title: Excel line chart doesn't look right
body: <p>I need to create a line chart from some tabular data. The chart should show how weather (e.g. temperature) changes with time. But for some reason the result looks strange (I have attached a picture). Also, the chart displays hour part of the datetime as 0. </p>

  <p>Could you please help. Thanks.</p>
  
  <p>Addition: 
  The time is in format Date of type "3/14/01 13:30"</p>
  
  <p>I also tried a Scatter, and the result looks better, but datetime is weird, and it is missing hours:
