Don’t even add the bar chart series with the alpha-beta-gamma labels. Instead of these bars, you will need to build a set of secondary X and Y axes that will work with the XY series. The X axis will have the same scale as the Y (horizontal) axis of the bar chart, and the Y axis will simply scale from 0 to 1.

You need to change the data range for the axis series:

G1:I1 – keep category labels
G2:I2 – fill with zero values
G3:I3 – insert a fraction corresponding to the height of the label**

**For example, “alpha” is the third label from the bottom (let i=3), and there are a total of 3 labels (N=3). The fraction is

(i-0.5)/N

So the fractions for alpha, beta, and gamma are 0.83333, 0.5, and 0.16667.

Clear F2 and put the “axis” label into F3.

Copy F2:I3, select the chart, paste special to add the data as a new series, data in rows, categories in first row, series names in first column. It is added as a bar chart series, but when you change it to an XY type, Excel adds the secondary X and Y axes, and you need to rescale tham as I’ve described above. Repeat the copy-paste special with the data to add the target line as described in Add a Vertical Line to a Column or Line Chart: Series Method or in Add a Vertical Line to a Column or Line Chart: Error Bar Method.

Following up on your comment to Chris above, I was unsuccessful in getting the “target line” to add to a Clustered-Stacked Bar chart. I get the “Some chart types cannot be combined with other types. Select a different chart type” error, and all hell breaks loose when I try to remove the dummy axis series. I’ve always (not just this time) had some trouble with adding those extra series of XY points, so this may just be another instance of that problem, but it seems like this is something non-trivial to be done here…

Thanks for any suggestions-

But I slightly changed the text.
I modified the text using
Alpha = Alpha & vbCrLf & 10
With this, the tick table text is displayed as
Alpha
  10
But I wanted to show it as
Alpha
   10

Any ideas?

Two points:
1. The labels are already right-aligned, aren’t they?
2. I recall puzzling over why this alignment property didn’t have any effect anyway.

Is it possible to align the Category axis TickLabels such as xlRight ?

I tried with the code
ActiveChart.Axes(xlCategory).Select
Selection.TickLabels.AutoScaleFont = True
With Selection.TickLabels
.Alignment = xlRight
.Offset = 0
.ReadingOrder = xlRTL
.Orientation = xlHorizontal
End With

but it is not working.

Please tell how to do that?

But I needed to show them to the user. So, I used that method

This works the same as using B, C, D, etc., which I used in the example. The labels are hidden finally, so exactly what they say does not matter.

Give another range for secondary axis label, that will take care of the rest.

For the above example, the range has to be(put one in each cell)
Alpha Alpha Alpha Beta Beta Beta Gamma Gamma Gamma

Thanks for your time
