In mid May, Anup47 asked a question in the Chandoo.org forums about the use of a VBA macro to run a number of iterations of a variable against two sets of X values, you can see the post here. It turns out that the number of iterations was 500 columns of data with each column having 27 values.
On examination of the problem, it was going to be a straight forward matter of setting up a statistical function Linest and then using the Data Table command to run each set of data through the function.
The Linest will take the input data and return the statistics that Anup wanted.
The Data Table function will feed in the source data and tabulate the Input and Output data.
This Post follows through a worked example which you can follow along, download the Sample file to suit Sample File 97/2003 or Sample File 2007/10 version. The Sample File contains a worked example of the completed model as well as a Practice Page of the original data. Download the Excel 95/2003 or 2007/10 version above.
Please note that the sample file only contains 14 sets of data as opposed to the 500 Anup47 wanted to process.
Setup
There are a few things that needed setting up before the work starts.
- Headers
- Linest Area
- Link Area
- Data Table Area
Once these areas are setup we simply use the Excel Data Table function.
Once the Data Table function has run, the results can be processed or analysed as required.
Headers
The original data was just that, a tabulation of raw data. The two X sets of Data were in Columns 1 & 2. Each Column from D onwards has a set of Y data that was to be processed.
The first thing that was required was some Headers for the Input Data.
This isn’t strictly required but it is good practice and makes it easier to tabulate and analyse results later.
Insert a Row above the first line
Put X1, X2 in A1, B1 and Y1 in D1 and then drag the lower right Black Handle across top to the right and Excel will autofill the remaining cells.
Linest Area
To get the statistics which Anup wanted we will use the Excel Linest function.
Linest is a Statistical Function that takes a set of data and compares it, in this case to two sets of X Values and produces a set of statistical measure relevant to the correlation between the data sets.
This post isn’t going to explain the intricacies of Linest and I refer you to the Links section at the end where you can read more about the Linest function at your leisure.
For our purposes we need to know that Linest is an Array Formula and requires a 5 Row x 5 Column area to be entered into. For now we will just Array Enter the function =Linest($D$2:$D$28,A2:B28,True, True) into B32:F36.
To do that select the range B32:F36, Press F2 and type/paste the equation in, then Array Enter with Ctrl Shift Enter.
Link Area
To Link the Linest equation to a Data Table we need a link cell, which we will put just above the Linest area.
For now just enter a 1 in it.
We can now go back to the Linest area and link the Linest equation to our link area using the equation, =LINEST(OFFSET($C$2:$C$28,,$B$30),A2:B28,TRUE, TRUE)
To do that select the range B32:F36, Press F2 and type/paste the equation in, then Array Enter with Ctrl Shift Enter.
What this does is allow the Linest formula to access different columns Y1 to Y500 depending on the value of the Link cell B30 which is now 1.
Data Table Area
To setup a Data Table area we need a column of Inputs which will be the Run Numbers and the Row Inputs will be links to the Input and Output Cells.
In a range J33:J46 put the values 1 to 14. These will be the Run Numbers. ie Run No 1, Run No 2 etc (Green in the example below).
Across the top of the Data Table area we can put a number of links and associated labels (Yellow and Blue)
In this case there are 4 Output links =B31, =C31, =B34 and =B33 and their associated labels above them, as well as 2 Input equations and there Labels. The Input equations are simple Offset function that retrieves a value from Rows 1 or 2 based on the value of the Link Cell B30.
These are technically not required but make data analysis and identification of individual results later on a lot simpler.
Run Data Table
We can now run the data Table by selecting the Data Table area: J32:P46
Noting that we will be using a Column Input cell and that it will link to $B$30, the Link cell for the Linest command.
What this does is takes the first value from the Column J32:J46 and puts it into B30, then the Linest command will be calculated and the results put into the Data Table area along with the Inputs.
This is repeated for each cell in J32:J46 automatically.
The final Data Table is now populated as below:
You can see by extending the Data Table input column from 14 to 500 that the full 500 columns of Input Data could easily be processed.
Results
You now have a set-off data that can be analyzed using normal statistics, Min, Max, Std Deviation etc, or can be fed into a Pivot Table/Chart for analysis etc.

I tried your code with 2003, it works.
But, I know Addpicture does not take URLs anymore with 2007 onwards, perhaps its the same with picture.insert as well.
http://support.microsoft.com/kb/928983/en-us
The above link gives the solution as "picture fill in a shape such as a rectangle".
Tried to recreate this, but it worked fine for me. I just took the image of the error you showed in the post. Is there more info that can narrow this down a bit?
Don't know if this helps?

