Get Values For Trendline To Populate In Cells?
Dec 4, 2012
I have been doing some statistical anaylsis in excel and have been using trendlines within scatter charts quite a bit.
I know excel can display the equation of the line as well as the r-squared on the chart. Is there any way to get the values for the trendline to appear in a cell next to the corresponding chart data? Of course, I can simply enter the formula myself that is given on the chart, but I am wondering if there is a way to do it automatically.
I have included the data below along with the trendline value that I calculated by manually entering the formula from the scatter chart.
Code:
YXTrendline Value
$78.990.53$79.79
$78.730.53$79.73
$80.550.52$80.88
[Code]....

I need VBA to copy the values from a treadline output box on a chart to a new sheet. The macro recorder produces the code below, but I need to make the 5th line generic so that the code will apply to any workbook. The code below will not run without the "Windows("Test.xls").Activate" statement, which restricts the code to a workbook of a specifc name (Test.xls). How can I make this run for any workbook name?
Sub CopyTreadlineData()
Sheets("A").Select
ActiveSheet.ChartObjects("Chart 1").Activate
ActiveChart.SeriesCollection(1).Trendlines(1).DataLabel.Select
ActiveWindow.Visible = False
Windows("Test.xls").Activate
Sheets("Beta").Select
Range("B15").Select
ActiveSheet.Paste
End Sub

i have a workbook that contains a series of worksheets. the workbook is a master document list. the first worksheet contains no data. the remaining worksheets are arranged so that A1 has the document number, A2 contains the document title, and A3 contains the review date. Id like to create a search macro that can search for the string entered into textbox1. if this is a number, the macro should search A1:A50 of all but the first worksheets in the workbook, and if its text, the macro should search B1:B50 of all but the first worksheets.
the macro should then select the cell containing what was searched. then id like the macro to prompt me and ask if id like to modify the reviewed date to todays date. d like to be prompted to continue searching for other records if they exist, and after that loop has finished to set the focus back to the search textbox.

is it possible to export a trendline equation from a graph to a cell, or at least to export the coefficients? If yes, how?

i have a function in a cell (that works) to extract coefficients from a range of cells in a workbook:
VB: =INDEX(LINEST(CP25:CP27,CQ25:CQ27^{1,2}),1)}
i have variables for cp25:cp27 and cq25:cq27 already defined in my vba code. the values for these in the case i am working on are as follows (returns 110.5):
cp25 = 560
cp26 = 570
cp27 = 580
cq25 = .414
cq26 = .479
cq27 = .536
1) how to do this function in VBA only - this is part of a UDF and cannot have any helper cells
2) how to refer to 560,570,580 as a 'range'. is there a way to put these six variables into my ranges for later processing?
All of the google searches i have deal only with linear regression, taking from existing graphs, or say to just use the function i have above.
I have tried
VB:
Var = Application.WorksheetFunction.LinEst(Sheets("references").Range("CP25:CP27"), Sheets("references").Range("CQ25:CQ27^{1,2}"), 1)
[COLOR=#333333][/COLOR]
but return #value! errors. when i remove the ^{1,2} portion, i do return a value but it is incorrect (returns 160), what is the correct syntax for adding in the ^{1,2}? if you do that would be fantastic, but brings me back to issue #2 in that i need to refer to my variables in the vba code and not this range (as they will eventually be going away).

wish to write an VB macro in Excel (2003) that populates a 6 row by 10 column matrix (for a 3 D graph) by inserting values from matrix row column headers in cells in another worksheet and using goal seek to derive a value which will be pasted in the respective cell in the 6X10 matrix
Specific example: Matrix (Row Headers A2 to A7, Column Headers B1 to K1, Cell values are in B2 to K7). Please note row and column headers are numerical values since this is for a 3D graph
Macro to be written
Pick a value (numerical) from row header A3 in Sheet A and paste it in cell B6 in another sheet (Sheet B). Pick anothet value (numerical) from column header D1 in Sheet A and paste it in cell B7 in Sheet B.
Run a goal seek scenario such that cell S10 in sheet B is equal to 50 by changing cell G8 in Sheet B
Copy the value chosen/optimised by Goal Seek from cell G8 in Sheet B and paste it in Cell D3 (which is the relevant cell for the values for intersection of headers A3 and D1) in Sheet A
Macro should populate all cells in the matrix in Sheet A (matrix cells to be populated are B2 to K7) in a similar fashion
The macro should be locked in to the cells which are either being copied from or pasted into so that it still references them even if new columns or rows are inserted.

I am using Excel 2007. I have two sets of data. y-series is 58.61, 58.66, 58.71 and 58.76. x-series is 0.8313, 0.8309, 0.8305 and 0.8301.
I am trying to fit a quadratic function to this data. When I plot a curve and fit a trendline I get the coefficients for the equation ax^2+bx+c
a=1.3939e-11
b=-125
c=162.5225
The plotted line seems to fit the data fairly well.
However, I want to use the linest function and I am using the formula:
=INDEX(LINEST(B2:B5,A2:A5^{1,2}),1,1)
I change the index column number as appropriate to get the coefficients:
a=-75.23775
b=0
c=110.603763
The coefficients from linest seem to be way out. how I can get the output from linest to be the same as the trendline?

I'm in the middle of designing a sheet that (amongst many other things) takes the equation of a graph trendline, pastes it, and calculates the various values along it. I can do it by hand, but when I try to record a macro, it doesn't register that I've highlighted the equation and hit copy. Here's the code I'm working with:
Sheets("Graphs").Select
ActiveSheet.ChartObjects("Chart 1").Activate
ActiveChart.SeriesCollection(1).Trendlines(1).DataLabel.Select
Selection.Copy
ActiveWindow.Visible = False
Windows("Copy of HRA Design calculator1.xls").Activate
Sheets("Binder @ max. stability").Select
Range("A1").Select
ActiveSheet.paste
The problem is line 4 - it can't copy because the text isn't selected.

