Flag a line chart series if it is over another series - vba

I have 2 sheets with about 10-20 graphs per sheet. every graph is of the same format witht the same series names. one series is called "forecast spendings" and the other is called "spendings should-be." I need to flag the chart when the forecast spendings line goes over the spendings shout-be line. I was thinking making a red dot on the given point(s).
I tried using a bunch of tricks with conditional foratting by making other data tables and manipulating the values but with no success.
VBA will probably be the solution. I've never used VBA on charts though so im not sure how to procede. I've been doing sone research but i dont know how to modify codes in accordance to my needs due to my inexperience with charts.
I think comparind an array of the 2 series would be the answer. this would then have to loop for each chart and then loof for each sheet.
I found this code that seems useable to me but i dont understant what is being referenced. I'm guessing this is assuming that htere is only one chart wiht one serie:
Dim chartIterator As Integer, pointIterator As Integer, _
seriesArray() As Variant
For chartIterator = 1 To ActiveSheet.ChartObjects.Count
seriesArray = ActiveWorkbook.Sheets("Sheet1").ChartObjects(chartIterator). _
chart.SeriesCollection(1).Values
For pointIterator = 1 To UBound(seriesArray)
If seriesArray(pointIterator) >= 0 Then
ActiveWorkbook.Sheets("Sheet1").ChartObjects(chartIterator). _
chart.SeriesCollection(1).Points(pointIterator).Interior.Color = _
RGB(146, 208, 80)
Else
ActiveWorkbook.Sheets("Sheet1").ChartObjects(chartIterator). _
chart.SeriesCollection(1).Points(pointIterator).Interior.Color = _
RGB(255, 0, 0)
End If
Next pointIterator
Next chartIterator
Please explain your answer so i can understand it and repeat it.
Thank you in advance for your time!

This seemed to work fine for me.
Sub tester()
Dim co As ChartObject
For Each co In ActiveSheet.ChartObjects
CheckChart co.Chart
Next co
End Sub
Sub CheckChart(cht As Chart)
Dim s As Series, sForecast As Series, sShould As Series
Dim i As Long
'see if we can find the required series on this chart
For Each s In cht.SeriesCollection
Debug.Print s.Name
If s.Name = "forecast spendings" Then Set sForecast = s
If s.Name = "spendings should-be" Then Set sShould = s
Next s
'series located?
If sShould Is Nothing Or sForecast Is Nothing Then
MsgBox "required series not found!"
Else
'found the series, so compare the point values
'assumes same # of points in both lines
' and same start/end
For i = 1 To sShould.Points.Count
If sForecast.Values(i) > sShould.Values(i) Then
'label point
With sForecast.Points(i)
.HasDataLabel = True
.DataLabel.Position = xlLabelPositionAbove
.DataLabel.Text = "!!!"
.DataLabel.Characters.Font.Color = vbRed
End With
End If
Next i
End If
End Sub

VBA Excel: Different colors in one line diagram depending on value

I'm looking for a way to have three different colors in the same line chart of a diagram in Excel, depending on the values themselves or where they are from (from which sheet f.e).
Till now, I have the following code:
Sub ChangeColor()
Dim i As Integer
Dim IntRow As Integer
Dim r As Range
ActiveSheet.ChartObjects("Cash").Activate
ActiveChart.SeriesCollection(1).Select
IntRow = ActiveChart.ChartObjects("Cash").Count
For i = 2 To IntRow
Set r = Cells(2, i)
If r.Value < 3000 Then
Selection.Border.ColorIndex = 5
Else
Selection.Border.ColorIndex = 9
End If
Next
End Sub
However, the if statement is not considered and the color of the whole line changes only whenever I change the first ColorIndex. I have no idea, how to color parts of the line depending on the values in the underlying table.
Moreover, by defining IntRow as ActiveChart.ChartObjects("Cash").Count I'm not able to get the length of my array. This problem can be solved by manual counting and declaring IntRow as an Integer, however, the version above seems nicer (if that is possible of course).
I appreciate any help! Thank you.
Alexandra
You can read the values directly from the chart series:
Sub ChangeColor()
Dim cht As Chart, p As Point, s As Series
Dim i As Integer
Dim numPts As Long
'access the chart directly - no select/activate required
Set cht = ActiveSheet.ChartObjects("Cash").Chart
'reference the first series
Set s = cht.SeriesCollection(1)
'how many points in the first series?
numPts = s.Points.Count
'loop over the series points
For i = 1 To numPts
Set p = cht.SeriesCollection(1).Points(i)
p.Border.ColorIndex = IIf(s.Values(i) < 3000, 5, 9)
Next
End Sub

