Excel 2007 : Plotting two time data series

Hi! A strange thing is happening when I attempt to plot two axis on the same plot, with date and time on the horizontal axis. Cannot figure out what I'm doing wrong. I just select All tha data and insert 2-D charts (have tested all of them). Anyone who have an idea what I'm doing wrong. I fihure the image will show the problem.ExelSpm.JPG

Next time please upload a file
Hope this helps
Best regards
