Creating Frequency Distribution Chart From Large Dataset - VBA?
Dec 16, 2013
I have a table that can at any point have from a couple hundred up to a couple thousand rows. Within this table lies a column entitled " Offer ". I want to plot the figures in the offer column as a frequency distribution chart.
I plan to do this by listing the x-values (Offer figures), and then using count if formulas to calculate the frequency of that x-value. Then using a simple clustsered column chart to create the visualisation of the frequency distribution.
My question is.... in my large data set, is there any way to get VBA to insert a list of the range of figures in the Offer Column, ? I can figure out how to copy down the countif formula to populate the corresponding frequency column, but how can I have some VBA to dynamically adjust my x-values (offer figures)?
For example... say in the first data set I have
Offer, Frequency
1 10
2 20
3 25
4 20
5 15
that's fine if I make the chart, but what if the data set changes, I want VBA to give me a list of all the offer values, and then I can write some code to insert and copy down along the frequency column the countif formula.
The ultimate goal is to have a frequency chart that will be synced to the self-updating dataset.

We collect loan payments for 36 months from customers.
Column A lists 1000+ customers.
Column J lists the date we received payment 1 ... Column Q lists the amount we received on payment 1.
Column R lists the date we received payment 2 ... Column Y lists the amount we received on payment 2.
Column Z lists the date we received payment 3 ... Column AG lists the amount we received on payment 3.
This repeats for all 36 payments.
New customers are loaded in each month, so be aware that Column J, Column R, Column Z (and so on) have dates from 2011 and 2012 and 2013.
We'd like to create a list of all customers that have not made a payment for the current month as of a certain day (say the 12th). So this month, on January 12th, we'd like to search our data for all customers that don't have a payment listed between January 1st - January 12th.

I'm working on has me making a frequency distribution of the yields column. If you look at M6 on the spreadsheet i'm trying to use the formula:
=COUNTIF($I$6:$I$35, "<=L6")
to represent all yields that are less than or equal to 0, in the next box (M7) I want to represent all yields that are greater than 0% and less than or equal to 1%. etc until I reach 7%, however the original formula isn't working and I don't know whats wrong with it.

I want to randomly select letters from this distribution (to make random words) but I want the more frequent letters in the distribution to be selected more often so that the word I form have the same distribution. I have the feeling there is a simple solution to this but I couldn't see anything other than the frequency function that I thought I might be able to use. I could populate an array with letters present in numbers according to their frequency and then randomly select from it but is there a more elegant solution? .......

I have a set of 5,800+ data points between 0 and 1 that I would like to multiply together. When I use PRODUCT for the whole set, the formula returns 0. However, I can use a smaller subset of the data to return a very small number. I'm curious if Excel has a closest-number-to-0 or number-of-cells-for-PRODUCT limitation. Is there another way to perform this calculation?

I need to find the most frequent number for each name in a large datatable, eg. Name1=12.
ColumnA / ColumnB
Name1 / 12
Name1 / 11
Name1 / 12
Name2 / 100
Name2 / 105
Name2 / 105
Name2 / 98
Name3 / 14
Name3 / 14
Name3 / 2
NameX / ..
Since Pivot tabels cant do the trick as far as I know, i'm clueless of how to proceed.

we use # of days per disbursement as a performance measure to ensure that we are providing out grantees with the appropriate amount of service. I keep a tracking chart that I manage with overseas partners that use these dates to prioritize the 30+ grantees in their portfolio at any given time. It would be great if this # of days to disbursement #1, disbursement #2, etc could automatically pull to show them who they have neglected.
"Sheet 1" = Overview sheet to see general information (where I'm trying to pull to)
"Sheet 2" = table to track information as the disbursements or other actions are processed per grant
Column A (on both sheets) gives the grant reference
Column B (data entry sheet) gives the date the payment was sent
When I do =SMALL(('Sheet2'!B:B),2), I get the 2nd smallest in the whole sheet, but then when I try to make an IF function to tie it to the specific grant...
=IF('Sheet2'!A:A,A2,SMALL(('Sheet2'!B:B),2)) --> this gives me a 1905 date
I've tried a bunch of different formulas and tried reformatting the dates... but I'm having very little success...

I have a problem and I can't figure out how to do this, I have tried using both macros and functions (INDEX for example). The problem is as follows, I have a dataset of 27 worksheets, each worksheet has between 30k and 60k of rows and 25 columns. They are set up as follows:
------------------1990 1991 1992 etc.
Firm_A-Variable_1
Firm_A-Variable_2
|
|
|
Firm_B-Variable_1
Firm_B-Variable_2
|
|
|
etc.
Now what I am looking for is an easy way to transpose the data, I would like to have it looked as follows:
-------------Variable_1 Variable_2 Variable_3
Firm_A 1990
Firm_A 1991
Firm_A 1992
|
|
|- ---- 2012
Firm_B 1990
Firm_B 1991
Firm_B 1992
|
|
| ------2012
etc.
It is basically impossible to do this by hand, each of the 27 worksheet has between the 3000 and 6000 firms and each firm has 57 variables (these are identical for all firms). Also the the firm names and the variable names are in the same column, these should be seperated as well (they are connected with a hyphen).

I am looking to calculate variance across a large data set and would like to know if a macro is possible to calculate for a specific unique cell ID. East, Central, or West and calculate variance across that region.
For instance, in my data set if I have something similar to below. How would I calculate variance in the different regions? Is it possible to automate this process? Also could the Analysis ToolPAk be used instead or in conjunction?

I have the following structure in values found within a large dataset
6A-6200 A
6A-6156-A
I used =SUBSTITUTE(CELL," ","") to remove the space in the first value: Works fine
I am trying to remove the 2nd occurence of the - in the second value: Desired Result 6A-6156A
And how I may be able to complete both within one formula.

