Hello, I'm trying to calculate cumulative cost in my depth vs days and cost diagram. For example the cost should look something like that : Day_Cost Cumulative_Cost 150$ 150$ 150$ 300$ 200$ 500$ I'm trying to achieve this by using CHART PROPERTIES ->CHART DATA->CONFIGURATION AND MODIFY MY COST MEASURE. In the Cost measure I select calculation as a SUM and value expression as my day_cost, however, I'm not seeing any cumulative values. Is it possible to calculate cumulative value using my method or is it need to be calculated in MySQL query and if so, how would I do it without setting variables to store cumulative value. Here is a screenshot of my results, the red line shows linear progression that I want to achieve using cumulative costs. Any suggestions?
