Been working on an industrial solution since December. Narrowed it down to daily 4 variables.
Columns of variables A B C D
Day 1 Results 2 3 2 2
Day 2 Results 2 3 2 3
Using the and function, I combine the day to day change into a single number 23222323
I then have a table with all possible outcomes
Lookup Table Of Possible Results In Ascending Order (Expressed as whole numbers)
22122212 Fail
23222323 Good
23233333 Poor
33202322 Excellent
33333322 Undetermined
I can't figure out how to look up the daily result of a built up number using the formula A1&B1&C1&D1&A2&B2&C2&D2 to a table of real numbers in order to return the result "Good" in this example.
Try this:
=VLOOKUP(A1&B1&C1&D1&A2&B2&C2&D2,<lookup_table_range>,2,0)
If your 22122212 (for example) is stored as a number in the lookup table you will need to convert the lookup value to a number as well.
=VLOOKUP(--(A1&B1&C1&D1&A2&B2&C2&D2),<lookup_table_range>,2,0)

I am looking for a way to make a specific graph in Excel and I can't find a solution in Excel or on the web.
I have data about an online training with people completing parts of a course at a certain time:
FullName
Course
TIME
Name-A
Part 1
23/03/2022 10:38
Name-A
Part 2
23/03/2022 12:07
Name-A
Part 3
23/03/2022 16:55
Name-B
Part 1
11/03/2022 15:14
Name-B
Part 2
22/03/2022 12:08
Name-B
Part 3
28/03/2022 16:06
Name-B
Part 4
30/03/2022 14:55
Name-B
Part 5
18/04/2022 08:13
Name-C
Part 1
11/04/2022 15:25
Name-C
Part 2
20/04/2022 13:50
I would like to have a specific graph of this data:
On the vertical axis: one row for each user' name: Name-A, Name-B and Name-C.
On the horizontal axis: continuous time (say, in days) From the minimum time in the table (or less) to the maximum (or more)
Series of plots for the data: Each part of the course (from Part 1 to Part 5 here) would be a series of dots of a specific color, placed on the right row (for a learner's name) above the corresponding time on the horizontal axis.
Do you have any idea on how it could be achieved?
All the best, R.S.
Edit: The table does not appear as in the preview so i try to add a screenshot:
Screenshot of the table
So one way to visualise this as mentioned in the comments is to create a separate series for each person and show passing each part of the course as a vertical step:
It's based very loosely on this but I've set each day in the date range as the x-coordinates and used a lookup to transform the data in H2
=RIGHT(XLOOKUP($G2+TIME(23,59,59),FILTER($C$2:$C$11,$A$2:$A$11=H$1),FILTER($B$2:$B$11,$A$2:$A$11=H$1),0,-1))+(COLUMN()-COLUMN($G$1))*10
pulled down and across to give
Explanation
The data for the graph has dates spanning the times in the raw data for its x-coordinates (column G). I generated it manually but could have used Sequence in Excel 365.
There are three columns of y-values, H to J, generating a separate series for each person. The three lines are initially spaced out by 10 units based on the column number. In the formula above, the raw data is filtered by the person's name so the headers in columns H, I or J match the names in column A in the raw data. Xlookup is used with 'next smallest' match so where the date in column G is greater or equal to the date/time in column C it will return the corresponding course from column B. Because column C actually contains date/times, I have added almost 24 hours when matching the date in column G to make sure that a match is found if the day is the same, regardless of time. In a case like Name-A, where three courses are completed in the same day, this will automatically select the last one (Part 3). Then I take the right-hand character of the course name (which is a digit in the sample data) and add it to the relative column number multiplied by 10. If there is no match, Xlookup returns zero so you just get the initial value for each series (10, 20 or 30), otherwise the result will be an increase by one unit each time a course is passed. If you couldn't assume the last character of the course name was a digit, you would need a lookup to assign a number to each course name.
The data is then plotted on a scatter graph with points joined by straight lines. I had to adjust the x-axis manually to make the range correct and the labelling clearer.
This could be done without Excel 365, probably using Aggregate to get the highest row number with a condition on the name and date.
EDIT
I could have achieved the same result much more easily using Countifs to find how many courses had been passed by a certain person by a certain date:
=COUNTIFS($A$2:$A$11,H$1,$C$2:$C$11,"<="&$G2+TIME(23,59,59))+(COLUMN()-COLUMN($G$1))*10
This wouldn't have needed Excel 365. If you needed to give different courses different weightings, you could do this with a sumproduct and a lookup, also fairly straightforward.
