One of our govt. agencies requires that I compute the 24-month rolling averages of the daily average input to a manufacturing process. In this instance, the agency is demanding the rolling average since 2003, so there are a fair number of data points involved. The process control computer can provide me the daily data (attached file contains 30 months of data), but cannot compute the 24-month rolling average.

Alas I need to put more dynamics and fill this data set from other sheets, so I'm putting formula into column A, and this force chart react and insert another category.

In other words I want to have this fill only if data present on different tab(worksheet).

That what I have now:

[Code] ........

COUNTA

Counts the number of cells that are not empty and the values within the list of arguments. Use COUNTA to count the number of cells that contain data in a range or array.

See Attached.

The YTD 10 column is fine that will change everytime you update each month. I was wondering if there was a formula I could use for the Rolling 12 month Column.

At the moment it is averging from Mar 09-Feb10 which is correct but when it comes to putting in data for Mar 10, the Rolling 12 month column will obviously not change.

Is there a way of moving the formula along one each time you input data into a new month. So when Mar 10 has been entered the rolling 12 month column will pick up Apr-09-Mar-10 then when Apr 10 has been entered the formula will change again to May-09-APr-10?

I have researched and read multiple threads related to graphing rolling averages per month. I've setup my own but I cannot get it to graph correctly. The x axis will be the days of the month ie. 1-31. The y axis is obviously the sales volume. The legend should be a line graph for each individual month sales. I want the graph to reflect the current month and previous 12 full months.

I used the file user rockycj started for another user in a different thread labeled, "Excel Line Chart - 12 month chart moving with dates ". It was very helpful and I'm trying to get this completed before my deadline. If anybody could take a look and let me know, I would greatly appreciate the help. I have attached the file for reference.

In a worksheet, I have the following columns:

A: Name

B: Absence Type

D: Date

F: Event

"A" is the employee name. "B" explains the type of absence, (SICK, LATE, UNAUTHORISED, UNPLANNED). "F" states if the absence is the first date of the instance (TRUE) or a subsequent day of the same instance (FALSE).

In order to effectively monitor absence levels, I'm looking to calculate a rolling % of each absence type.

I will require a column "L" that tallies the number of total number of "TRUE" instances for each absence type, per person, within the last 12 months. A column "M" that tallies the total number of instances of an absence type, per person, within the last 12 months. And finally, based on column "M", the % of that absence type within the last 12 months.

Regarding that final column, I have been advised that to obtain this value the basis of the calculation would be "(Number of Instances / 220) * 100". I have been told 220 represents the approximate number of days an employee should work over a twelve month period, but I am dubious about the accuracy of this calculation and any alterntives.

I've been working on this for a couple hours and I am close to getting it how I want. Basically I want to have a rolling 15 month graph that will change according to the month you choose in the drop down tab. Example: I choose july 2007, the graph will show data from july 2007 to September 2008. I have the graph functioning, however my formulas are off (collecting the wrong data). I've included a spread sheet

Trying to set up a 12 month rolling sum. However, the only issue with it is that there a re future date cells already in place (august through December of this year). Is there a way to have a formula automatically ignore these by using todays date or something? That was the person using the workbook doesn't have to delete these columns and re-add in the future?

I have a spreadsheet that ranks the 500 components of the S&p 500 on an ongoing intraday basis. I would like to have the sheet sorted automatically as it is updated. I have very limited VB skills. Also, I heard there is a feature on excel 2007 that performs this function.

I have a sales level that I need to track...My rolling 12 months' sales must be $85,000 and my currently monthly sales must be $7,000. I have a sheet that tracks the $85,000 and tells me what I need to achieve that, but I haven't figured out how to include the $7,000 monthly minimum....

The chart below is what I have. So for example, this month it's telling me I only need to sell another 3016.46 to hit the $85,000 rolling 12, but I actually need to hit $4821.79 to meet the $7k minimum.

I have a drop down list in cell F1 with all the months. In G1, I would like it to automatically display the number of days in the selected month. Of course it depends on the current year (due to leap year, etc).

I need a function/macro that will find all rows that have a specified value in column A and extract selected columns to a new spreadsheet. More, I need it to do it for every value in column A.

I would also like it to skip creation of new worksheet if value in selected row and column is null.*

I've been trying to combat this problem with advanced filters, which helped, but due to size of the data and range of values in column A it takes an entire day to process manually. Because the data is exported to another program after it's processed, it can't stay in the same sheet, also, linking back to the original sheet doesn't work because the data changes all the time.

