When using a DataTable, do I need to specify a value for every column in a row?

[Ramón]

I'm trying to create an area chart showing two series  One series is f1(x) for 0 < x < 10 and the other series is f2(x) for 0 < x < 5.  Maybe something like this for example....

x  f1  f2

1  0   0

2  0   3

3  0   5

4  3   3

5  5   

6  5

7  5  

8  5

9  3

Can I put both series in the same DataTable object if for series f2 the value for x > 5 is undefined or do I need to put in some value and then somehow suppress the visualization of that series beyond a certain point?  Is the question clear?

Yes, you can leave those values undefined and the chart will draw just fine.

Thanks, asgallant.  The problem was that I was not explicitly setting those elements to "undefined" and instead creating ragged arrays.  It works now.
