Hello Forum.

I am using VISI Fire in Silverlight and C# to produce some data charts. One style of chart allows stacked data to be displayed in colums the xaml code I am using looks like this
[ I M G ] h t t p : / / i 6 7 . p h o t o b u c k e t . c o m / a l b u m s / h 2 9 2 / A t h o n o / x a m l . p n g [ / I M G ]

T h e c h a r t i am trying to build is based on a visi fire chart example. if you go to h t t p : / / w w w . v i s i f i r e . c o m / s i l v e r l i g h t _ w p f _ c h a r t s _ g a u g e s _ g a l l e r y . p h p a n d l o o k at their stacked examples here http://www.visifire.com/silverlight_stacke...rts_gallery.php you can see the xaml example I am trying to emulate.
h t t p : / / i 6 7 . p h o t o b u c k e t . c o m / a l b u m s / h 2 9 2 / A t h o n o / p o s t _ t h i s . p n g

But my chart comes out differently. mine has this odd overlaping date feature

[ I M G ] h t t p : / / i 6 7 . p h o t o b u c k e t . c o m / a l b u m s / h 2 9 2 / A t h o n o / b a d r e p r e s e n t a t i o n . p n g [ / I M G ]

N o w , I h a v e carefully stepped through the code and as far as I can tell, I have the same date for each data set pair.
[ I M G ] h t t p : / / i 6 7 . p h o t o b u c k e t . c o m / a l b u m s / h 2 9 2 / A t h o n o / c o d e - 1 . p n g [ / I M G ]

I h a v e stepped through this code and I have made sure that with each value for i, the years and the months for each data pair are exactly the same. So why is my graph so messed up?
