How do I get the percentage of row to sum of column?

[UrDub]

I would like to create a new column that will show the percentage of each row of a column with the sum of that column. If the column name is "february", I would like to do the following:

new column expr=february/<sum-of-february>

what should I place in <sum-of-february>?

If I understand you correctly you want to add up all the float values in a column? If so, use z+ and "sum" when on the column you want to add up. This wil show the sum of the column in the status bar. Hope that helps!

[UrDub]

that is right, the sum of the column. however, instead of doing z+ and typing in the result in
new column expr=february/<columnsum>,
I would like to do it programatically, like
new column expr=february/february.sum.
Does visidata have a method or variable that corresponds to february.sum?

There is a somewhat similar solution here, though I agree there ought to be a simple column.sum method to define new columns with aggregated values on the fly (or perhaps there is, and we could not find it in the docs).
