I'm trying to calculate the payment_amount in the FV formula so I could plot the growth chart over certain period. The difference is that I know what FV I want to reach, and I know the rate and number_of_periods.
I created this example to illustrate the problem:
https://docs.google.com/spreadsheets/d/15anlU1i9XWAgI-J-6lFmWSsLRgOck_iZGitKfPKmEt4/edit?usp=sharing
You can see two lines in the chart.
The purple line is a simple straight line from $0 to $1.5M. The data is coming from the FV formula in the column B.
The green line is more what I'm looking for. The data is coming from the FV formula in the column C, but I had to manually input the payment_amount value.
Is there a way to automatically calculate the payment_value based on the rate and the number_of_periods?
Is not as exact as your value but you can use:
=-FV(F8, 1, -PMT(F8,F11,1, F5), 0)
I stated F11 as number of periods in case you want to change it dinamically. You can also use this sequence to have the full calculations in one cell:
=Scan(0, SEQUENCE (F11),LAMBDA(ag,v,-FV(F8, 1, -PMT(F8,F11,1, F5), ag)))

I need to sum a range of cells in each row but the cells have text that has to be ignored. For example, a cell may be 2= Moderate and I need the "2" for the sum.
If I use this formula, for one row, I get the correct result:
=SUM(SPLIT(REGEXREPLACE(CONCATENATE(F2:AB2), "[^\d]+", "|"), "|"))
Now I want to use ArrayFormula to repeat this formula for every row. With everything I've tried, I get the result of the first row repeated for every row. Example: if the result of row 2 is 14, then every row will show 14.
Here is the simplest formula I have tried:
=ArrayFormula(IF(ISBLANK(F2:F),"",
SUM(SPLIT(REGEXREPLACE(CONCATENATE(F2:AB2), "[^\d]+", "|"), "|"))
))
For the innermost range that is not getting changed to represent the current row, I have tried using indirect with relative references CONCATENATE(INDIRECT("R[0]C6:R[0]C28")) with the same result.
Is there a way to get ArrayFormula to work here?
Edit:
Adding link to demo version of sheet: https://docs.google.com/spreadsheets/d/17OYq3tjP1A1H8SPYAoAAlxOlrsFV2R5CQT3MNc7ZkMo/edit?usp=sharing
use:
=ARRAYFORMULA(MMULT(IFERROR(REGEXEXTRACT(
INDIRECT("F2:AB"&MAX((ROW(A2:A)*(A2:A<>"")))), "^\d+")*1, 0),
TRANSPOSE(COLUMN(F:AB))^0))
It is always difficult to write formulas without seeing your sheet, data or layout. But based solely on what you've provided, you can try this:
=ArrayFormula(IF(F2:F="",, MMULT(IF(ISNUMBER(F2:AB), F2:AB, 0), SEQUENCE(COLUMNS(F1:AB1), 1, 1, 0))))
MMULT performs matrix multiplication, which is difficult to explain but which essentially multiplies every element of one matrix by every element of another and adds the results by row.
Each element of each matrix must be numeric. So the formula creates the first matrix with an IF statement that replaces anything in the requested range that is a number with itself and anything that is not a number (i.e., text or blanks) with a 0. The SEQUENCE forms the necessary second matrix by creating a vertical "stack" of 1's that is the same width as the first matrix. And since anything multiplied by 1 is the original number, we get the correct result.
ADDENDUM:
After reading the additional comment by the OP and seeing a sample sheet, this is the MMULT setup needed:
=ArrayFormula(MMULT(VALUE(REGEXEXTRACT(FILTER(F2:AB, F2:F<>""), "\d+")), SEQUENCE(COLUMNS(F1:AB1), 1, 1, 0)))
My title might not be very specific, so I'm going to try to explain a little better.
The sheet is divided into a name(Column A), containing a certain number of values(Column B), that get added together to a total in Column C. Furthermore, Column D, E and F contains the values I want the Total in Column C multiplied by. These first columns A to F I just fill in manually, but I would like a function to calculate the Columns I've called x, y and z total (G, H and I).
I see a pattern in this, I just can't figure out the syntax to get Sheets to see it aswell.
The pattern I'm invisioning is for each row, I want column G, H and I to take the value 3 fields to their left, and multiply it by Column C, at their row number.
Is this somehow achievable? I tried finding a solution online but I guess I don't know how to word myself.
Here's a picture to maybe make everything a little clearer
This would save me alot of time, given that I have over a hundred different rows this calculation needs to be performed on...
If something is not clear, please feel free to write a comment. I'll be following this thread quite liberally.
