I am new for IGOR PRO programming and have a question about change column name for multi-dimensional wave.


Function test()

Make/N = (3,3) testwave

End


For testwave, it has 3 rows and 3 columns.
I am trying to change the name of testwave[][0] such as "number_of_atoms".
Unfortunately, when I try it by rename columns, all the waves from testwave[][0] to testwave[0][2] are affected.

Is there are commands for the designation of single column name?



Additionally, what is the role of $ in the command?
A multi-dimensional wave has one name. You can't have a separate name for each column.

You can have a separate column dimension label. Execute this for details:
DisplayHelpTopic "Dimension Labels"


You can also have separate column titles. Column titles are used only to label a column in a table. Execute this for details:
DisplayHelpTopic "Column Titles"


Setting the column title of a column of a multi-dimensional wave is tricky. You have to specify the column by its position in the table. See the example here:
DisplayHelpTopic "Modifying Column Properties"


[quote]Additionally, what is the role of $ in the command?[$quote]
$ converts a string containing a name into a name. For details, execute:
DisplayHelpTopic "Converting a String into a Reference Using $"