I spent hours trying to look for a solution and I feel like I got close but figured asking would be the best way.
Lets say I have a table with 2 columns, column A is an item, and column B is a price for the item. This table has 12 entries. What I would like to do is generate additional tables of 6 entries that do not exceed a certain price. see below for example. The number i want these table to not exceed is 50,000.
for example the first entry could be an apple at 9,000 value. the apple is column a, and value column b.
Can someone help with a way to generate all combinations of 6 items from column a, that do not exceed a combined price of 50,000 in column b?
With 12 items you have 212-1 or 4095 possible combinations of products. These can map into the 12 bits of a 12-bit binary number. It is not difficult to write a macro to calculate the total cost of each combination and then filter the result to display results less than or equal to 50,000.

I am working on a model of charging load of electric vehicle. I am attaching a link to an excel workbook for your better understanding.
Column B contains random time values
Column G to P represents houses and each house can have 1 car. So the each time values needs to be distributed in one column. Now when a car is plugged in, its load stays constant for 3 cells.
I want excel to randomly distribute these cars e.g. 4 cars to 4 houses and leave others blank.
what i can think of is, to assign each time a random house then use IF formula with AND function to match random times with time series and second condition to match random houses with columns 1-10.
the problem i am facing is, the formula gives a value error and only works in the rows with has random generated time in front of them screenshot. I know there is a very small thing that i am missing. please help me find it
Regards
workbook
=IF(ISNA(MATCH(G$5,$C$6:$C$9,FALSE)),"",IF(AND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE))>=$F6,INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE))<=$F6+TIME(0,30,0)),11,""))
The two elements in the AND find the house number in column C and return the corresponding time in column B.
The first element compares the time in F to that time. The second element compares the time + 30 minutes to F (three cells). If it's between those two times, it gets an 11.
The ISNA makes sure that the house in question is on the list. You could also use an IFERROR, but I prefer the precision of ISNA.
Update
If you want the values to wrap around, you need to OR compare to the next day.
=IF(ISNA(MATCH(G$5,$C$6:$C$9,FALSE)),"",IF(OR(AND(ROUND($F6,5)>=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE)),5),ROUND($F6,5)<=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE))+TIME(0,30,0),5)),AND(ROUND($F6+1,5)>=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE)),5),ROUND($F6+1,5)<=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE))+TIME(0,30,0),5))),11,""))
That formula structure looks like
=If(isna(),"",if(or(and(today,today),and(tomorrow,tomorrow)),11,"")
This formulas already getting too big. If you triple it for your three voltages, it will be huge. You should consider writing a UDF in VBA. It won't be as quick to calculate, but will probably be more maintainable.
If you want to stick with a formula, you could put the wattage in row 4 above the house number. Then in another table, list the wattages and minutes to charge. So in, say, B12:C14 you have
3.7 120
11 30
22 15
Now where you have 11 in your formula, you'd have G$4 and the two placed you have TIME(0,30,0), you'd have TIME(0,INDEX($C$12:$C$14,MATCH(G$4,$B$12:$B$14,FALSE)),0). I re-arranged some stuff to make it more 'readable' (but it's still pretty tough) and here's the final formula
=IF(ISNA(MATCH(G$5,$C$6:$C$9,FALSE)),"",IF(OR(AND(ROUND($F6,5)>=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE)),5),ROUND($F6,5)<=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE))+TIME(0,INDEX($C$12:$C$14,MATCH(G$4,$B$12:$B$14,FALSE)),0),5)),AND(ROUND($F6+1,5)>=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE)),5),ROUND($F6+1,5)<=ROUND(INDEX($B$6:$B$9,MATCH(G$5,$C$6:$C$9,FALSE))+TIME(0,INDEX($C$12:$C$14,MATCH(G$4,$B$12:$B$14,FALSE)),0),5))),G$4,""))
I'm trying to perform an AVERAGEIFS formula on some data, but there are 2 possible results and as far as I can tell AVERAGEIFS doesn't deal with that situation.
I basically want to have an ELSE inside it.
At the moment I have 2 ranges of data:
The first column only contains values 'M-T' and 'F' (Mon-Thurs and Fri).
The second column contains a time.
The times on the rows with an 'F' value in column 1 are an hour behind the rest.
