#!/usr/bin/env python # coding: utf-8 # # Convenience Methods for Exporting Plot to a File or File-Like Object # # You can export figure created by `ggplot()` or `gggrid()` functions
# to a vector or raster format using the following methods: # - `to_svg(path)` # - `to_html(path, iframe)` # - `to_png(path, scale)` # - `to_pdf(path, scale)` # # To save plot to a file on disc, specify the file' pathname in `path`.
# To stream plot image to a file-like object, supply such object in the `path` parameter instead of a pathname. # # In[1]: import numpy as np import io from IPython import display from lets_plot import * # In[2]: LetsPlot.setup_html() # In[3]: data = {'x': np.random.normal(size=100)} p = ggplot(data, aes(x='x')) + geom_histogram() # #### 1. Saving to a File # # In[4]: path = p.to_svg('lets-plot-images/hist.svg') # In[5]: display.SVG(path) # #### 2. Wrighting to a Stream of In-Memory Bytes # # In[6]: stream = io.BytesIO() p.to_svg(stream) # In[7]: display.SVG(stream.getvalue())