Thanks in advance!
You can have this formula on the first xTotal:
cell G2: =ARRAYFORMULA(if(len(C2:C),C2:C*D2:D,))
cell G2: =ARRAYFORMULA(if(len(C2:C),C2:C*E2:E,))
cell G2: =ARRAYFORMULA(if(len(C2:C),C2:C*F2:F,))
I created a sheet with the same results you had before, but this time you don't need vertical columns, just say in the # of Values column how many numbers you should have below. You just need to input the values with the grey columns.
Note: This is assuming you will always have growing vertical numbers like 1,2,3,4,5. In the new sheet you just need to set 5 in the column and it will calculate the result.
Please make a copy of this sheet and edit as you wish.
Sheet
You can use a single, simpler formula for this in cell G2
=ARRAYFORMULA(if(C2:C="",,C2:C*{D2:D,E2:E,F2:F}))
I'm trying to count the number of empty cells that exist in a column between each non-empty cell but haven't been able to work out how.
Using this, I'm also trying to find the largest "empty distances" and locate the cell in the center of these distances.
The sheet I'm working with lists a set of marker colors and denotes the ones that are owned out of the full set of colors. I'm trying to find the largest ranges of missing colors and then find the colors in the middle of those ranges in order to find a handful of markers that would best help to fill out the spectrum.
Columns 1-6 are information- Column 7 marks whether the color is owned:
I may have an answer that helps you.
I could only get it to work using a helper column, but someone may know how to eliminate that requirement.
The helper column creates an array, basically listing the row numbers of the rows that have an "x" in your column B.
The main formula then measures the gap between each of these listed row numbers. It also checks the gap before the first "x", and after the last "x". Note that I have the data starting on row 2, which complicates the formula, but makes the sample sheet clearer - this can easily be changed to row 1 if you prefer.
={F2-1;
query(ArrayFormula(if(isnumber(F3:F),F3:F-F2:F-1,"")),
"select Col1 where Col1 > 0",0);
counta(A2:A)-indirect("F"&COUNTA(F$2:F))}
See a sample sheet here:
https://docs.google.com/spreadsheets/d/19QUFGRqTT6BqOsBrEBpTIxQCeNdRa5mzXhxQpCZ8sV4/edit?usp=sharing
Then I used a second formula to calculate the max gap between "x"s, (or before the first or after the last x).
Note that calculating the midpoint of the gaps, and doing a lookup of the corresponding mid-point colour, is something that can be added to this answer, if you share a sample copy of your sheet and share it for editing.
Let me know if this helps. I'll add more explanation to describe what the formula is doing tomorrow.
And I'll provide a second tab with the formulas adjusted to work with data beginning on row 1.
You can also get the lengths of the gaps using Frequency:
=ArrayFormula(frequency(if((B1:B20<>"X")*(A1:A20<>""),row(B1:B20)),if((B1:B20="X")*(A1:A20<>""),row(B1:B20))))
but finding the centres of the gaps and allowing for equal-sized gaps is more difficult.
This should find the position of the "X" at the end of the longest gap:
=ArrayFormula(
sum(frequency(if((B1:B20<>"X")*(A1:A20<>""),row(B1:B20)),
if((B1:B20="X")*(A1:A20<>""),row(B1:B20)))*(sequence(countif(B1:B20,"X")+1,1)<=
match(max(frequency(if((B1:B20<>"X")*(A1:A20<>""),row(B1:B20)),
if((B1:B20="X")*(A1:A20<>""),row(B1:B20)))),frequency(if((B1:B20<>"X")*(A1:A20<>""),row(B1:B20)),
if((B1:B20="X")*(A1:A20<>""),row(B1:B20))),0)))+
countif(sequence(countif(B1:B20,"X")+1,1),"<="&
match(max(frequency(if((B1:B20<>"X")*(A1:A20<>""),row(B1:B20)),
if((B1:B20="X")*(A1:A20<>""),row(B1:B20)))),frequency(if((B1:B20<>"X")*(A1:A20<>""),row(B1:B20)),
if((B1:B20="X")*(A1:A20<>""),row(B1:B20))),0))
)
and then it should just be a case of working backwards from there to the centre of the longest gap. However the formula needs further refinement to deal with the cases
(1) Where the longest gap is after the last "X"
(2) Where there is a tie for the longest gap
(3) Where there is a need to list the longest, second longest, third longest gap etc.
I have a sheet with a line chart, now I'm trying to do something maybe very simple: I would like to add to this chart a vertical line using a value in a cell.
