How to show Monthly YTD value having Month in horizontal bar of cross table

Hi,

I have a calculation(little complex as it is using many other custom measures) called "inflation" it is being calculated on the basis of "from" and "to" months selected in selection criteria. If I have selected Jan to March then inflation will get calculated using data from Jan to Mar and will be displayed as below:

What I want is to show inflation value on Monthly YTD basis.

So in Jan value should be calculated in Jan to Jan basis in Feb it should show Jan to Feb in March inflation should get calculated in Jan to Mar basis.

Meaning when month is put in tabular format then YTD month wise calculation should work.

Please suggest if it can be done through any filter or any custom measure is to be created.

Thanks,

Ankit
