Help - Specific line chart needed

[#1]

Hi All,

I have a line chart dimensioned by

     - Time (Dates formated like 'MMM - YYYY'),

     - and a calculated dimension (3 categories based on price evolution)

          =If(aggr(avg(Price_Evolution), Part_Code)> dblPriceEvolBorne_Up, 'UP',

          If(aggr(avg(Price_Evolution), Part_Code)< dblPriceEvolBorne_Down, 'DOWN', 'STABLE'))

I want to compute a Quantity Index based on a spedific date.

So the chart will display 3 curves (related to the calculated dimension). Each curve will be equal to 100 at the specific date.

The expression I tried is the following :

          =   Sum(Gross_Quantities) /

          Sum({$ <Year_Months={'$(=Min(Implementation_Dates))'}>}

          Gross_Quantities)

The issue is that this limit the dimension of the chart to the date specify (only the Min(Implementation_Dates) appears with 3 points).

Please could you help me on this?

Many thanks in advance
