[Matplotlib-users] pyplot.plot plotting points in wrong order making loops in the graph display

[vargfran <f.v...@ic...>]

Dear all
pyplot seems to be plottting(joining points with lines) in the wrong order I
have checked all the algorithms relating the data being plotted and
everything is in order
<http://matplotlib.1069221.n5.nabble.com/file/n42696/bad_line_joints.png> 
this can be observed in the image on how it makes these closed loops by
plotting a line between two points skipping one or several points in time
then going back to them before continuing to the next. I wonder if anyone
has encountered this problem before or knows a solution.

This looks like a problem in parsing date/time x values in a text input 
file, not a problem in the actual plotting.
