Smoothing data of the year

  1. Nov 8, 2013 #1
    Hi!
    I have a problem to resolve this question :

    I have a total value each month :
    January = 60
    Fébruary = 80
    March = 130
    April = 150
    May = 180
    June = 200
    July = 210
    August = 170
    September = 140
    October = 90
    November = 60
    December = 50

    I want to calculate the value each day of year, but the total of this values each month must be exactly like value previously describing.
    Also, the graphic render must be with smoothing line, like spline or simpson rule.

    See attached a excel base http://cjoint.com/?CKilaalz7z2

    How to make this ?!

    Thank you so much and have a nice day!

    Bye

    Simpson's rule is for numerical integration, so you don't want that.

    Any method is ok for me, the simply is the best because i must integrate this into PHP code after!
    Do you any idea?
    Thanks
