title: Re-plotting lines after clearing Axes3D
body: <p>I have a list to which I append Axes3D plots. Like this:</p>
  
  <pre><code>self.myList.append(self.axes.plot(xValues,
                                    yValues,
                                    zValues,
                                    picker=self.line_picker)[0])
  </code></pre>
  
  <p>When that line of code runs, the instance returned by the plot() function is stored in the list AND the line is automatically plotted, which is what I want. This code runs on program startup and draws a variable number of lines. </p>
  
  <p>Now what I need to do is this:</p>
  
  <p>When the user checks a checkbox, I want to REPLACE the data that is currently plotted with another set of data. Then, when the user unchecks the checkbox, I want the initial data to be plotted again. </p>
  
  <p>I have no problem with clearing the initial data; I simply do:</p>
  
  <pre><code>self.axes.clear()
  self.canvas.draw()
  self.axes.mouse_init()
  </code></pre>
  
  <p>and now I have a blank 3D graph. </p>
  
  <p>How can I re-plot the same data once it is cleared? Can I somehow use the plot instances stored in the list and re-plot them?</p>
  
  <p>My ultimate question is, do I have to re-plot the original plot using the raw data like I did the first time, or can I somehow hide/disable the initial axes and then simply restore it?</p>
