保存到文件中？
原文:https://www . geeksforgeeks . org/如何保存-seaborn-plot-to-a-file-in-python/
Seaborn 提供了一种以不同的期望文件格式存储最终输出的方式，如。巴布亚新几内亚。pdf，。tiff，。eps 等。让我们看看如何将输出图形保存为特定的文件格式。
逐步实施
第一步:
使用内置函数 load_dataset 从 seaborn 包导入内置的企鹅数据集。
语法:
seaborn.load_dataset(name, cache=True, data_home=None, **kws)
例:
Python 3
# code
# Install seaborn using pip install seaborn
# Import the seaborn package
import seaborn as sns
# load the inbuilt "penguins" dataset using
# seaborn inbuilt function load_dataset
data = sns.load_dataset("penguins")
# print the first 6 data
data.head()
输出:
第二步:
对于这个例子，让我们使用散点图来检查雄性和雌性企鹅的喙长 mm 和喙深 mm 之间是否有任何关系。
语法:
seaborn.scatterplot(x, y, hue, style, size, data, palette,
hue_order, legend)
第三步:
这是将绘图保存到所需文件类型的首要步骤。使用获取图形功能获取步骤 2 中绘制的图形。
语法:
figure_name.get_figure()
get_figure 函数将输出图形存储到变量中。将图暂时存储在变量中，如下所示
3a:将剧情另存为。巴布亚新几内亚:
最后，使用 savefig 功能并给出想要的名称和文件类型来存储该图。以下示例将绘图存储为当前工作目录中的. png 文件。
Python 3
# Install seaborn using pip install seaborn
# Import the seaborn package
import seaborn as sns
# load the inbuilt "penguins" dataset using
# seaborn inbuilt function load_dataset
data = sns.load_dataset("penguins")
scatter_plot = sns.scatterplot(
x=data['bill_length_mm'], y=data['bill_depth_mm'], hue=data['sex'])
# use get_figure function and store the plot i
# n a variable (scatter_fig)
scatter_fig = scatter_plot.get_figure()
# use savefig function to save the plot and give
# a desired name to the plot.
scatter_fig.savefig('scatterplot.png')
# this will store the plot in current working directory
输出:
3b:将海伯恩图形另存为。jpg
Python 3
# code
# Install seaborn using pip install seaborn
# Import the seaborn package
import seaborn as sns
# load the inbuilt "penguins" dataset using
# seaborn inbuilt function load_dataset
data = sns.load_dataset("penguins")
scatter_plot = sns.scatterplot(
x=data['bill_length_mm'], y=data['bill_depth_mm'], hue=data['sex'])
# use get_figure function and store the plot
# in a variable (scatter_fig)
scatter_fig = scatter_plot.get_figure()
# use savefig function to save the plot and give
# a desired name to the plot.
scatter_fig.savefig('scatterplot.jpg')
# this will store the plot in current working directory
输出:
3c:将海伯恩图形另存为。tiff
Python 3
# code
# Install seaborn using pip install seaborn
# Import the seaborn package
import seaborn as sns
# load the inbuilt "penguins" dataset using
# seaborn inbuilt function load_dataset
data = sns.load_dataset("penguins")
scatter_plot = sns.scatterplot(
x=data['bill_length_mm'], y=data['bill_depth_mm'], hue=data['sex'])
# use get_figure function and store the plot
# in a variable (scatter_fig)
scatter_fig = scatter_plot.get_figure()
# use savefig function to save the plot and give
# a desired name to the plot.
scatter_fig.savefig('scatterplot.tiff')
# this will store the plot in current working directory
输出:
第四步:
如果您希望将 seaborn 图保存到特定文件夹，请按照下面提到的步骤操作
Python 3
# Install seaborn using pip install seaborn
# Import the seaborn package
import seaborn as sns
# load the inbuilt "penguins" dataset using
# seaborn inbuilt function load_dataset
data = sns.load_dataset("penguins")
scatter_plot = sns.scatterplot(
x=data['bill_length_mm'], y=data['bill_depth_mm'], hue=data['sex'])
# use get_figure function and store the plot
# in a variable (scatter_fig)
scatter_fig = scatter_plot.get_figure()
# use savefig function to save the plot and give
# a desired name to the plot.
scatter_fig.savefig(r'C:\Users\Documents\test\Plots\scatterplot.png')
# this will store the plot in specified directory