Naming the non-empty cells of a column as the previous column's values

So what I want is a button that when pressed will automatically name the right hand column cells the left hand column values, my code at the moment looks something like this,
Private Sub CommandButton1_Click()
Range("F3").Name = Range("E3")
Range("F4").Name = Range("E4")
Range("F5").Name = Range("E5")
Range("F6").Name = Range("E6")
End Sub
I'm new to using VBA and have looked around a little but couldn't find what I wanted to achieve. Just want a simple solution which can automatically do what my code already does without having to be specific about cell rows.
I imagine that there will be either a while or for loop to repeat over many rows and an if statement for the code not running if a cell is empty.
Basically I want the command to run something like below but don't quite know how to write it in excel VBA myself.
for j=3:100
if F(j) = non empty
F(j).name = E(j)
else end
next j
end
Image below shows the end result :
From your sample image this looks like it should work.
Option Explicit
Sub name_eff()
Dim rw As Long
With Worksheets("Sheet6")
For rw = 2 To Application.Min(.Cells(.Rows.Count, "E").End(xlUp).Row, _
.Cells(.Rows.Count, "F").End(xlUp).Row)
If Application.CountA(.Cells(rw, "E").Resize(1, 2)) = 2 Then _
.Cells(rw, "F").Name = .Cells(rw, "E").Text
Next rw
End With
End Sub

Referencing Multiple Sheets with large sets of Data

I am fairly new to VBA and having some general obstacles with basic syntax. I am using the below code to trim leading spaces and color code an ActiveSheet I am currently working on.
I have another Worksheet called "Country" that I would like to apply the same logic to the current sheet I am using. I am also having difficulties using the most efficient code to find any cells with values of "AcctTotal" , " CurrTotal" and " BravoTotal" (there are about 14,000 rows of data). I am currently highlighting the whole spreadsheet and utilizing "UsedRange" to find these cells.
To sum it up:
I would like to trim leading spaces and color code any values of "AcctTotal" , " CurrTotal" and " BravoTotal" in two worksheets: "Currency" and "Country"
Sub ColorCodeCurrency()
Dim r As Range
For Each r In Selection
If r.Value = " AcctTotal" Then
r.Value = LTrim(r.Value)
Intersect(r.EntireRow, ActiveSheet.UsedRange).Interior.ColorIndex = 15
End If
Next r
Dim s As Range
For Each s In Selection
If s.Value = " CurrTotal" Then
s.Value = LTrim(s.Value)
Intersect(s.EntireRow, ActiveSheet.UsedRange).Interior.ColorIndex = 40
End If
Next s
Dim t As Range
For Each t In Selection
If t.Value = " BravoTotal" Then
t.Value = LTrim(t.Value)
Intersect(t.EntireRow, ActiveSheet.UsedRange).Interior.ColorIndex = 35
End If
Next t
End Sub
Most of the problem is that you're doing the same thing three times. The 'For Each' statement is going through every cell three times. If you joined it into
for each r in selection
if r.value ="AcctTotal" then
'do something
elseif r.value = "CurrTotal" then
'do something else
elseif r.value = "BravoTotal" then
'do the third thing
end if
In addition to what Maudise said, when you refer to your data, you can use syntax like:
Sheets("Country").Range("A1:E14000")
If it's possible to make changes to your source data, you may find it helpful to format it as a table for easy reference. Use the Name Manager to give the table a useful name. Then, you can say something like:
For Each r In Sheets("Country").Range("CountryTable")
You could try this way:
Public Sub ColorCode ()
Dim i As Integer, j As Integer, m As Integer, n As Integer
i = Range("A:A").End(xlDown).Row
j = Cells.End(xlToRight).Column
For m = 1 To i
For n = 1 To j
If Cells(m, n).Value < 50 Then
Cells(m, n).Interior.ColorIndex = 13
End If
Next n
Next m
End Sub
One solution is to call this code placed in a module into "This workbook" in "Private Sub Workbook_Open()".

VBA code to hide a number of fixed discrete rows across a few worksheets

I'm for a solution to part of a macro I'm writing that will hide certain (fixed position) rows across a few different sheets. I currently have:
Sheets(Sheet1).Range("5:20").EntireRow.Hidden = True
To hide rows 5-20 in Sheet1. I also would like to hide (for arguements sake), row 6, row 21, and rows 35-38 in Sheet2 - I could do this by repeating the above line of code 3 more times; but am sure there's a better way of doing this, just as a learning exercise.
Any help much appreciated :)
Chris
Specify a Union of some ranges as follows
With Sheet1
Union(.Range("1:5"), .Rows(7), .Range("A10"), .Cells(12, 1)).EntireRow.Hidden = True
End With
Here is a try:
Sub hideMultiple()
Dim r As Range
Set r = Union(Range("A1"), Range("A3"))
r.EntireRow.Hidden = True
End Sub
But you cannot Union range from several worksheets, so you would have to loop over each worksheet argument.
This is a crude solution: no validation, no unhiding of existing hidden rows, no check that I have a sheet name as first parameter, etc. But it demonstrates a technique that I often find useful.
I load an array with a string of parameters relevant to my current problem and code a simple loop to implement them. Look up the sub and function declarations and read the section on ParamArrays for a variation on this approach.
Option Explicit
Sub HideColumns()
Dim InxPL As Integer
Dim ParamCrnt As String
Dim ParamList() As Variant
Dim SheetNameCrnt As String
ParamList = Array("Sheet1", 1, "5:6", "Sheet2", 9, "27:35")
SheetNameCrnt = ""
For InxPL = LBound(ParamList) To UBound(ParamList)
ParamCrnt = ParamList(InxPL)
If InStr(ParamCrnt, ":") <> 0 Then
' Row range
Sheets(SheetNameCrnt).Range(ParamCrnt).EntireRow.Hidden = True
ElseIf IsNumeric(ParamCrnt) Then
' Single Row
Sheets(SheetNameCrnt).Range(ParamCrnt & ":" & _
ParamCrnt).EntireRow.Hidden = True
Else
' Assume Sheet name
SheetNameCrnt = ParamCrnt
End If
Next
End Sub

