[GitHub] [incubator-superset] li-ana opened a new issue #12005: Boxplot - wrong logic
li-ana opened a new issue #12005:
URL: https://github.com/apache/incubator-superset/issues/12005
Box plot assumes that you will have only 1 observation per timestamp. In my case, this is not true, which means that the box plot will aggregate all of the observations per timestamp using the function that you select, thus it skews the results. It needs to look at raw data, instead of the aggregation.

While we don't yet support using the full raw data, and then calculating the boxplot on that, we recently migrated Boxplot to ECharts and added some features in this PR: #11199 . In the below example I've created a Boxplot where the categories are continents and the distribution is calculated across countries (I'm using the average of total population, as the dataset contains data for multiple years):
If you have a row id, you can use that as the the "Distribute Across" parameter. The plan is to add support for using the raw row data, but I probably won't have time to work on it any time soon.
