[Paraview] "Plot Data" filter has problem with negative values

[FERHAT HAMIDA Abdelhak]

Thank you Utkarsh AyachitAfter your reply, I found the origin of my problem.In a previous run, I used a semilog plot by enabling "Left Axis Log Scale" and saved the setting as default one. Paraview saves the setting in the file : $HOME/.config/ParaView/ParaView-UserSettings.json
 In the following runs, "Left Axis Log Scale" is enabled by default and ParaView do not accept negative values for "Left Axis Range Minimum" even if I disable  "Left Axis Log Scale".
To solve the problem, I disable "Left Axis Log Scale", save the settings and restart ParaView. (If I do not restart, I still in the same situation until next run). The changes do not take effect in the current session.
So, I this is not a normal behaviour, it can be a bug.
Best regards.

 I am not able to reproduce the problem. Attached is a state file and
