Multicategory axis type #3300

etpinard · 2018-11-30T17:36:25Z

(attempts to) resolves #2799 by adding a ✨ new ✨ axis type: 'multicategory' - which displays two (maybe more later) axis labels levels along with "dividers" in-between each category group.

N.B. This branch is up-to-date with the latest master that includes uirevision.

Things to TODO:

add support for type: 'multicategory' on y-axes
add support to heatmap and contours
add support in histogram* traces
~~[ ] add some way to configure ticks/dividers per category level~~ - leave for later
improve axis.automargin test coverage, partly done in: 80f4701, more to come in Allow replot during drag interactions #3305
test as many edge cases I can think of

Things skipped:

ticktext / tickvals are not coerced on type: 'multicategory' axes
support for transforms

cc @plotly/plotly_js @nicolaskruchten

- ax._mainLinePosition appears to be always defined for cartesian axes

- so that it can still be relevant for multi-category axes.

- no need to export it on Axes - return Lib.syncOrAsync result

- this will allow us to use ax._boundingBox for multicategory axes

... similar to ax._lw for ax.linewidth.

- compute and use tick-label height to position secondary labels - disallow 30deg tick label rotation when fixing overlaps - use ax._boundingBox to position axis title on multicategory axes.

test/image/mocks/multicategory.json

src/plots/cartesian/axis_autotype.js

- make it return z.length if z is 1D - make it return 0 when not an array

- mea culpa: no need to keep track of max-row-length for multicategory coordinate array, min-row-length suffices.

- make sure calc'ed arrays are sorted properly - handle null and undefined item correctly - handle non-2d-array input correctly - test 2d-array input on non-multicategory axes

- improve secondary-label to axis title padding - add horizontal violin mock

- lock down annotations in same mock.

this means Axes.getSubplots and Axes.findSubplotsWithAxis are essentially unused internally, but we have some outside callers using getSubplots

Clean up automargin pipeline a bit

💃 love it.

Just to make 100% sure:
Is it somehow possible to combine this with xaxis.type = "date" or linear if you want your datapoint to be between two ticks (divider style) and still keep the advantages of these axis types? (scalability and so on)
As it stands now it seems that showdividers is not compatible with xaxis.type = "date" to me.

As it stands now it seems that showdividers is not compatible with xaxis.type = "date" to me.

That's correct. Dividers are only available for type: 'multicategory' axes.

Hello, do you know when 'multicategory' type will displays more than two axis ? Is there a work in progress about it ?

elmadj · 2020-01-18T02:14:59Z

Hi is there support for something similar to bargap and bargroupgap with multicategory axes? The goal would be to have a different gaps between bars of an outer category and bars of an inner category. Thanks ! Any other way to achieve this would be helpful :)