I'm trying to determine the percentage rate of change in a trendline. I've got a sales chart with 90 days worth of sales figures. I can see that the trendline is trending down, but I'm not sure exactly how much.
If you take the first data point in a trendline and subtract it from the last data point and then divide that by the first it should give you the percent change. Excel must be able to do that math for you but I can't even figure it out to save my life. I can't even figure out how to display the first and last data point much less the "rate" of change I'm looking for.

Within a userform, I want to populate five combo boxes and with the values of 1 - 10. I looked through several excel websites and found several solutions. However, I could not figure out how to adopt their solutions to my specific case.
My naming convention for the combo boxes are: cmboPeriod1, cmboPeriod2, ... , cmboPeriod5.
[Code].........
I know my with statement is incorrect. I know the compiler will automatically think 'cmboPeriod' is a variable. I just don't know how to get it 'cmboPeriod & j' to do what I really intend for it to do.

I recorded a macro that finds a non-blank cell in a table (always in A25:H39), populates it with values from another tab, prints it, copies it into another worksheet and clears the contents of the form but it's painfully slow. take a look at it to see if it could be modified to run faster?
VB:
Sheets("Cash Form").Select
Dim lastrow As Long, nextrow As Long
lastrow = Sheet12.Cells(Rows.Count, "A").End(xlUp).Row

I have workbook 1 and workbook 2.
I need to lookup the value in workbook 2 in order to populate workbook 1.
If workbook 2 value = NA, then "" in Workbook 1
If Workbook 2 value > workbook 1 value, then Workbook 1 value
If workbook 2 < workbook 1, then Workbook 2 value.
Should be simple. Keep getting errors in formulas @if or @lookup.
It would be nice to know by worksheet within same workbook as well.

I have my lookup value in column A. The vlookup result in Column B.
=VLOOKUP(A1,ALL!B2:Y10482,2,FALSE)
I now want to drag this across to populate and return values up to column Y.
When I drag the formula or copy it to Column C it does this:
=VLOOKUP(B1,ALL!C2:Z10482,2,FALSE)
The lookup value, table array, and column index number have now changed to column B, C:Z, and 2, when I need it to increment like this:
=VLOOKUP(A1,ALL!B2:Y10482,3,FALSE)
The only thing I want to change as I paste it into the adjacent field is the col_index_number.
Is there a way to do this horizontally without manually changing the formula 26 times?

I am trying to find a way to populate a cell with spaces (like " "). But I want to populate a cell based on a number in another cell.
For example, if cell A1 has a value of 7 in it, I want to make another cell have seven spaces (or seven letter Z's, or anything), but I can't figure out how to do it. Then I want to use that equation to do any number of spaces based on the number in the cell, whatever it is.

I used this forum to find code to convert a matrix to a list. But I need to repeat then change one column - "Product".
The "Prodcut" vlaue needs to repeat unitl it changes.
I have attached a file with the code in module 1, and samples of where I am, and where I need to be. I think I am close!

I have source data sheet like this one: source_sht1.PNG
I want to populate the range of the same data from Column A to the separate sheet2. For example: From Cloumn A within the same "AAA' values (range: A4:A7) i want to populate all data from Column B to E (highlighted in orange). The second sheet should look like this:
Sheet2.PNG
The macros should end when Column A value = empty with this so i could finish my macro .

I have systems that spit out text log files showing machine performance. Each log file has about 5000 lines of data in it which I import into excel for processing. One of the columns has a machine voltage that changes with the machine state. There might be 10-15 discrete values (like 500V, 800V, or 1000V) within the 5000 lines. I'm trying to populate a list box with just the discrete values so the user can choose what state to process for charting. Some log files might only have 2 or 3 voltages others might have 15 or more so it isnt fixed. I've been trying to use an advanced filter with copy to location and unique records selected but I run into problems with the variable size of the list and with the fact that the header repeats periodically and I can't seem to screen that out of the list.

My sheet goes from monday to friday on the coulombs. On the rows i have various data sections for each day. I would like the data on the last day (any day after monday) that there is data for a sheet to input that data into the monday slot when the "master date" is changed on the cheese sheet. The idea here being that the script will take the last entered data for a given sheet, and put it into the monday coulomb on the same sheet when the date is changed. This is kind of hard to explain so if you need clarification let me know. Attached is the sheet i'm working with.

11/30/19990.134171
12/31/19990.149113
and also a series of the 365 days that comprise these 12 months.
I need to populate each of the 365 days within this period (1/1/1999-12/31/1999) with its corresponding value for the month, i.e. 1/21/1999 (and all days in Jan) will take 0.155375 and 5/4/1999 (and all days in May) will take 0.17128.
How I should set out my data and which formulas I need to use?

I am working with a worksheet that has some cells merged e.g. A1 and A2 are merged together as 1 cell. I am using cell offset to reference values from the worksheet assign them to variables then populate another worksheet with their respective values. I noticed that cell.offset(row,column).value is not retrieving a value when merged cells are mixed with non-merged cells within a given row. Is there another method/function I can take advantage of here?

What these line of code mean (the ones in red).
Code:
Private Sub UserForm_Initialize()
Dim v, e
With Sheets("maintenance").Range("c2:c500")
v = .Value
End With
With CreateObject("scripting.dictionary")

Note : I simple tried to check the value of v by giving msgbox (v), just below the line v = .Value.
But I got run-time error 13 : Type mismatch error.