Hi
Not sure if this is what you're after, but I just tried this
Sub Macro1()
ActiveSheet.Pictures.Insert("http://www.google.co.uk/intl/en_uk/images/logo.gif").Select
End Sub
Tied a button to it on the sheet and it seems to work; hope this helps a little
Ian
@All.. the issue is in Excel 2007. In 2003 ActiveSheet.Pictures.Insert seems to work fine. Unfortunately, I have design this in Excel 2007.. that is why I posted it here..
v2
Sub Macro1()
Set n = ActiveSheet.Pictures.Insert("http://www.google.co.uk/intl/en_uk/images/logo.gif")
With Range("c12")
t = .Top
l = .Left
End With
With n
.Top = t
.Left = l
End With
End Sub
Ian
That didn't come out very well. This positions at c12, so can change easily:
Sub Macro1()
Set n = ActiveSheet.Pictures.Insert("http://www.google.co.uk/intl/en_uk/images/logo.gif")
With Range("c12")
t = .Top
l = .Left
End With
With n
.Top = t
.Left = l
End With
End Sub
Works OK in 2007
Ian
The above codes work fines to my EXCEL 2007. Thanks.
Chandoo:
Try 'ActiveSheet.Pictures.Insert'
With ActiveSheet.Pictures.Insert("C:\Example.png")
.Left = ActiveSheet.Range("A1").Left
.Top = ActiveSheet.Range("A1").Top
End With
activesheet.pictures.insert "C:\Documents and Settings\Jon Peltier\Desktop\2007 stuff\insert_charts_2007.png"
Works for me in 2003 SP3 and in 2007 SP2.
Check the URL, and make sure you have internet connectivity.
What also works, and is newer (pictures.insert was supposedly deprecated in '97):
activesheet.shapes.addpicture "C:\Documents and Settings\Jon Peltier\Desktop\2007 stuff\insert_charts_2007.png", false, true, 200,200,100,100
Unfortunately you must specify dimensions (the last four arguments) and you don't necessarily know them. But the picture size is still related back to the original picture size, so you could use scaleheight and scalewidth to fix this.
Chandoo: I just re-read your post.
The code I posted works for me. However, I'm using a local picture. If you try to add a picture from the web, this won't work.
I remember solving this problem before by adding a rectangle shape first, then using the Shapes.AddPicture method to get a picture from the web.
I'll find that code and post it here.
Some more updates... The code "ActiveSheet.Pictures.Insert (path)" works fine in Excel 2007 at home. Strange it failed miserably on my work laptop. Do you think this has got something to do with SP2 of MS Office 2007 or something like that?
@Ian, Jon: Thanks for the code snippets. I guess I will use my home installation of excel to do this.
Chandoo:
Try this on your work laptop:
Sub test()
ActiveSheet.Shapes.AddShape msoShapeRectangle, 50, 50, 100, 200
ActiveSheet.Shapes(1).Fill.UserPicture _
"http://www.datapigtechnologies.com/images/dpwithPig6.png"
End Sub
FYI:
http://support.microsoft.com/kb/928983/en-us
I didn't mean to post code with a local file, because both approaches worked with an internet image as well. This is in Excel 2007 SP2.
activesheet.pictures.insert "http://peltiertech.com/images/2009-07/col_area_noblanks.png"
Jon: Looks like I have SP1 on my client machine! I wasn't paying attention.
Just checked my home computer where I have SP2, and you're right...looks like they fixed it.
I didn't even bother testing in SP1, though I could if anyone cares enough.
I'm afraid I don't have a solution, but I find it remarkable that after attaining a certain status in the Excel world, Chandoo does not need to post on an Excel discussion forum to get help for an Excel problem. Instead, he posts on his blog and all the gurus come rushing to his help.
Isn't Web 2.0 great?
Teylyn - I saw Chandoo's tweet first, and followed the link back to his blog.
@Mike.. thank you. I have seen the fill rectangle solution before posting the query here. For that matter, I have also tried the solution of embedding a browser control on a spreadsheet. both of these seemed a bit extreme. That is why I have asked it here.
But I guess I will end up using it if I had to build this in work laptop.
@Teylyn: I have thought of posting this in a forum. (Unfortunately I have not been to any excel group in the last 5 years. Last time I was active was when I built a jave based excel sheet construction solution using POI.HSSF classes of Apache... ) After searching for a few hours, I found several forum posts where others had same problem and the solution recommended (using .left and .top parameters) is not working for me. Incidentally most of these solutions are from a certain Jon Peltier 😛
I thought may be the problem is interesting for fellow blog readers. So I posted it here.
Hi,
Adapting the code in the question,
[code]
Sub InsPicture()
pPath = "http://chandoo.org/images/pointy-haired-dilbert-excel-charts-tips.png"
With ActiveSheet.Pictures.Insert(pPath)
.Left = Range("a1").Left
.Top = Range("a1").Top
End With
End Sub
[/code]
Seems to work fine
Looks like it was a problem in 2007 up to SP1, which was corrected in SP2.
@Jon.. seems like the case. I just checked the version at work laptop. it is 12.0.6331.5000 (SP1).
Thank you so much every one. I really appreciate your time and suggestions in solving this.
Glad to help. I couldn't understand why something so straightforward wasn't working.
Hi All
Is there a way of inserting a motion clip eg animated gif or swf or flv?
Thks
You can insert animated GIFs by inserting them in a browser control through VBA. For other types of movies, I can guess you can insert them as clip art.
