Add Data to Dimension through InputField

[#1]

Hi Guys,

I have a scenario where i want to enter a date and  a value  that will be appended to a chart, eg

Scenario:

A Line chart with original data  Dimension-Year  (let say 2008-2009) and  Expression-Sum(Number), and now i want to

enter 2010 (as Year) and 10000 (as Number) in an InputField in a straight table(or something else), Then the Line chart can reflect the new input data.

The problem is that how we can input data to existing Dataset,  seems that the InputField  works only with InputSum/Avg and not Date,

Please help , Gurus.

Thanks in advance.
