title: 3D Plotting from X, Y, Z Data, Excel or other Tools
body: <p>I have data that looks like this:</p>
  
  <pre><code>1000    13  75.2
  1000    21  79.21
  1000    29  80.02
  5000    29  87.9
  5000    37  88.54
  5000    45  88.56
  10000   29  90.11
  10000   37  90.79
  10000   45  90.87
  </code></pre>
  
  <p>I want to use the first column as x axis labels, the second column as y axis labels and the third column as the z values.  I want to display a surface in that manner.  What is the best way to do this?  I tried Excel but didn't really get anywhere.  Does anyone have any suggestions for a tool to do this?  Does anyone know how to do this in Excel?</p>
  
  <p>Thanks</p>
