title: display chart with if function in EXCEL
body: <p>I am currently creating a reporting chart for my company and i want to make it as easy as possible to set up this reporting. 
  Currently I am struggling with displaying charts in a nice way. My idea is that the user writes a 1 in say Cell A1, then a certain chart will show up at position A20, if he writes nothing it will not show. </p>
  
  <p>My idea  was something like </p>
  
  <pre><code>if(A1=1;Chart1;"") 
  </code></pre>
  
  <p>but unfortenatuly it does not work. Does anybody know a solution to this? </p>
  
  <p>Thanks in advance</p>
