How to calculate an average using VBA - excel

I am getting the following error
My code below
GrossMean = WorksheetFunction.Average("AK21:AK100020")
sheet1.Cells(4, 44) = GrossMean

Define the range and in which worksheet it is as:
GrossMean = WorksheetFunction.Average(ThisWorkbook.Worksheets("Sheet1").Range("AK21:AK100020"))
And make sure that there is numeric data in that range. If it is empty you get the same error.

Excel VBA graph based on Series not working properly

I'm using the following VBA code in Excel in order to produce 2 graphs with a data picked up from the sheet and slightly elaborated. As I'm not using ranges directly for the graphs and need to use arrays for X and Y axes, I decided to go for Series. X has Date type and Y has Integer type. First it worked, but then the graphs started giving me wrong data, something random coming directly off the sheet. I suppose there could be something wrong in the way how the charts are declared. Here's the code, what could go wrong with it?
Dim crt1, crt2 As Chart
Dim sr1, sr2 As Series
ActiveSheet.Shapes.AddChart2(201, xlColumnClustered, 60, 50).Select
Set crt1 = ActiveChart
Set s1 = crt1.SeriesCollection.NewSeries()
sr1.Values = dataArray1
sr1.XValues = datesArray1
ActiveSheet.Shapes.AddChart2(332, xlLineMarkers).Select
Set crt2 = ActiveChart
Set s2 = crt2.SeriesCollection.NewSeries()
sr2.Values = dataArray2
sr2.XValues = datesArray2
This problem also persists when I comment the code for the second graph.
P.S. Excel says "Runtime error 424. Object required" underlining "sr1.Values = dataArray1" and then "sr1.XValues = datesArray1"

Using MATLAB to write String values into Excel spreadsheet via ActiveX protocol.. found a problem

I'm using MATLAB 2017a and have been using xlswrite in the past to perform this operation. The problem I ran into was with execution speed and I was looking for a better way. So, I decided to use actxserver and write data using get(obj) from MATLAB and Range.Value from ActiveX. Here's what the code looks like:
e = actxserver('Excel.Application);
eWorkbook = e.Workbooks.Add;
e.Visible = 1;
eSheets = e.ActiveWorkbook.Sheets;
eSheet1 = eSheets.get('Item',1);
eSheet1.Activate;
A = ["Str1";"Str2";"Str3";];
eActivesheetRange = get(e.Activesheet, 'Range', 'A1:A3');
eActivesheetRange.Value = A;
This inocuous bit of code does not execute, nor does it throw a warning or error message.. Nothin'. In my mind, the eActivesheetRange evaluates to: Range("A1:A3") on the ActiveX side. Interestingly, if I replace
A = ["Str1";"Str2";"Str3";];
with
A = char(["Str1";"Str2";"Str3";]);
then the program writes the A char array to each cell in the eActivesheetRange Range.
Is there a way to call cells() using the MATLAB Range.Value connection? Would cells().Value be able to solve this problem?
I don't think writing to Excel using ActiveX is able to handle string types properly. In this case, you can make it work by simply converting your string array into a cell array of character vectors using cellstr. Changing your last line of code to the following works for me (in R2016b):
eActivesheetRange.Value = cellstr(A);
Replacing the last two lines with the following also works:
e.Activesheet.Range('A1:A3').Value = cellstr(A);
The solution to this is of course, a for loop.
alphacolumn=char(97:117);
% iterate through data array
for i=1:21
str=string(alphacolumn(i))+2;
str2=string(alphacolumn(i))+202;
write1=char(str+":"+str2);
if ~isreal(tsc{i,1})
T = (tsc{i,1});
for j = 1:length(T)
rrange = xl.ActiveWorkbook.Activesheet.Range(char(string(alphacolumn(i)) + string(j+1)));
xlcompatiblestring1 = char(string(T(j,:,:)));
rrange.Value= xlcompatiblestring1;
end
else
tsci=tsc{i,1};
% write data to xl target file
%xlswrite(xlfilepath,tsci,write1);
xlActivesheetRange = get(xl.Activesheet,'Range',write1);
xlActivesheetRange.Value = tsci;
end
end