I WANT THE INSERT PICTURE BY USING COADING
so currently i was struggling same as you, chandoo, with the insert picture method in excel 2007/10 from an url and came along your thread here.
so i re-designed the code on the addshape method as mike was suggesting it and all of the sudden it works just fine.
thanks alot to you guys, you were a great help
a big salut from switzerland
Hi guys,
I need help copying and pasting an image with the path in a cell.
I leave the code.
And thank you very much!
Sub Copiarimg()
Dim pic As Picture
With ActiveSheet
Set pic = .Pictures.Insert(Range("f2").Value)
With .Range("e9:g22")
pic.Top = .Top
pic.Left = .Left
pic.Width = .Width
pic.Height = .Height
End With
End Sub
I've played around with the approaches in these comments, and the code below is what I've come up with. The ImagePath can be a local file or a URL. As Jon mentioned above, the trick is to set an arbitrary value for the width and height, then call the ScaleWidth and ScaleHeight methods afterward to reset the picture to its original size. Once the LockAspectRatio property is set, you can change the picture width and the height will automatically scale (or vice-versa).
Sub AddPictureToRange(TopLeftCellAddress As String, ImagePath As String)
Dim pic As Shape
Dim l As Single, t As Single
Dim temp As Single
l = Me.Range(TopLeftCellAddress).Left
t = Me.Range(TopLeftCellAddress).Top
temp = 10# ' arbitrary value
Set pic = Me.Shapes.AddPicture(ImagePath, msoFalse, msoTrue, l, t, temp, temp)
pic.ScaleHeight 1#, msoTrue
pic.ScaleWidth 1#, msoTrue
pic.LockAspectRatio = msoTrue
End Sub
I need some help with inserting pictures. I have an excel file with a column of item numbers next to this row I want to insert a picture of this item. The pictures are coded with the item number so I tried to insert it with one of the codes above:
Sub InsPicture()
pPath = "http://img.bricklink.com/P/80/55236.gif"
With ActiveSheet.Pictures.Insert(pPath)
End With
End Sub
That worked but I need to do that for every row separtly.
So I tried in the code
pPath = "http://img.bricklink.com/P/80/"&Text(a1;"#")&".gif"
But that gives errors.
Anybody ideas?
Hi Nicholas, I used your solution in a related problem in Excel 2003 and it worked flawlessly..thank you!
Hi Mike Alexander,
Your solution with some changes was helpful in my problem in XL 2007, thanks.
Hi,
thanks all. In addition, I had a problem with multiple pictures inserting (every new picture replaced the prior one). I've changed it a bit, may be helpful..
Sub test()
ActiveSheet.Shapes.AddShape msoShapeRectangle, 50 , 50, 100, 200
ActiveSheet.Shapes(1).Fill.UserPicture _
"http://www.datapigtechnologies.com/images/dpwithPig6.png"
ActiveSheet.Shapes(1).Copy
ActiveSheet.Paste
End Sub
Try this instead:
Sub test()
ActiveSheet.Shapes.AddShape msoShapeRectangle, 50 , 50, 100, 200
ActiveSheet.Shapes(ActiveSheet.Shapes.Count).Fill.UserPicture _
"http://www.datapigtechnologies.com/images/dpwithPig6.png"
End Sub
Thanks to everyone, this thread has been very helpful. However, image inserting still doesn't work quite as expect for me.
While I can get a picture inserted into an Excel 2010 worksheet using either:
1) ActiveSheet.Shapes(ActiveSheet.Shapes.Count).Fill.UserPicture...
2) ActiveSheet.Pictures.Insert(pPath), and
3) Shapes.AddPicture...
unfortunately the images all insert with a display size determined not by the actual pixel dimensions of the image but by the dpi resolution.
So for example, if I insert two copies of the exact same 600x600 pixel image, one with a 300dpi resolution and the other with 72dpi, they display at vastly different sizes on screen.
While this might be intended behaviour for Excel in order to maintain a WSYWIG printing layout, I actually need a way to insert the image based on the the actual pixel dimesnsions and ignoring the dpi resolution.
Any help appreciated.
Thanks
Kez
Not doing an intentional bump, but realised I posted in rely to one of the repsonses here instead of to the main thread, so reposting.

Well, answered my own question 🙂
For those who might be interested, you can use this function:
Public Function GetPicDims(strFilePath As String, strFileName As String) As String
GetPicDims = CreateObject("Shell.Application").Namespace((strFilePath)). _
ParseName(strFileName).ExtendedProperty("Dimensions")
End Function
to get the dimensions of the image you want to insert. Then you can parse the return string and use the width and height values to add a rectangle shape of the appropraite size, like:
ActiveSheet.Shapes.AddShape msoShapeRectangle 50, 50, iWidth, iHeight
which you then fill with the picture:
ActiveSheet.Shapes(ActiveSheet.Shapes.Count).Fill.UserPicture "c:\temp\test.jpg"
This way the picture gets inserted using the pixel dimensions and the (print) resolution gets ignored.
If desired, the GetPicDims function can be made more generic to get other ExtendedProperties.

Kez
