I've formatted the markers of a chart using VBA:
Dim sc As SeriesCollection
Set sc = MySheet.ChartObjects("MyChart").Chart.SeriesCollection
Dim p As Point, s As Series
For Each s In sc
For Each p In s.Points
p.Format.Fill.ForeColor.RGB = s.Format.Line.ForeColor.RGB
p.Format.Fill.BackColor.RGB = s.Format.Line.ForeColor.RGB
p.MarkerSize = 3
Next p
Next s
However, the markers in the chart area don't match up with the markers in the legend (the border colour is the same, but the fill colour in the legend is different). Note the colour inside the boxes on the right (the legend):
I've looked around at a few different properties of the Chart family, but can't find what controls this. The Point properties MarkerBackgroundColor and MarkerForegroundColor seemed likely, but don't fix it. How can I fix this?
Since you were looping the seriescollection, you could simply do all the markers in one go:
For Each s In sc
s.MarkerBackgroundColor = s.Border.Color
s.MarkerSize = 3
Next s
Found with a bit more digging:
Worksheet.ChartObjects(Index).Chart.Item(Index).Format.Fill.ForeColor.RGB
Pretty lengthy!

I have a x,y scatter chart with lines connecting the dots from one source. I have between 1 and 8 lines and I need to have the MarkerStyle assigned to each line. Since the lines are not fixed and depend on the current data, I can't say which lines are there.
In general I could just assign
ActiveChart.FullSeriesCollection(i).MarkerStyle = xlMarkerStyleAutomatic
But that also assigns unwanted/unreadable Markers. So could I create a Collection with the Markerstyles I want and than assign that?
I tested
Dim colMarker As Collection
Set colMarker = New Collection
colMarker.Add "xlMarkerStyleCircle"
colMarker.Add "xlMarkerStyleSquare"
colMarker.Add "xlMarkerStyleTriangle"
With ActiveChart.FullSeriesCollection(i)
.MarkerStyle = colMarker(1)
End With
But the error msg is wrong type
What type do I need?
Thanks Kaz
You can set the marker style for each series individually:
Dim s as Series
s = ActiveChart.SeriesCollection.NewSeries
s.MarkerStyle = xlMarkerStyleCircle
Edit:
To assign different marker styles use the approach you suggested, but when adding styles to the collection it should be done like this:
colMarker.Add xlMarkerStyleDiamond
etc, ie without quotation marks.
I am trying to add data labels to all my series in a bar chart but the amount of series varies from chart to chart because this is a function used for many charts. So, I used a For Loop to add them, but I need to determine the size of the SeriesCollection array. Would there be a function that would do so? When I try to use .Size it gives me an error.
Below is what I tried:
With Chart
For i = 1 To .SeriesCollection.Size
.SeriesCollection(i).Points(i).HasDataLabel = True
Next i
End With
Some of the stuff in the Chart object model isn't properly hooked up to Intellisense. You'll notice that you get no suggestions when you type .SeriesCollection.
.SeriesCollection.Count will give you what you're after, I think.
Well I am trying to change the colors for my graph based on label conditions.
First of all, this is how the graph looks like.
I was trying to change the values based on three conditions. Warning, Critical and Emergency. Basically having three different colors for each of the conditions. For example all Emergencies be red, all critical be orange and all warning be yellow. "Title" is x-axis in my case and "criticality" happens to be the cluster.
I tried following the thread
excel vba changing bar chart color for a data point based on point value
I also looked at this thread Changing Bar colors using VBA based on category label
I havent had any luck trying to use the code from both the threads.
This code from the second thread actually made sense for me to use in my case.
Dim c As Chart
Dim s As Series
Dim iPoint As Long
Dim nPoint As Long
Set c = ActiveChart
Set s = c.SeriesCollection(1)
nPoint = s.Points.Count
For iPoint = 1 To nPoint
If s.XValues(iPoint) = "avg" Then
s.Points(iPoint).Interior.Color = RGB(255, 0, 0)
End If
Next iPoint
But not sure what variables should I be changing. Any help is welcomed!
Thanks.
the s.XValues(iPoint) will contain Title and Criticality concatenated.
Try to change:
If s.XValues(iPoint) = "avg"
to:
If right(s.XValues(iPoint), 9) = "Emergency"
In this way you will check if the last 9 letters of the label are exactly "Emergency".
