Ability to exclude specific data from the widget display

[nino-filigran]

Use case

If a user needs for instance, to see the evolution of entities created, having a label starting with a specific chain of characters, if the amount of different labels is different than 5, this use case cannot be achieved for different reasons:

• lines, bars, area are limited to up to 5 data sets
• if user selects all labels starting with these characters in a single dataset, they'll be in column, without any breakdown per label (if breakdown per label would be possible, potentially some unwanted labels would be displayed, given that a label is often not alone)
• using a distribution list does not showcase an evolution but could be already a first step, however the labels displayed are not necessary the ones in the query, but the ones being used in conjonction with the ones in the query (we cannot restrict what we want to display to only the one in the query)

Current Workaround

• number visualisation per label: work fine, however it does not represent an evolution, only a number.
• create X amount of lines/area/vertical bars (X being equal to amount of label/5): 5 being the amount of data sets allowed for these widgets

Proposed Solution

Several solutions are possible:

1. Increase the amount of datasets per lines/area/vertical bars (drawback: might cause issues if all the query are complex but potentially the easiest solution)
2. Introduce the operator "starts with" on labels & allow users on widgets visualisation to "breakdown per values found" (most elegant solution, however technically might be challenging)
3. Introduce the ability, if multiple values are selected in the filters section, to breakdown for each of the values contained in the query (middle ground solution, that would still potentially complex to achieve)
