Why does changing Chart LINE properties in VBA do not work? - vba

I copy-pasted an embedded chart into a new worksheet. I was able to change the source data but could not change the line weight and the color. I don't understand what is happening... great to get feedback! Here is my code:
With .SeriesCollection(1)
.Values = DP.Sheets("Sheet1").Range("A18:A58")
.XValues = DP.Sheets("Sheet1").Range("C18:C58")
.Format.Line.Weight = 1
.Format.Line.ForeColor.RGB = RGB(0, 0, 0)
End With
SeriesCollection(1) has existing links which is replaced by those references/ranges. This changes the line color to 'AUTOMATIC' and excel assigns a very odd color which I want to change back to black. Unsure with what is happening. Help please!

Any codes that does clear color completely for powerpoint shape?

'I have tried to apply a color by vba with this code to a shape
.Fill.ForeCorlor.RGB = RGB(250, 0, 0)
'but soon I realize this color stay in memory* even though I tried to clear it with
.Fill.Transparency = 0.5 'Or
.Fill.Visible = msoFalse
'I do not want to use .Fill.ForeColor.TGB = RBB(255, 255, 255)
to set another color as it may overlay and block other content
*In memory: I mean when I applied a color to a shape and try to clear it with the above method, The next time I target shape with RGB(230,0,0), this shape that I thought has been previously set the color and clear still get targeted.
Appreciate for any help on this

Excel - Fill a cell with different colors

I need to fill a cell with different colors as in this picture (3 rows are merged vertically and colors are drawn manually in this picture using 3 rectangular shapes):
The only way I could find to fill part of a cell is using conditional formatting (by setting style as data bar and fill as solid) but it support only one color.
Is this possible with or without VBA?
It is possible.
I have found two ways to do that.
1- Using a black square shaped character (character code 2588 – vba: ActiveSheet.Cells(1, 1) = ChrW(&H2588)) and color them according to percentage. This character fills the cell height and also there is no spacing between them which allows filling a cell completely (Sure you should consider left indent in a cell). Only issue here that you cannot use a lot of characters in one cell; I use 30 of them and scale the number of characters according to 30 (ie. 50% red means 15 red character-2588).
2- It is same as what #Doktor Oswaldo has suggested: Inserting a plot in a cell using cell's position and size in pixels. This method has one big advantage: you can show the ratios exactly. In addition, you can fill a data series with a pattern as well. However if you have a lot of plots, you will sacrifice from Excel performance. For plot settings, I use following VBA code:
'Define var's
Dim src As Range, targetCell As Range
Dim chacha As ChartObject
'Set var's
Set src = Worksheets("Sheet1").Range("B1:B3")
Set targetCell = Worksheets("Sheet1").Range("C2")
'Create plot at the target cell
Set chacha = Sheets("Sheet1").ChartObjects.Add(targetCell.Left, targetCell.Top, targetCell.Width, targetCell.Height)
'Change plot settings to fill the cell
With chacha.Chart
.ChartType = xlBarStacked
.SetSourceData Source:=src, PlotBy:=xlRows
.Axes(xlValue).MinimumScale = 0
.Axes(xlValue).MaximumScale = 100
.Axes(xlCategory).Delete
.Axes(xlValue).Delete
.Legend.Delete
.PlotArea.Top = -50
.PlotArea.Left = -50
.PlotArea.Width = targetCell.Width
.PlotArea.Height = targetCell.Height
.ChartGroups(1).GapWidth = 0
End With
chacha.Chart.SeriesCollection(1).Format.Fill.ForeColor.RGB = RGB(255, 0, 0)
chacha.Chart.SeriesCollection(2).Format.Fill.ForeColor.RGB = RGB(0, 0, 255)
chacha.Chart.SeriesCollection(3).Format.Fill.ForeColor.RGB = RGB(255, 255, 0)
In the code I modified the series colors manually which can also be automatized. Following is the screenshot of both methods. The Cell "C1" is filled with block characters and "C2" is a chart.
Note: You might get an error at the line ".PlotArea.Top". To solve this issue, please check: Error setting PlotArea.Width in Excel, VBA (Excel 2010)

VBA: set gradient fill background angle

I have the following problem: I want to set a chart background with "Gradient Fill" and change the angle with a macro.
Recording a Macro does not help. The only thing I got is the following:
With Selection.Format.Fill
.Visible = msoTrue
.ForeColor.RGB = RGB(255, 117, 117)
.BackColor.RGB = RGB(0, 203, 92)
.TwoColorGradient msoGradientDiagonalUp, 1
End With
In reality I want to set the colors in advance and use the macro just for orientation. The only thing the macro should do is:
If variable = A then 'select the chart and set angle to 45%
If variable = B then 'select the chart and set the angle to 135%
and so on.
I do not want to set manually the colors because I will have 4 colors and it useless to set them every time since their relative position is always the same within the gradient pattern.
Any Idea?
Ok, I made it.
It is very simple, but you cannot easily find this info online.
You need to activate your chart and after:
ActiveChart.PlotArea.Format.Fill.GradientAngle = 45

