Data Calculation

[#1]

Good Day Community,

I would like to know how would i go about working out the difference between two days data eg. if 1/6/2013 = 200 and if  2/6/2013 =250 i would like to know how would i go about scripting, ( 250 - 200 = 50) as i require that value of 50.

Is it also possible to loop it so that it works out it out for the next dates and so fort?

Thank You Kindly

SR

It all depends on where do you want the result to be displayed.

• You can do it in the script
• You can do it in a chart/table (at the front end) - sort the table and use above()/below() functions

Hi Tres,

I would like to do it in a Table/Chart... could you possibly assist me with the code to go about working it out?

Hi,

Use Previous() function if you need to calculate previous record data.

Ex:

Load Date,

     Data,

Data-Previous(Data) as Difference;

Load Date, Data from [location of file];