I would like to ask for some assistance to my Spreadsheet problem.

To illustrate my problem please see below:

1------------> Level 1

1.1----------> Level 1 Sublevel 1

1.1.1--------> Level 1 Sublevel 1 Item 1

1.1.2--------> Level 1 Sublevel 1 Item 2

1.2----------> Level 1 Sublevel 2

1.2.1--------> Level 1 Sublevel 2 Item 1

1.2.2

2

2.1

2.1.1

2.1.1

2.2

and so on

I need to have a formula to automate the adding of outline numbers from "Level 1, Sublevel 1, Item 1..." So that if I deleted or added a row, the rest will automatically update themselves.

I will be the one manually inputing the Top Level and Sublevels I just need that the Items will be automatically added and computed basing from the previous level.

What I am planning to do is:

1. Check previous cell if the format has two decimal points or periods --> kinda stuck here

2. If there's only one then it will be the Sublevel 1 Item 1 (or depending to its location)

3. If there's already two periods "." then it will compute automatically for what item it is already.

ie:

1

1.1

1.1.1

1.1.2----->Checks the previous cell if it has 2 decimal places then if it does then it will add 1

I have a workbook with so many sheets as the working days of a month. I also have a Master sheet.

The sheets are named as the dates. Example: 020113 , 020113, 030113......etc

In the Master sheet, first column has ALL working dates of the month(i don't care about Holidays).

First row of this sheet are headers.

My goal is from the sheet of the certain date of the month automatic copied certain cells values(same in eatch sheet) to certain cells in Master Sheet.

I want to create a monthly timesheet which contains 9 columns for

(Date, Day, Project no., Activity, Time In, Time Out, Total Hours, OT Hours, Remarks)

I have used IF Function to calculate Total Hours & OT hours automatically. Time IN & Time OUT, Project No., will be entered manually on daily basis.

Weekday function is used in the Day column to return the corresponding day of the date in the Date column.

Name of the Month and Year will be manually entered in the designated cells I3 and I4 respectively.

Now the solution I am looking for is, the dates should be automatically entered in the Date column (in cells A8 to A38) based on the Month & Year entered in cells I3 & I4. Dates of the corresponding month of the year should only be filled in. (If a month is not having 29, 30 or 31st day, the corresponding cells should be left blank. i.e. nothing should be displayed in the corresponding cells). I am looking for some sort of formula to enter in the cells of Date column (A8 to A38) achieve this. I have searched the forum and could not find anything which could at least give me an idea about the kind of function or formula to be used.

Attached here is the time sheet I am trying to create.

I am trying to write a macro but I got a little stuck. Basically on row 6 I have the months listed out (so like Jan Feb Mar etc), and i would like my macro to dynamically search the the cell of current month and select it.

I know the cell formula for current month (ie. "Mar") is =TEXT(TODAY(),"MMM"), but is there a way to incorporate it into a search command in macro, or do I have to insert the formula into another cell and ask the search function to search for the text value in such "dummy cell"?

Another thing to note is, I do have more of "Mar"s scattered around the sheet, but if I limit my search area to row 6 there is only one, and that's the one I need to select.

I have a list of dates going through several years of data - month ends and starts don't always coincide with calendar months. I need to figure out a way to get the oldest date of the previous month, for example. Tried vlookup but could figure out how to do it for one year only, hence not as applicable with several years of data.

I m trying to write a formula for my financial model. If anyone can take a stab at a solution. I'm trying to write a formula that will equally distribute revenue either over the next 1 month, 2 month or 3 month period depending on size of the deal.

Details:

Sales will fit in 1 of 3 categories. Less than 25k; between 25k & 100k; greater than 100k.

- if under $25K, recognize in next month (month N+ 1)

- $25K-100K, recognize in two equal parts in months N + 1 and N + 2

- over $100K, recognize in three equal parts over 3 months

N + 1, N + 2, N + 3 ...

I have a spreadsheet which has data in the format of:

Date

Sales

Monday, 8 July 2013

191

Tuesday, 9 July 2013

180

[Code] ....

I calculate the average of the last four weekdays individually with =Average(A1,A8,A14..) in a cell above them to get a four week average.

