index-y interaction mode + convert horizontal bar defaults to new mode #4458
Conversation

Some thoughts: instead of duplicating modes for both axes, maybe we should introduce a new interaction options to select the orientation (
Could also apply to nearest and index:
(though not sure |
|
@simonbrunel that would work. Axis x would do the current behaviour, axis 'y' would do the new behaviour. I don't know that 'xy' is needed but we could add it for completeness |
|
Looks good (unit tests are failing though). Do we want unit tests for this new options? |
|
I thought I fixed those tests. will check again |

Since these tests use the same chart input, we could refactor it in beforeEach() under the describe ('intersect: false'...` block?

Might be easier and more accurate to generate a Chart.js event instead (nativeEvent: null)?
|
Tests look fine, I would maybe also add tests for cases where it's supposed to return no elements (I don't know it that makes sense). |

Updated per the comments. I cleaned up all the tests to use |

I think it's a bit cleaner to use this.chart instead of a global variable.

Awesome! Updated per your comment 😄 |

This new mode resolves #3905 and works much better for a horizontal bar chart when
intersect: false
