I have a fairly simple Line chart that displays the results of backgammon sessions, where each data point is the cumulative total of points won/lost over time when I sort by Session Date.  Works fine.

 

Displaying the Dates along the bottom is not useful, but what *would* be useful would be to see demarcations where the *Year* changes.  I know how I would  display just the year for each session data point . . . but is there a way that I could display just the major demarcations where a new Year *begins*?

 

2008              2009                                             2010             2011

 

. . . they would not be evenly spaced, since there are more sessions in some years than others.

 

 

Reflecting on this, I'm thinking perhaps I could define a new Calc field that would display the Year only if the Session's Date is the first date in a given year?  But I'd also need to limit the calc to the current Found Set . . . 

 

Any pointers on how to take this approach?
