    cumulative data in chart

      Hello,

       

      I have a table like this

       

      DateItemSale price
      2/11item 120
      2/11item 215
      3/11item 125
      4/11item 330

       

      I need to build a line chart with cumulative sales over time on it.

       

      I have a dimension of Date but how do I calculate a sum of sales up until that date in an expression?

       

      Thanks!!