I am accustomed to using filters to find a lot of my information in large datasets.
However, now I am trying to use formulas to return specific values. For simplicity's sake, I have included a sample below with a couple types of scenarios I am looking to solve through the use of formulas. Would this involve sub-arrays perhaps?

I have a large dataset. under the heading Theme there are blocks of text, ie not single words. i have created a simplified version below
Sample table:
StateThemeVictoriatradeNew South Walestrade, ownershipNew South WalestradeVictoriaownership,
test textVictoriatest text, tradeVictoriatrade, ownershipVictoriaownership, trade
I want to count, for example the number of times the words 'ownership' OR 'trade' appear for Victoria.
The formula i am using is doubling up on the last 2 entries.
This is what I have:
=SUM(COUNTIFS(A2:A8,{"Victoria"},B2:B8, {"*ownership*";"*trade*"}))

I have a large itemised call bill that i need to do some regular analysis on and wondered if I could automate most of it.
In column C is a list of mobile numbers, in column F the numbers they called (this is an itemised bill so each line represents one call, meaning each number has multiple rows) finally in column K is the cost of each call.
I want the macro to look through column F (number called) and if there are less than 5 instances of that number that are under 0.30 each in cost to be deleted.
Example: if in column F the number 07500 100100 appeared once with a cost of 0.29 I want it deleted but if it appears 6 times with an accumulated cost of 3.50 i.e. more than 0.30 per call averaged out, then i want it to remain on the sheet

I have the following two bar charts. (see links below). I would like to overlay both these bar charts together and obtain the chart shown in link 3.
For example, at 4.4 GHz and 1.8m antenna, two values (downtime/year) are possible 15 min or 557min. This is represented in the third figure Since the first chart contains small values and the second chart contains large values for the x-axis, will I able to change this to log scale for ease of analysis?

I've been unsuccessful in trying to write a formula that retrieves a single result based on two criteria (from a large set of data on a separate worksheet). I've tried various INDEX MATCH combinations but no luck.
A
B
C
D
E
1
DATE
TEAM
PITCHERS
RESULT
2
4/1
nyy
Sabathia
???????
[Code] ........
So this is a very simplified version of my real data set which is about 20 times this size. The first worksheet is where I want to store my retrieved results (lets say D2 for example). I want to retrieve data from the second worksheet that matches two criteria (exactly) originating from my first worksheet. The two criteria to be matched from the first worksheet are, for example, A1 (sabathia) and F2 (the date 4/8). The complicated part is the desired result should be from the corresponding K/9 column in the second sheet, which in this case (based on sabathia and 4/8 criteria) is I2 (result would be 3). It's complicated since I can't just tell the formula to look down a specific K/9 column, I need to search ALL the K/9 columns in the sheet (of which there are many). Is this even possible with some sort of nested INDEX MATCH? Any possibilities outside of VBA programming, or is that the only way?

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.

I have the desire to create a spreadsheet that will, in the end, allow me to see the frequency of certain songs I've seen by a certain band (the same band). trying to figure out the best approach in creating such a spread sheet.
What I want to do is provide the date of a concert, and all of the songs played at that specific concert. I have that info. There are 78 concerts that I need to input. However, it seems redundant for me to list, for example, "Song A" if it was played on "date X", and then list "song A" again if was played on "date Y". This is where I'm not sure what makes the most sense.
Would it be better to use the A-Z axis and provide the 78 dates of concerts, and use the numbered axis to list all of the songs that were seen/heard. Then I could put some sort of check mark in the cell that corresponds to the song and date?This way seems like more work than is necessary.

I have a chart with event timestamps (2008-06-09 14:48:15.973) and two event types (A and B) with about 12000 events in total. I want to show a chart (probably line chart) that plots the frequency of events on a time axis (e.g. very many event A last night, not so many today, etc). I figure two time series with A and B independently so user can compare visually. But I dont know how to efficiently convert the events into a counter/frequency of events variable/column.
Ive looked into DSUM, DCOUNT & FREQUENCY functions to make a new column that shows how many events have happened in the previous 10 minutes without success. DCOUNT/DSUM problem: some of the criteria fields are computed by formula (date column minus ten minutes).

I have a large list of in rows with multiple column headings: ie. Name, date, amount. I need to generate a separate list whereby the rows that correspond to a given criteria are extracted and listed sequentially.
I have attached a simple example to demonsrate what i mean.
in the attached spreadsheet, i have a column of colours, and a column of objects- RED book, BLUE hat, etc.
I'd like the criteria that i type in the green cell (a choice of colour), to generate a list of all the items that match that colour, and be displayed in the orange cells. So, if the green cell says BLUE, the list should pick out the BLUE dog, BLUE hat etc.

I am creating a spread sheet with a large amount of data.
In column a I have a list of managers, in B I have a list of employees and C, I have a list of activities that have been recorded throughout the day.
What I want to do is create a list (on a new sheet) so in column A that would bring back all the managers. Then in column B, bring back the employee that is tied to the manager from column A and finally in column C, bring back the activity that is tied to the employee.
I know how I can do this by doing list validation with INDIRECT, but with the large amount of data that I have this would take forever in a day.
Is there an easier and quicker way to do this?

I have inherited a series of Word reports containing links to charts in several Excel files. I can tell by the link in Word that one of the charts is named 'Chart 6'. Is there an easy way to locate which chart in the Excel file is 'Chart 6' (and on and on for all of the other charts linked in the Word doc)? There are upwards of 21 charts in each Excel file linked to each of the Word reports. I am using 2007 but the files are in 2003 format because of limitations of the program from which the data comes for the charts.
