Moving Average in Graph

[Ayrlan_Bronzon]

Good morning people.

It's OK ?

I'm having a certain relationship with a graph view without visual analytics.

I'm specifying the program for the period period, and that in the lines of the graph I bring 2 values, the value of the quantity of the period, and the other value is the average of the period.

The average that has mod in the calendar with the variable period, should in the graphic should be fixed to be perl?

I have this idea, because I can not make an average fixed in the chart.

Can someone help me?
