Im using actxserver to write data to an excel sheet and to format it. I managed to color cells and to add frames to the cells, but I am stuck at adding databars.
The corresponding VBA code would be:
Range("D7:D217").Select
Selection.FormatConditions.AddDatabar
Selection.FormatConditions(Selection.FormatConditions.Count).ShowValue = True
Selection.FormatConditions(Selection.FormatConditions.Count).SetFirstPriority
With Selection.FormatConditions(1)
.MinPoint.Modify newtype:=xlConditionValueAutomaticMin
.MaxPoint.Modify newtype:=xlConditionValueAutomaticMax
End With
With Selection.FormatConditions(1).BarColor
.Color = 13012579
.TintAndShade = 0
End With
Selection.FormatConditions(1).BarFillType = xlDataBarFillSolid
Selection.FormatConditions(1).Direction = xlContext
Selection.FormatConditions(1).NegativeBarFormat.ColorType = xlDataBarColor
Selection.FormatConditions(1).BarBorder.Type = xlDataBarBorderNone
Selection.FormatConditions(1).AxisPosition = xlDataBarAxisAutomatic
With Selection.FormatConditions(1).AxisColor
.Color = 0
.TintAndShade = 0
End With
With Selection.FormatConditions(1).NegativeBarFormat.Color
.Color = 255
.TintAndShade = 0
End With
How can I change the code to make it work in Matlab? Any advice, also a link to general advice on how to use actxserver with Excel (i.e. what changes to the VBA code need to be done) is appreciated. Thanks!

Since you have a working VBA script, you can create a macro with your code. You can then run an excel macro from MATLAB using the instructions in the below MATLAB answers page:

Thank you for your answer! I found my way around it by formatting an empty excel sheet and copying it into the used one every time the program is used. But your way would work as well especially with more complicated topics.

If someone ever gets the same problem, I found the solution myself, using the invoke command. Excel is openend in Actxserver.
dummy_range = 'A1:A100';
Excel.Range(dummy_range).Select;
Databar = invoke(Excel.Selection.FormatCondition, 'AddDatabar');
Databar.BarFillType = 'xlDataBarFillSolid';
Databar.AxisPosition = 'xlDataBarAxisAutomatic';
Databar.BarColor.ThemeColor = 5;
Databar.NegativeBarFormat.ColorType = 'xlDataBarSameAsPositive';
Once you know how to do it, it gets quite self explanatory.
