title: Excel - 3D interpolation
body: <p>I have to make a 3D graph in Excel. On the x-axis I want to make a linear distribution, but that doesn't work.</p>
  
  <p>Currently, it looks like this:</p>
  
  <p><img src="https://i.stack.imgur.com/3n2o5.jpg" alt="Graph"></p>
  
  <p>But , for example, the distance between 40-60 should be twice as large.</p>
  
  <p>Can you help how I should do this? I can't get interpolation to work in 3D graphs :(
  The .XLSX can be found <a href="https://dl.dropbox.com/u/3523511/OMNeT.xlsx" rel="nofollow noreferrer">here</a>.</p>
  
  <p>Thank you!</p>
