No option for tickformat with '(' (parentheses) sign

[OmriAroesti]

As specified here, the formatting is described as the same as d3's formatting language.

However, the d3 documentation this points to mentions that "the sign can be... ( - nothing for zero or positive and parentheses for negative.".

This option, however, is not available to plotly.js.
I see that the d3_format_re is in fact /(?:([^{])?([<>=^]))?([+\- ])?([$#])?(0)?(\d+)?(,)?(\.-?\d+)?([a-z%])?/i, and does not include the ")" along with "+", "-" and " "(space), so it defaults back to -.

This is likely because Plotly.js uses an older (v3) version of d3_format. We will be able to upgrade to the latest formatter soon :)

Right - until we manage to upgrade d3-format, the docs should really be pointing to the d3v3 version of the package, as we do in some of the attribute docstrings:

plotly.js/src/constants/docs.js

Line 4 in cfa7720

FORMAT_LINK: 'https://github.com/d3/d3-3.x-api-reference/blob/master/Formatting.md#d3_format',

@archmoj we can close this one right?
