title: MatPlotLib Scatterplot removal
body: <p>I am trying to remove some data plotted as a scatter plot on matplotlib in python. I plot some scatter data and some 'plot' line data</p>
  
  <p>To remove the 'plot' line data I use : <code>del self.plot1.lines[0]</code></p>
  
  <p>What is the equivalent command to remove a <strong>scatter plot</strong>? I cannot seem to find it.</p>
