Especially since #27721 is a probably better solution to the same meta problem. \r\n\r\n### Problem\r\n\r\nLots of requests for colormapping unitized data, such as #7383,  #25062, #23991,  #19476, #17447\r\n\r\n### Proposed solution\r\n\r\nSince the number -\u003e number that can be colormapped conversion is done in the norm, proposing that we make an explicit Norm for handling units:\r\n\r\n### `UnitizedNorm`:\r\n\r\nCreate a new norm object `UnitizedNorm`:\r\n\r\n  * maps data to numbers using `{Convertor}.convert` \r\n  * labels colorbar using the formatters from `{Convertor}.axisinfo`\r\n\r\nThe hard work here is integrating this into the existing color-mapping pipeline, particularly the interpolation pipeline. One approach may be to add a flag indicating whether the unit can participate in existing schemes or whether it provides its own interpolation methods. If this works, then `.UnitizedNorm` can be shimmed in to act as an analogue to `NoNorm`\r\n\r\n### `UnitizedNorm(Normalize)`\r\n\r\nI don't know if this is actually possible, or remotely worth the effort given @ksunden's work, but a follow on proposal is that  `UnitizedNorm` acts as a wrapper around `Normalize` objects so that the norms can take in unitized inputs, where `UnitizedNorm(NoNorm) == UnitizedNorm()` is the default described above. The objective would be to allow support for things like \r\n`UnitizedNorm(BoundaryNorm(['2011-01-01', '2011-02-01', '2011-03-01']))' or \"UnitizedNorm(Normalize(vmin=Pint(10))\" \r\n\r\nPretty sure that if this is possible, it ends up being some sorta dynamic monkeypatching of the existing class. But also if possible then it can be written as a decorator and that would be nice to have for custom Norms. \r\n\r\n\r\n","author":{"url":"https://github.com/story645","@type":"Person","name":"story645"},"datePublished":"2024-01-26T18:01:56.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/27706/matplotlib/issues/27706"}
