How To Deal With A Non-linear Calibration Curve |
How To Deal With A Non-linear Calibration Curve - Excel |
|
I have a non-linear calibration curve that I am trying to deal with. What is the easiest way in Excel 2007 to do this? I am including an example of what I need to do. In the example I have a linear equation - this is what the data needs to correspond to. The nonlinear curve is the calibration curve. (This is only an example, my actual calibration curve has hundereds of points, so please keep that in mind when responding).
Basically, I need something of a curve fit, or look up table. When I use my sensor and get, let's say, I put 10 pounds on the sensor, but I only get a reading of 7. I need that 7 value to translate to 10 - a linear fit so to speak. So how do I take this non-linear calibration curve, and get the data to correspond to what the readings should be (linear) - I need to know if I put 10 pounds on the scale and get 7 as an output, that it is actually 10, not 7. Thanks for any help!

So I've got some data, which has the approximate form of a sine function. I want to find all the x-axis intercepts. I tried using the intercept function and swapping around the y values for the x values, but it only returns 1 value (so I'd guess it uses a linear regression to estimate a single line through the axis).
I was thinking of trying a nested if/and statement but I haven't quite figured out how to do it. Basically I want to identify the two values where it switches from positive to negative and also indentify the values where it goes negative to positive, I can then fit a straight line between them to find a better approximation of the intercept (though it might not be necessary). Preferably I'd like it all one function as I'm not doing it in VBA (I might do later though, we'll see).
Can anyone suggest how I'd find these value or the x-intercept. Any help would be greatly appreciated.

Hello -
I am using Excel 2007. In prior versions of excel, when copying data, if I wanted to copy visible cells only, I would select "Go To, Special, Visible Cells Only" and then copy a range a cells. The default was always set to copy everything (including hidden cells), unless I specifically selected copy visible cells only.
In 2007, the default is somehow set to always copy only visible cells. Sometimes, I want to be able to copy all cells including those hidden but cannot seem to figure out how to swith this default option. I looked under Excel Options and did not see an option there.
I don't want to have to unhide and rehide everything each time i copy. I know i could do the hiding and unhiding via VBA but would prefer not to have to.
Thanks for your suggestions.

Regarding Charts in Excel:
Is there a way to have the Min and Max values adjusted dynamically for the Scale of the values being displayed ??
I know that I can use named ranges to display various sections of data -- month by month, or quarter by quarter, for example.
But when the value of these ranges vary greatly from section to section I end of having to manually go and adjust the Min and Max values of the chart scale.
For example, if I was looking at a graph of the S&P 500's prices last November, a Min and Max range of 750 to 1200 would be fine. But if I had a dynamic range established and scrolled over to view the S&P 500's prices for this past February, I would need a Min and Max range of around 650 to 850.
Is there a way to have these Min & Max values adjust automatically depending on the values being displayed ??
Thanks

Is there a way to use the new conditional formats (data bars, icon sets, etc) in PowerPoint? Basically, I'd like to create a table that shows icons based on data, like in Excel? I know I could paste a pre-made Excel table as a picture, but I'd like to avoid that if possible.

I'm trying to write a formula that will automatically take a group of football (soccer) scores, compare them with a set of predictions, and then allocate points according to how close the predictions are to the actual scores.
E.g.
Manchester United 3 - 0 Arsenal
Prediction: 4 - 1
Points: 1
I've found a formula online that works for most scores; the correct score (e.g. 3 - 0), a correct win (e.g. 4 - 1), and in the case of a draw (e.g Man Utd 1 - 1 Arsenal, and the prediction 2 -2), correct draw (but not the correct score). The points are as follows: Correct draw (Prediction = result): 4 Correct win (Prediction = result): 3 Correct win, incorrect score (Winner correct, score not): 1 Correct draw, incorrect sco 1
The formula I found online for all but the correct draw is: =IF(A3&B3=C3&D3),3,IF(AND(A3=B3,C3=D3),1,IF(AND(A3>B3,C3>D3),1,IF(AND(A3<B3,C3<D3),1,0)))))
Could someone help me work out how I can write a formula to add before the above that will check the contents of four cells (the home score, away score, home prediction, away prediction), and if the number in all 4 cells are the same, allocate 4 points? I've tried using averages, but some combinations would void this. I've also used the SUM function, but the same happens, as with MULTIPLYING.
Something like =IF(A3:D3) are equal, 4,0
Below are a few examples of what I mean:
(Result) (Prediction) (Points)
A B C D E
3 - 3 3 - 3 4
2 - 1 3 - 1 1
1 - 0 1 - 0 3
3 - 3 2 - 2 1
Apologies in advance if I haven't explained this clearly enough.
Thanks

I have a spreadsheet set up with an employees information, including the start date. After each year that the employee is working, he gets bumped up on the pay scale. For this reason, I only need to know how many years the employee has been working, rounded down to the nearest year.
This is what I have so far (hire date is in column B):
=((TODAY()-B4)/365)&" YEARS"
This function gives me a number with many decimal places.
I tried:
=ROUNDDOWN((TODAY()-B4)/365),0)&" YEARS"
It tells me I have too few arguments. Please help!

