title: Excel plot time series frequency with continuous xaxis
body: <p>I want to plot a time series frequency data similar to the below. I tried many types of charts but they all put the time (ie 08:00) exactly under data series column, I also tried to type 8-9 , 9-10, 10-11 ...but that looks awful just because time series needs to be continuous. I want to have 8:00 and 18:00 as the starting and ending points and data series should come above intervals, between 8-9-10-11 etc.. Any suggestions?</p>
  
  <pre><code>08:00:00 - 09:00:00     12
  09:00:00 - 10:00:00     11
  10:00:00 - 11:00:00     13
  11:00:00 - 12:00:00     12
  </code></pre>
