[Feature Request]: Manually set levels for data that is missing e.g. for distribution plots

[maximusmontis]

Description

Currently, the amount of categories in a distribution plot (i.e., the x axis) is determined automatically by JASP. I am currently working with a dataset, where participants responded to a series of questions with a rating of 1-4 (i.e., four response categories). In some questions, no participants selected the response "1". JASP now understandably assumes that this response option does not exist and therefore displays only the categories 2-4 in the distribution plot.
This complicates the comparison of the plots (see example below), because the information that zero participants selected response option 1 gets lost.

Purpose

No response

Use-case

No response

Is your feature request related to a problem?

Descriptives

Describe the solution you would like

It should be possible to manually set and label the amount of categories on the x axis.

Describe alternatives that you have considered

No response

Additional context

Plot with four categories (correct)

Plot with three categories (incorrect, response option 1 is missing, since no participants selected this option. Nevertheless, this is relevant information and should be possible to display in the plot.)

thx for the report.
This is also true for flexplot.
At the moment our graph-editor only allows x-axis editing of metric/scale variables. As a temporary workaround you could switch the variabel to scale, then click on "edit image" and alter the x-axis settings.
But this should certainly not be neccesary. Let's hope that this can be implemented for 0.20 or later.

I would recommend you convert A203_06 into an ordered factor. That will preserve both the order and the slot for the zeroes even if you don't have any answers for that. I don't know that I can modify flexplot to make that always the case because it would have no way of knowing that zero is supposed to be the minimum.

Just to let you know - there is a fix for this now included in the latest nightlies. If you want to test:
https://static.jasp-stats.org/Nightlies/

But those might be unstable.

See this pull request for how this is supposed to work now via manually adding levels of data that is not really there:

Please reopen if you disagree that this solves this problem.
