Axis tickformat overrides exponentformat settings

[suribabu39]

Hi,
I am getting 'G' as suffix for y axis ticks if I use tickFormat, if I don't use tickFormat then it would show it with suffix 'B'. As y axis ticks are numbers I would like to show them with 'B' (with Million, Billion, Trillion formatting).
Codepen link1
Is there a way to show that way? Should I change tickFormat?
I have also tried using exponentformat, but still I am not getting ticks in Billions format.

Thanks in advance,

maybe related to #1264

I just got bit by this too.

It's related to https://github.com/plotly/plotly.js/blob/master/src/plots/cartesian/axes.js#L1375

@etpinard what's the desired behavior? If so we should fixup or document.

D3 does not provide a numeric type (a) like numeral.js does.
https://github.com/d3/d3-format/blob/master/README.md#locale_format
so while semi related to #1264 I'm not sure you can fix it with just the locale.

Removing my tickformat all together, and then adding tickprefix: '$' worked in my case, but not ideal since I'd have to manually manage tickprefix so it's aligned with the locale

as an aside, I'm not seeing where the format functions use locales. Am I missing something?

That's correct, we don't use d3 locales anywhere in our code yet. You're correct, #1264 is a different problem, where layout.separators settings are overrode by tickformat.

@alexander-alvarez Thanks for digging around axes.js. Sounds like we'll need to partially reformat the output of d3.format instead of simply returning it.

Hi - this issue has been sitting for a while, so as part of our effort to tidy up our public repositories I'm going to close it. If it's still a concern, we'd be grateful if you could open a new issue (with a short reproducible example if appropriate) so that we can add it to our stack. Cheers - @gvwilson