You should be able to modify your code to add another condition for Critical or Warning.
Hope this help,
The Macro Guru
I was wondering how to attach a textbox to a point or line in an Excel chart for the macro I am working on. I have been using the .AddTextbox method such as
.Shapes.AddTextbox(msoTextOrientationHorizontal, 150, 250, 100, 15) _
.TextFrame.Characters.Text = "Temperature"
But I have to then manually drag the textbox over the line on the chart it is representing as the orientation is of the chart not the line. Is there a way to convert the line/point to a chart orientation which I could use as a variable? or another way? Possibly using the datalabel function, though I want to be able to customize one of the axis locations. Thanks
To solve your question you need to get the left & top position of two objects:
chart itself, which position is set in relation to top-left corner of sheet range area
point in series which position is set in relation to top-left corner of chart
Combination of both result with the following code (fixed parameters-required changes to your situation, could be more dynamic with loop)
Sub Add_Text_to_point()
Dim tmpCHR As ChartObject
Set tmpCHR = Sheet1.ChartObjects(1) 'put index of your chartobject here
'for first serie, for point 2nd here
'(change accordingly to what you need)
With tmpCHR.Chart.SeriesCollection(1).Points(2)
Sheet1.Shapes.AddTextbox(msoTextOrientationHorizontal, _
.Left + tmpCHR.Left, _
.Top + tmpCHR.Top, _
100, 15) _
.TextFrame.Characters.Text = "Temperature"
End With
End Sub
After result presenting the picture below.
Another option would be to use the data labels of Excel. I see two more elegant options:
Make a new data series with just one entry in your chart, give the series the coordinates and the name of the label you want to see. Now activate the marker option for the series (if not done already), right-click on the data point, click "add data labels". Now you'll see the y-Value of the point. By right-clicking again and choosing "Format Data Labels" you can change the text to the series name, also the position, the border, etc. are modifiable. Below an example with two data points. You could delete the second point, the line and the marker but like this you see how it works.
Similarly to the solution from KazJaw you can use the actual data points of your series for attaching custom data labels. This requires some coding, I used this for the chart named "Topview" and wrote percentages next to the data point
Sub Add_Text_to_data_points()
percentages(1) = 0.1
percentages(2) = 0.23
'.... further entries
chartNumber = findChartNumber("Topview")
collNumber = 12 ' index of the "points" series
Set tmpCHR = ActiveSheet.ChartObjects(chartNumber)
For i = 1 To tmpCHR.Chart.SeriesCollection(collNumber).Points.count
With tmpCHR.Chart.SeriesCollection(collNumber).Points(i)
If percentages(i) <> 0 Then
.DataLabel.Text = format(percentages(i), "0%")
End If
End With
Next
End Sub
I'm trying to automate a process that so far I have been doing manually in Excel 2010. I create Pivot Charts often. One of the series on these charts is displayed as bars. I change the fill color of each bar based on one of the row labels of the pivot chart. For instance, if the row label = "GEO", I change the fill color of the bar to green.
I'm sure that it's possible to automate this process through VBA. Here's my code so far. When I run this macro, it stops at the first line of the If statement and gives this error. Compile error: Expected array. Can anyone give me some advice as to how to make this code work?
Sub By_Rig_PC_Coloring()
For i = 1 To ActiveChart.SeriesCollection(2).Points.Count
ActiveChart.SeriesCollection(2).Points(i).Select
If xlRowField("MFR") = "GEO" Then
Selection.Format.Fill.Forcolor.RGB = RGB(0, 176, 80)
End If
Next i
End Sub
As far as I know, you cannot access X axis labels associated with current Point. But this is a PIVOT chart, so you can use your pivot table to get the info you need.
Points are DataField's PivotItems, Series are ColumnFields and X labels are RowFields.
So SeriesCollection(2).Points(10) will be pvtYourPivotTable.ColumnFields(2).DataRange.Cells(10) (assuming that you have only one DataField, otherwise DataRange will be multi-column, and you'll have to adjust for that).
So once you have a cell in pivot table assosacietd with Point, the label will be located at Intersect(pvtYourPivotTable.RowFields("MFR").DataRange, pvtYourPivotTable.ColumnFields(2).DataRange.Cells(10).EntireRow. You can also use Offset or other method.
Here is another method of colouring chart bars based on X labels: Peltier Tech Blog without VBA.
Hope this helps.
