Y-axis number formatting: No attribute to denote negative Y-axis numbers inside brackets for chart type mscolumn2d

[s-ghansiala]

The default behavior is to denote negative numbers by prefixing '-' sign before them and positive numbers without any prefix, can we alter this way of denoting numbers?

Here is a snap of my local policy settings:

Example my requirement is to denote negative numbers inside brackets (dictated by locale policy of some users), so on Y axis -25 should be shown as (25), positive numbers shall be shown normally. I can't find any attribute to set the negative number format according to my locale policy. Is this achievable?