So I have this line chart
And a cell with the date 2016/01/01, I would like to have a vertical line through all the chart on the cell date
I can't figure out how to do it...
This is a copy of that sheet: https://docs.google.com/spreadsheets/d/1oeiwmeDT8pUVqBQvoE_cqk7mZxxvD5moZr41Vp4IN2I/edit?usp=sharing
I would like to show a vertical line using the "Purchase date"
I had the same problem and created a solution to overcome limitations of Google Sheets charts.
The main idea is to create an additional line in the chart, with only two points, both with the desired date. The value of the first point is 0 and the last has the maximum value of the Y axis. This way, the line always covers the entire height of the chart.
Screenshot of the Chart
Note that it is necessary to add two new values in the X axis (highlighted in blue on the sheet). Don't worry with the fact they are repeated. Google Sheets handles it correctly.
These values can be placed at the beginning of the lists. This way, it is possible to add new values at the end of them.
This solution can be viewed in: "[GoogleSheets] Dinamic Vertical Line in a Chart"
To change position of red line, just select a different value in "Purchase date" (yellow cell).
I made a merge of my first solution with the one suggested by dimo414 and created a new solution with two variations.
In the previous version of the spreadsheet, there were only two points to draw the vertical line.
In the new version, a third point were inserted to show intersection between the line and the real curve. A new column was also created, containing only a label for the new point.
The result is:
Theses changes can be seen in green background in sheets 'Dashboard_v2' and 'Dashboard_v3' of the SpreadSheet.
To determine coordinates of the new point, two approaches were used:
Search Purchase Date directly in the dataset (see sheet 'Dashboard_v2')
If the goal is to highlight only points of intersection that belong to the original dataset, it is just necessary to VLOOKUP() the date in the dataset.
Interpolate the two points immediately smaller and larger than the purchase date (see sheet 'Dashboard_v3')
Given the points [x1,y1], [x2,y2] and a value of x (where x1 <= x <= x2), its possible to find an interpolation point [x,y] with the following formula:
y=(y2-y1)*(x-x1)/(x2-x1)+y1
Although this formula is easy to implement, find the correct points to interpolate is more challenging and requires a bit of creativity.
At first, I thought of using a JS script to make things easier, but decided to use only builtin functions.
By the way, different approaches to find [x1,y1] and [x2,y2] are welcome.
To make things easier to understand, each point coordinate is determined in a different cell (see L2:M5) and the point of intersection is in L6:M7.
Of course, its possible to join all of them in just one cell, but I thought it would be harder to understand.
To close, one more detail: According to above definition, interpolation formula is valid only if (x1 <= x <= x2). Thus, both cells C2 and M6 have protections to limit the value of 'x'.
One way is to add a label to your x-axis.
For example, this is a chart that plots weight against date, with a label "Cheat Day" on 2021-07-21
For the data:
Date
Label
Weight (kg)
Weight Goal (kg)
2021-07-19
83.85
75
2021-07-20
84.55
75
2021-07-21
Cheat Day
83.8
75
2021-07-22
84.95
75
2021-07-23
83.75
75
Go to Edit the chart > Setup > Under X-axis > Click on ••• next to your "Date" column > Add labels > Select the column "Label" as your label.
Your Chart Editor > Setup should look like this:
you can have it like this, unfortunately not programmatically. the only way is to insert a line via Drawing and position it manually where needed.
spreadsheet demo
As best I can tell there isn't a way to add a vertical marker line to a chart in Google Sheets. One option that may be "good enough" in many cases is to "Add notes to a data point" and then use "Format data point" to make the point more visible. Here's an example, from your spreadsheet:
Unfortunately one limitation with this approach is you can only label a data point in the data set the chart is displaying. In your case the date you wanted to mark with a line isn't in the data set, so this won't work directly. You might be able to introduce a separate data series consisting of just that date and then add a note to that data point, but I haven't fiddled with it enough to make it work.
I have a Google sheet that shows the number of KM a vehicle ran every day. Column E is the total distance. I want to change row background to red as soon as the value in E crosses 1000. And it should apply only to that one immediate row.
How to do it?
Select A5 to wherever suits, and apply a Conditional formatting formula rule of:
=countif($E$5:$E5,">1000")=1
You can do this directly with a formula from the Conditional Formatting option.
In my example I am shading the row in the area A1:B3 based on the values in C
Use the format cells if ... custom formula is option and put the conditions you want you range to change in there.
E.g. I am formatting my range to change to green when =$C1>=1000
Notice I don't need to change C1 to include all the rows, as it will evaluation on every for separately.