PowerPoint 2007/2010 VBA code to change Type of Gradient Fill on a Shape object

With PowerPoint 2007 & 2010, I have been trying to change the Type of Gradient Fill on a Shape object from default "Rectangular" to "Path" for days. Searched online but seems like no such question asked.
So far I can only get the Gradient Fill to be "Rectangle" (the default with 2 color gradient?). But I want it to be "Path". So far only able to do that by right click on the actual Shape --> Format Shape. "Format Shape" form shows and I can change the "Type:" from Rectangle to Path. But I want to do this change in VBA, anyone have a solution?
My code below. Variables starting with g are As Single
Set oSlide = ActivePresentation.Windows(1).View.Slide
With oSlide.Shapes.AddShape(msoShapeIsoscelesTriangle, gLeft, gTop, gWidth, gHeight)
.Line.Visible = msoFalse ' No Outline
.Adjustments(1) = gAdj1 ' Adjust the position of the pointing tip
.Rotation = gAngle ' Change the angle of Rotation
.Fill.Visible = msoTrue
.Fill.TwoColorGradient msoGradientFromCenter, 1 ' Enable Two Colour Gradient
.Fill.GradientStops(1).Color.RGB = RGB(255,255,255) ' Colour at center
.Fill.GradientStops(2).Color.RGB = RGB(121,121,121) ' Colour at edge
.Select
End With
Set oSlide = Nothing
If no VBA codes can achieve that, I will have to use workaround... Copy and Paste those Shapes from a Template file - this sounds bad as I am going to make it a PowerPoint AddIn.
Thanks in advance!

Arrow To Indicate Special Points Using VBA

I have seen some examples which uses an Arrow to Indicate Special Points on Excel chart like this. But i want to achieve this using VBA. For example if some point on chart is greater then 90 then it shows an arrow corresponding to that point.
Please suggest on how should I go about it in VBA. Any help would be appreciated.
Update
Apart from just changing the point color is there any other good suggestion to make that point more prominent. Update 2
Right now i am using this code.
For Each oCell In Range("e4:e" & LastRow) 'loop
If oCell.Value < sd13 Then 'rule 13s
Range("V4").Value = "Rule 13s voilated!"
Range("V4:w4").Interior.Color = RGB(255, 0, 0)
ActiveWorkbook.Sheets("LDL-C").ChartObjects("Chart 1047").Chart.SeriesCollection(1).Points(j).MarkerBackgroundColor = RGB(255, 0, 0)
End If
Next
Apart from just changing the point color is there any other good suggestion to make that point more prominent.
Would this help?
With ActiveChart
For i = 1 To .SeriesCollection.Count
a = .SeriesCollection(i).Values
For l = 1 To .SeriesCollection(i).Points.Count
If mymax < a(l) Then
mymax = a(l)
.SeriesCollection(i).DataLabels.Select
Selection.Format.Line.Visible = msoTrue
Selection.Format.Line.Visible = msoFalse
.SeriesCollection(i).Points(l).DataLabel.Select
.SeriesCollection(i).Points(l).Select
.SeriesCollection(i).DataLabels.Select
.SeriesCollection(i).Points(l).DataLabel.Select
With Selection.Format.Line
.Visible = msoTrue
.ForeColor.ObjectThemeColor = msoThemeColorAccent1
.ForeColor.TintAndShade = 0
.ForeColor.Brightness = 0
End With
With Selection.Format.Line
.Visible = msoTrue
.Weight = 2
End With
End If
Next l
Next
End With
SNAPSHOT
Another snapshot
Not sure how to do it with an arrow but here is a way to just change the colour of the point of interest:
With ActiveSheet.ChartObjects(ChartName).Chart.SeriesCollection("NCDs")
For currentPoint = 1 To .Points.Count
If Range("G" & currentPoint + 34).Value = True Then
With .Points(currentPoint).Format
.Fill.BackColor.RGB = RGB(50, 150, 50)
.Fill.ForeColor.RGB = RGB(50, 150, 50)
.Line.ForeColor.RGB = RGB(50, 150, 50)
End With
Else
With .Points(currentPoint).Format
.Fill.BackColor.RGB = RGB(150, 50, 50)
.Fill.ForeColor.RGB = RGB(150, 50, 50)
.Line.ForeColor.RGB = RGB(150, 50, 50)
End With
End If
Next currentPoint
End With
Just change the names and the condition clause...
Also maybe the .Points(currentPoint) object has x,y location properties which you could use to position your arrow. Not sure about that though but it seems like a good starting point.
Yeah, gotta have VBA. Problem with VBA is that someone has to remember to run the procedure, or set up a Worksheet_Calculate event, or whatever, so when the data changes, which it inevitably does, the chart keeps up with the data.
So here's my non-VBA approach, which relies on Excel formulas.
Simple data, supplied by Siddharth in his answer. I've added a column, which I call MAX. The formula in cell C2, copied down to C11, is
=IF(B2=MAX(B$2:B$11),B2,NA())
The first chart plots the regular series of data in a clustered column chart. The second chart has MAX added to it. In the third chart I've changed the Overlap to 100%, so the blue bar covers the corresponding gray bar. Next chart I've added data labels to the MAX series. In the last chart I've formatted the data label to show series name, and the font color =matches the bar color.
So here is the original data and chart (upper) and changed data with changed chart (below). The formulas did it all, no need to somehow rerun the VBA.
What's cool is if I have a tie for first place, I get two labeled blue bars, with no extra effort.
Not a big stretch to add a third series to indicate the MIN.
ActiveChart.FullSeriesCollection(1).Select
With Selection
.MarkerStyle = 8
.MarkerSize = 5
End With
Selection.MarkerStyle = 2
ActiveChart.ChartArea.Select
With Selection.Format.Line
