    QlikSense null trend line

    Michele De Nardi

      Good Afternoon,

      i'm trying to add a trend line to my combo chart by usign the formula mentioned in How to add lineal trend in Qlik sense thread.

       

      The base formula is this:

       

      linest_m(total aggr(if(sum(Sales),sum(Sales)),OrderDate),OrderDate)*  
      only({1}OrderDate)+linest_b(total aggr(if(sum(Sales),sum(Sales)),OrderDate),OrderDate) 
      

       

      so i replace with my measure and dimension to obtain the trend line.

       

      linest_m(total aggr(if(sum(Orders),sum(Orders)),Period),Period)*  
      only({1}Period)+linest_b(total aggr(if(sum(Orders),sum(Orders)),Period),Period)
      

       

      But i don't know why it returns null()...

       

      Can anybody help me ? I've attached the example qvf.