Elegant way to highlight chart data series in Excel

I want to outline the chart data range source(s) in a table, in much the same way that the GUI will outline a range in blue if the chart data series is clicked. The user can choose various chart views and the range highlight colours for each data series need to match those displayed in the chart.
For the record, here are the methods I considered:
Parse the chart series values string and extract the data range
Do a lookup on a table that stores information on the ranges and the colours to be used
In the end I went with option 2 as is seemed easier to implement and to properly manage the colours I would probably have to store them for method 1 anyway, negating its benefits.
The highlight procedure is called from the Worksheet_Change event, a lookup is done on the chart name, the ranges and colours pulled from the table and then the cell formatting is carried out. The limitation of this method is that the range/colour data for each new chart view must be pre-calculated. This isn't much of a problem for my current implementation, but my be a limiting factor in future use where the charts might be more dynamic.
So although I've got a version of this working fine, I'm sure there must be a more elegant way of achieving this.
Any suggestions?
Edit:
OK, this seems to handle more cases better. The triggering code is the same, but here is new code for the module:
Function SeriesRange(s As Series) As Range
Dim sf As String, fa() As String
sf = s.Formula
sf = Replace(sf, "=SERIES(", "")
If sf = "" Then
Set SeriesRange = Nothing
Exit Function
End If
fa = Split(sf, ",")
Set SeriesRange = Range(fa(2))
End Function
Sub x(c As Chart)
Dim sc As Series
Dim sr As Range
If SeriesRange(c.SeriesCollection(1)) Is Nothing Then
Exit Sub
End If
Set sr = SeriesRange(c.SeriesCollection(1))
sr.CurrentRegion.Interior.ColorIndex = xlNone
For Each sc In c.SeriesCollection
If sc.Interior.Color > 1 Then
SeriesRange(sc).Interior.Color = sc.Interior.Color
ElseIf sc.Border.ColorIndex > 1 Then
SeriesRange(sc).Interior.Color = sc.Border.Color
ElseIf sc.MarkerBackgroundColorIndex > 1 And sc.MarkerBackgroundColorIndex < 57 Then
SeriesRange(sc).Interior.ColorIndex = sc.MarkerBackgroundColorIndex
ElseIf sc.MarkerForegroundColorIndex > 1 And sc.MarkerForegroundColorIndex < 57 Then
SeriesRange(sc).Interior.ColorIndex = sc.MarkerForegroundColorIndex
Else
MsgBox "Unable to determine chart color for data series " & sc.Name & " ." & vbCrLf _
& "It may help to assign a color rather than allowing AutoColor to assign one."
End If
Next sc
End Sub
/Edit
This is probably more barbaric than elegant, but I think it does what you want. It involves your first bullet point to get the range from the Series object, along with a sub to run through all the Series objects in the SeriesCollection for the chart. This is activated on Chart_DeActivate. Most of this code is jacked - see comments for sources.
In a module:
Function SeriesRange(s As Series) As Range
Dim sf As String, fa() As String
Dim i As Integer
Dim result As Range
sf = s.Formula
sf = Replace(sf, "=SERIES(", "")
fa = Split(sf, ",")
Set SeriesRange = Range(fa(2))
End Function
Sub x(c As Chart)
Dim sc As Series
Dim sr As Range
Set sr = SeriesRange(c.SeriesCollection(1))
sr.CurrentRegion.Interior.ColorIndex = xlNone
For Each sc In c.SeriesCollection
SeriesRange(sc).Interior.Color = sc.Interior.Color
Next sc
End Sub
In the ThisWorkbook object module:
' Jacked from C Pearson http://www.cpearson.com/excel/Events.aspx '
Public WithEvents CHT As Chart
Private Sub CHT_Deactivate()
x CHT
End Sub
Private Sub Workbook_Open()
Set CHT = Worksheets(1).ChartObjects(1).Chart
End Sub
Have you tried using Conditional Formatting?