I want to take an average of all the times, adjusting for the hour delay on Fridays.
So for example I want it to take an average of all the times, but subtract 1 hour from the values which are in a row with an 'F' value in it.
The way I've been doing it so far is by having 2 separate results for each day, then averaging them again for a final one:
=AVERAGEIFS(G3:G172, B3:B172, "M-T")
=AVERAGEIFS(G3:G172, B3:B172, "F")
I want to combine this into just one result.
The closest I can get is the following:
=AVERAGE(IF(B3:B172="M-T",G3:G172,((G3:G172)-1/24)))
But this doesn't produce the correct result.
Any advice?
Try this
=(SUMPRODUCT(G3:G172)-(COUNTIF(B3:B172,"=F")/24))/COUNTIF(B3:B172,"<>""""")
EDIT
Explaining various steps in the formula as per sample data in the snapshot.
SUMPRODUCT(G3:G17) sums up all the value from G3 to G17. It gives a
value of 4.635416667. This after formatting to [h]:mm gives a value
of 111.15
OP desires that Friday time be one hour less. So I have kept one hour less for Friday's in the sample data. Similar SUMPRODUCT on H3:H17 leads to a value of 4.510416667. This after formatting to [h]:mm gives a value
of 108.15. Which is exactly three hours less for three occurrences of Fridays in the sample data.
=COUNTIF(B3:B17,"=F") counts the occurrences of Friday's in the B3:B17 range which are 3 occurrences.Hence 3 hours have to less. These hours are to be represented in terms of 24 hours hence the Function COUNTIF() value is divided by 24. This gives 0.125. Same is the difference of 4.635416667 and 4.510416667 i.e. 0.125
Demonstration column H is for illustrative purposes only. Infact Friday accounted values that is 108.15 in sample data has to be divided by total data points to get the AVERAGE. The occurrences of data points are calculated by =COUNTIF(B3:B17,"<>""""") with a check for empty columns.
Thus 108:15 divided by 15 data points give 7:13 in the answer.
Revised EDIT Based upon suggestions by #Tom Sharpe
#TomSharpe has been kind enough to point the shortcomings in the method proposed by me. COUNTIF(B3:B172,"<>""""") gives too many values and is not advised. Instead of it COUNTA(B3:B172) or COUNT(G3:G172) are preferable. Better Formula to get AVERAGE as per his suggestion gives very accurate results and is revised to:
=AVERAGE(IF(B3:B172="M-T",G3:G172,((G3:G172)-1/24)))
This is an Array Formula. It has to be entered with CSE and further cell to be formatted as time.
If your column of M-T and F is named Day and your column of times is named TIME then:
=SUMPRODUCT(((Day="M-T")*TIME + (Day="F")*(TIME-1/24)))/COUNT(TIME)
One simple solution would be to create a separate column that maps the time column and performs the adjustment there. Then average this new column.
Is that an option?
Ended up just combining the two averageifs. No idea why I didn't just do that from the start:
=((AVERAGEIFS(G$3:G171, $B$3:$B171, "F")-1/24)+AVERAGEIFS(G$3:G171, $B$3:$B171, "M-T"))/2
I have a data table in Spotfire which contains two columns I'm interested in: Time (31/01/2015 for example), and Value (integer).
I want the most recent date (e.g. December 2015) to be set as the current time. Then I want to select Value based on previous 1 month, 3 months, 6 months etc. So if I want all the values for past 6 months it should Sum(Values) for Dec.2015, November.2015, October.2015, September.2015, August.2015 and return that.
So far I've only been able to accomplish this by manually performing the task in Excel before I insert it into Spotfire so is there any way to create a calculated column for each of the periods I want? (Past month, 3 months etc.)
There's likely a number of ways to solve this, but I'm going to give one suggestion and we'll see how it fits your specific case.
You can add a calculated column for each timespan you are interested in, defined like this:
Sum(if (DateAdd('month', 3, [Time]) >= Max([Time]), [Value], null))
This example would get you a column with all the values that have occured in the past 3 months, replace the number 3 in there to modify to the timespans you are interested in. A full sum of the calculated column would get you the total for that timespan.
Might be nicer to use a boolean column instead of duplicating the value column. Then your calculated columns would be defined as:
DateAdd('month', 3, [Time]) >= Max([Time])
When calculating totals you would then use an if statement using the calculated column, like this:
Sum(if([3Months],[Value],null))
where [3Months] is a boolean column.
