I'm attempting to display a data chart which uses a negative minimum value and a range which crosses zero to it maximum value. 

X Min = -2000,  X Max = 1800, Range = -2000 to 18000

Y Min = 0, Y Max = 250 Y Range = 0 to 250

When displaying the chart fails to align the X and Y vertices at 0,0.  Is this possible? 

Note that for this data there are no X data values less than 0 but if there were I would expect them to appear before the Y axis.  

Here's my XAML:

Note that the dataplot and legends are rendered dynamically
