title: Using pptx without having to first save outputs to jpg files
body: <p>I am creating a powerpoint in Python, where the slides are the output graphs from the Jupyter Notebook cells.</p>
  
  <p>I am able to do this, but only if I save each output as a jpg. For example, see the code below:</p>
  
  <pre><code>data = pd.read_csv("123.csv")
  data.columns = ['Color Group', 'BASE VOLUME']
  x= data['BASE VOLUME']
  y= data['Color Group']
  
  data2 = data
  data2['BASE VOLUME %'] = data2['BASE VOLUME']
  data2 = data2.iloc[:,[0,2]]
  data2['BASE VOLUME %'] = 100*data2['BASE VOLUME %']/(sum(data2['BASE VOLUME %']))
  data2['Type'] = 'Total'
  total = data2.copy()
  
  plt.figure(figsize=(10,6))
  
  clrs = ['deepskyblue' if (x &gt; 10) else 'gray' for x in data2['BASE VOLUME %']]
  ax = sns.barplot(x,y, data=data2, palette=clrs)
  ax.set_xlabel('Base Volume',fontsize=15)
  ax.set_ylabel('Color Group',fontsize=15)
  plt.xticks(fontsize=15)
  plt.yticks(fontsize=15)
  
  for i, v in enumerate(data2['BASE VOLUME %']):
      ax.text(0 + 0.01*max(data['BASE VOLUME']), i + len(data2)/50, str("{0:.1f}%".format(v)), color='black', fontweight='bold', fontsize=14)
  
  plt.title('Total'.format(s),fontsize=15)
  
  plt.savefig("Total.jpg",bbox_inches='tight')
  
  #Create Powerpoint
  from pptx import Presentation
  from pptx.util import Inches,Pt
  
  prs = Presentation('input.pptx')
  blank_slide_layout = prs.slide_layouts[1]
  
  img1 = 'Total.jpg'
  slide = prs.slides.add_slide(blank_slide_layout)
  pic = slide.shapes.add_picture(img1, Inches(0.55), Inches(2), height=Inches(4.8), width=Inches(8.8))
  title = slide.shapes.title
  title.text_frame.paragraphs[0].font.size=Pt(50)
  title.text = "Total"
  </code></pre>
  
  <p>Is there a way of creating a similar line to<code>plt.savefig("Total.jpg",bbox_inches='tight')</code>, without saving a file - i.e calling the plot "something (say x)" that can be called back at any point? Then later I can replace the line <code>img1 = 'Total.jpg'</code> with <code>img1 = x</code> etc. </p>