Excel VBA - Get chart data range

I want to add data to a bunch of existing charts. Assume that each chart has a different number of data series and that the location of the raw data is somewhere in the same workbook. Here's what I'm starting with:
For iChart = 1 To iCount
ActiveSheet.ChartObjects("Chart " & iChart).Activate
intSeries = 1
Do Until ActiveChart.SeriesCollection(intSeries).Name = ""
Set rXVal = ActiveChart.SeriesCollection(intSeries).XValues '<- Object Required error
Set rXVal = Range(rXVal, rXVal.End(xlDown))
Set rYVal = ActiveChart.SeriesCollection(intSeries).Values
Set rYVal = Range(rYVal, rYVal.End(xlDown))
ActiveChart.SeriesCollection(intSeries).XValues = rXVal
ActiveChart.SeriesCollection(intSeries).Values = rYVal
intSeries = intSeries + 1
Loop
Next iChart
I know that ActiveChart...XValues = rXVal works, but I'm getting an "Object Required" error on the Set rXVal = ActiveChart....XValues line. I'm assuming that since a range went in to define the data series, I can get that range back out again and then add to it.
UPDATE
To clarify things a little, I have accelerometers in 8 places and FFT software setup to record peak vibration response in 4 separate frequency bands. This yields 32 data points per sample. When exporting, the software spits out an Excel workbook with 4 sheets; one for each frequency band. Each sheet has the accelerometer names going across and sample numbers going down.
I have succeeded using this syntax:
Dim rXVal() As Variant
rXVal = ActiveChart.SeriesCollection(intSeries).XValues
UPDATE
In this case you get an array, because your given statement (ActiveChart.SeriesCollection(intSeries).XValues) is an array and not a range. This is what you see in Locals window if you dig into Series object of ActiveChart.SeriesCollection(intSeries):
(in my dummy data I have rows named r1, r2, r3, r4.)
What I want to say, XValues does not have any property which would indicate its occupied range.
If you actually need a range, I would suggest getting it from the formula property. And the way I would suggest is replacing your error causing line with this one:
Set rXVal = Range(Split(ActiveChart.SeriesCollection(intSeries).Formula, ",")(1))
Next, I see you trying to get the range for Values. Similarly, use this:
Set rYVal = Range(Split(ActiveChart.SeriesCollection(intSeries).Formula, ",")(2))
Another thing.
The following lines will cause you an error finally:
intSeries = 1
Do Until ActiveChart.SeriesCollection(intSeries).Name = ""
...some code...
intSeries = intSeries + 1
Loop
Do change them with:
For intSeries = 1 To ActiveChart.SeriesCollection.Count
...some code...
Next
Yet another thing.
Consider using With and End With, as you repeat a lot ActiveChart.SeriesCollection(intSeries). Then your code will be much more readable, as you would just skip this long line! Wouldn't that be awesome???
This works fine for me:
Dim rXVal() As Variant
Dim rXValMin, rXValMax As Double
rXVal = ActiveChart.SeriesCollection(intSeries).XValues
rXValMin = WorksheetFunction.Min(rXVal)
rXValMax = WorksheetFunction.Max(rXVal)

Pivot Tables - VBA

I want to select some values through VBA in Pivot Table which is linked to OLAP Cube.
As I know such modification can be realised by typing:
ActiveSheet.PivotTables("PivotTable1").PivotFields("[parameter].[parameter]").VisibleItemsList = Array("value1","value2","value3")
Since get list of parameters from cells in Excel sheet, I wrote simple function which - In mentioned example - returns:
""value1","value2","value3""
I can't use such string as parameter for Array function (as it recognize it as one string), so I've tried to convert it to Array of Variant, typing above code:
Dim tableVar() As Variant
myVar = Replace(myVar, Chr(34), "")
myVar = Split(myVar, ",")
lowerB =LBound(myVar)
upperB = UBound(myVar)
ReDim tablica(lowerB To upperB)
For i = lowerB To upperB
tableVar(i) = myVar(i)
Next i
Unfortunately it changes nothing - when I'm calling:
ActiveSheet.PivotTables("PivotTable1").PivotFields("[parameter].[parameter]").VisibleItemsList = tableVar
I'm still receiving an error message.
Could you help me, please?
you have a typo in your code, daty should say myVar.
(Either that or we're missing more details)
Stupid thing, but error message is simply correct - there's no such items in Cube:
Run-time error '1004': The item could not be found in the OLAP Cube
I gave incorrect parameter here:
ActiveSheet.PivotTables("PivotTable1").PivotFields("[parameter].[parameter]").VisibleItemsList = tableVar
My code was unnecessary complicated - sorry for wasting your time.
Now my problem will be - how to check if specific dimensions or whole Cube exist...
Thanks once more for help.

Excel 2010 index match VBA

Tried everything and can't seem to get this. Trying to replace values in Row B (SiteTag) of one worksheet with the proper sitetag from an index match in another worksheet.
Worksheet(Site_Visit)
SiteTag
AL27
AS26
GBEM4
...
Worksheet(Sites)
SiteTag Project Name
203AL27 AL27
203AS26 AS26
201GBEM4 GBEM4
... ...
I need to replace the values SiteTag in Sheets("Site_Visit") with the appropriate SiteTag from Sheets("Sites").
For now I've simply tried to get the code to place the correct index value into a variable in which I'll place as the value for each cell, and run it in a loop. But for the life of me can't get it to get a value. This is what I've tried for the variable (everything has been declared).
ST_Cells2 = Application.WorksheetFunction.Index("Sites!A2:A34", Application.WorksheetFunction.Match("Site_Visit!B2", "Sites!B2:B34", 0), 0)
Where "Sites!A2:A34" is the range for the appropriate replacement value
"Sites_Visit!B2" is the lookup value
"Sites!B2:B34" is the lookup range
I'm getting a Run Time error '1004' Unable to get the Match property of the WroksheetFunction class. Anyone have any ideas?
The Index and Match functions are expecting Ranges, but you are sending them strings. The easiest way to turn strings into Ranges is to use Excel's Range function:
st_cells2 = Application.WorksheetFunction.Index(Range("Sites!A2:A34"), Application.WorksheetFunction.Match(Range("Site_Visit!B2"), Range("Sites!B2:B34"), 0), 0)
I had the same error, but it run ok when I changed to "Application" indstead of WorksheetFunction:
Cells(12, 12).Value = Application.Index("Sheet1!B1:9", 2)
Somehow running the Function from Application directly worked...
