This PR aims at allowing users to display the total of each bar on top of it (bottom of it for negative values).

TODO:

• [X] Need description: see #85
• [X] Base implementation
• [X] Lint
• [ ] Add tests
• [ ] Add documentation

[wilhelmhb]

I haven't yet been able to run the tests, probably a browser/configuration issue. Thus I haven't started on the jasmine tests. I can provide a few test cases if needed. I don't really see where the documentation is written, but if someone points me in the right direction, I'll be glad to add a few examples.

Any update on this ?

Thanks for this PR! Our team is currently working hard on finishing up the 2.0 release of Plotly.js which explains our radio-silence for the past while, and I apologize for not communicating more clearly about it. This PR should probably land in 2.1, which we expect to come out in April. I'm sorry for the long timelines here :)

@nicolaskruchten Hello! I am interested in using this feature. Now that we're reaching April 2022 and plotly 2.11, are there any updates on this PR?

@vovavili could you please fetch upstream/master and merge it into this branch?

@nicolaskruchten @archmoj I've just merged upstream/master in this branch I removed a typo, and added an example in test/image/mocks/bar_stackrelative_negative_total.json, available when you run npm start, then lookup the filename in the mocks search field.

I personally have a weird result on my machine. However, as I have the same result when using any text with textposition : outside, I'm assuming this is an issue with plotly.js, which should be a separate matter.

I'm still unable to run the jasmine tests on my machine.

Hoping this can still make it to 2.13

Hi there is any update?

[archmoj]

Thanks @wilhelmhb for the great PR. My apologies for the late review. Kindly find my comments regarding the new attributes. Before adding new tests, I also suggest that you possibly pull upstream/master and merge it to your branch. @alexcjohnson it would be great if you also provide a review. Thank you!

October 2023, I could really use this feature. Thank you.

@archmoj @alexcjohnson How is the review going? It would be really helpful to display totals for bar charts.