Each time I add a new weeks worth of data, I manually adjust the formula to remove the first cell, and include the latest cell with new data.

I'm looking to find out if there is a way I can automate adjusting the formula so it always grabs the last four Mondays (for example)? Either in VBA or a formula.

I am working on a spread sheet and am trying to use rolling averages of the last 3 months. I am using worksheets for each month with a final worksheet containing the 3 mo. rolling average. I tried using a formula with OFFSET and it worked fine if all the data was in 1 worksheet, but did not work for multiple worksheets averaging to another worksheet in the same workbook.

Is there a way to make a VBA code where everytime I run this macro it adds 1 to a cell and keeps a running total?

Example:

E17 currently = 0

Running the macro makes it display 1

Running it again makes it display 2 etc...

I have a column of data (Column A) and I'd like to build first the Average of the first 20 data points (like in an Excel spreadsheet, cell B21 will contain the average(A2:A21), cell B22 will contain average(A3:A22), and so on... rolling).

I looked up on the internet, but I simply don't know how to start with, I mean, how to name the new array and make it rolling.

Then I will need to calculate STDEV for the same interval, and then Zscore ((Value - Average)/STDEV), but I guess it comes automatic once you made the first part.

I'm looking for some help to create a rolling 12 mth average. To explain better I have added a copy of the part of the sheet to help you understand what I am working with.

What I'm looking for is the 12 mth average to show up in cell c26. I have the mths listed in cell A2-A25 and the data I want averaged is in C2-C25

An additional problems is that I only want the 12 mth avg calculated if data in the next mth is greater than zero. Meaning since this month is Mar-09 (which is already collecting data) I dont want to include Mar-09 data yet. I only want to know Mar-08 to Feb-09 average. Once data is returned to Apr-09 then I want the average to show for Apr-08 to Mar-09 and so on. I dont what is better to use vba code or a formula which ever is easier.

Or if someone has a better idea please share.

I need a formula to give me a ROLLING SUM of the last 12 entries in a column, to give a rolling year sum.

Each month a new number would be added to the column at the end just before the rolling sum calculation.

The formula then would sum the new entry plus the preceding 11 entries.

E.g. Cell values as follows: A1=10, A2=6, A3=3, A4=9, A5=4, A6=5, A7=13, A8=2, A9=7, A10=1, A11=14, A12=5

Say the sum is in cell A13, the sum=79.

A row is inserted above A13 and 7 is entered.

Now the sum calculation is in cell A14 and the calculation is from A2:A13 which equals 76.

I have an excel sheet setup with several tabs which are organized by work days in a week. (i.e. aug 18, aug 19, aug 20, aug 21, aug22, aug 25, aug 26, aug 27, aug 28, aug 29) Sample file has been included.

I would like to do a rolling total of 1 particular cell (the same location on all the sheets, i.e. cell a2 on all sheets) for the past 4 weeks, and it automatically adjusts itself based on today's date (i.e. today is august 27, it will total everything from jul 30, 31, aug 1, 4, 5, 6, 7, 8, 11, 12, 13, 14, 15, 18, 19, 20, 21, 22, 25, 26.).

Is it possible to do this?

I am not familiar with VBA or Macros, so solutions using either of these will require some detailed explanation for me to understand how to apply them.

I have several worksheets with thousands rows (independent variables) and hundreds columns (all dependent variables). Each line basically gives me hundreds values for each independent variable - see below:

...

E9 7535.92 21500.56 2835.88 3122.98 7225.34 5371.25 ... ...

G9 111568 298021 12940 31645 181797 36996 ... ....

...

I need to know how the values in each row are distributed, and I ideally plot a 2D column graph of the distribution. Is there a way to do that and create/program a macro (with relative button on the workboook) that does it automatically once clicked?

Very often there are outlying values (bigger or smaller by a factor of 1000 or even more), mistakes, which I would like to identify and fix possibly

Whenever I add new data I need two cells of the old data to not be counted. This should continue until old data isn’t being counted anymore.

EXAMPLE:

New Data entered Cell C36:E36 (148, 147, 214)

Old data shouldn’t be counted anymore from Cell C67:E68 (137, 152, 156, 94, 117, 158)

Total before New data Entered: 14066

After New data Entered: 13761

This formula is required for a total of 16 weeks or until all the old data isn't being calculated anymore in my rolling total.

I only need one total the three examples are just showing what the total should be calculated.