I would like to copy a small table from Word into one cell in an Excel
worksheet. The first column of the table is a list of numbers. I tried
converting the table into text with manual line breaks and tab stops to
divide columns and rows, but that didn't solve my problem.
Excel pastes the data into several rows. When I try to merge them, I
get a warning that the selection contains multiple data values, and
merging into one cell keeps the upper-left most data only.
What I tried that didn't work:
* Formatting the Excel cells as text before pasting the data.
* The various options for "Paste Special." The closest I got was
inserting the table as a Document Object, which could be a workaround,
I guess.
What I am saving for when all else fails:
* The obvious solution of copying row by row into one Excel cell.
The data in the table is information about my dad's medications. I
would like to have reference charts of how to identify the strength of
each tablet by its color and markings. I got the info from the
manufacturers' websites and entered it into tables in Word, which I
would like to copy into a more comprehensive file I am creating in
Excel. The first column of each table is the strength of the tablet,
entered as 1 mg., 2 mg., etc. The subsequent columns describe the
shape, color, and markings. There are 3 tables, each with about 4-5
rows.
Is there a way to copy each one - whether as a table or as text - into
a single Excel cell without losing data?
Many thanks.

Ran into a problem I've never seen before. When dragging a cell across that contains a sum equation the result was the following cells with the same value. Inside the cell it showed what would be the correct new equation, but the value was still from the original cell. Any ideas on what's causing this?
If I double click the cell and then hit enter it will re-total the area and then give me the correct value, but I'd obviously rather is just work right the first time.

Also, I cannot move the Pivot Table from the new Worksheet it is created in, to my existing Worksheet.
I am running Excel 2011 for Mac.
I have a Worksheet with a small amount of data, and when I click the Pivot Table button it automatically creates the Pivot Table in a new Worksheet. The Pivot Table data is fine, but I want it to display alongside the source data.
I've tried using the Move Pivot Table option and choosing to Create Pivot Table in Existing Worksheet and choosing a source cell alongside my current data, but nothing appears. Also, I checked in Edit menu and found that the Pivot Table appears to have not even been created/moved because there is no option to undo it.
Appreciate any help, let me know if you have any further questions.

Hey there,
I have been tasked with introducing userforms into an excel sheet and tbh I'm quite amazed that excel has this capability of adding userforms to excel sheets.
Anyway, I have 2 columns of data in an excel sheet and I wish to add this to a userform so that the userform displays the 2 columns beside each other with headings, like a table. The user should then be able to select a particular row and insert it into the specified cell.
I would also like the user to select a row on the table and then be able to bring up another table depending on the row selected...basically so that the user can draw deeper into the information that they require.
I have an example excel sheet where I have 2 sheets. One sheet is the user entry sheet called User Entry Screen. the next sheet is the tables sheet where my tables are held. Once the user selects the cell shown in the example sheet, it should then bring up the user form. the user then, depending on which item clicked, then gets shown the next window with a table and info on it. then user should then be able to select an item and the cells on the user entry screen would then get populated.
Personally I think this is a really tricky challenge and any help with doing this would be extremely appreciated.
I'll post up further comments as I am trying to work my way through it!
Thanks,
Jag

Hello,
I have two columns of data: column A contains the date and time in the form dd/mm/yyyy. Column B contains a number value. All the times are in order, so column A looks like:
01/01/2007
02/01/2007
03/01/2007
I have data from 2007 to 2010. I need to calculate an average daily value (in column B) for each month, and display it in column C. So, for January, I need to calculate the average of 31 days, February, 28 days, etc.
Is there a function I can use to do this? I've been trying the AVERAGEIF formula but can't get it to work. Any ideas would be much appreciated!
Many thanks,
Caitlin

Does anyone know if there is a customer format I can use to change the percent value of a cell to basis points? I tried creating my own, but was having difficulty. For example, if the cell value in A1 is 2%, I would like to have it say 200 basis points instead.
Thanks.
Thanks.
I have a set of data about with approx 7500 cells all contained in one column. The data has a series of peaks that happen, and I need to identify each peak value and place it in a cell. The peak does not occur at regular intervals but they are somewhat regular, as in within 130-230 data points. So, if one could find the first peak in the first 200 cells, identify it and store it somewhere, then look in the next 200, store it, etc. I don't know how to do that in excel. Please help
Thanks

Is there a way to force Excel to stop calculating a formula?
Excel showing "Not Responding" and is grayed out. I've tried to use Task Manager to stop the application, but as soon as open up Excel it goes right back to opening the spreadsheets and starts calculating again. I have spreadsheets saved, so don't have to recover.

Okay, so I tried (for hours) to find a solution to this and have finally gotten frustrated to the point where i think asking here will be my best bet.
Basically I want to export data from excel worksheets to various places on a word document I had. I have created a word template as well as bookmarks for that template, as that seems to be the recommendation for performing such a task with excel.
My problem is ... Now what?
I basically have 1 constant worksheet that contains all my affiliates info (Name, Address etc), which i'd like to use to populate some bookmarks in my word template, and then i have another worksheet for the previous month, indicating sales etc for that affiliate. I intend on adding a new worksheet every month that i would use to create new invoices.
Furthermore, i'd really like to be able to update a new file (or perhaps a new page on the same file) for each company with the use of a button, similar to the one's you'd see in an access form.
Can anyone help? Let me know if you need me to clarify.
Thanks!

Hey everyone,
I'm really hoping someone can help me with this...
I need to plot percentages over time in a line graph in excel. I don't want to have to do a percentage equation in the spreadsheet, I just want excel to take two sets of values and display the percentage in the chart. For example, I need B1 as a percentage of B2 for week 1, C1 as a percentage of C2 for week 2, etc....
Can someone please offer a suggestion for how to do this? I would really appreciate it.
Also, would it be possible to link data from other sheets in the workbook into one single chart?
