Hello everyone,

![image](https://discourse.paraview.org/uploads/default/original/2X/e/e05c89f4faa549b1caceb0a76db510aa4e794aba.png)

![image](https://discourse.paraview.org/uploads/default/original/2X/0/0eccf837b135a85110a087b205013f240f01fefc.png)

I have a problem with the calculator, although I put the “” in my text. Is it a problem with the values?  
The field 7 has the interval [3;11], can I change the intervals in the calculator?  
Thank you for your help.  
Pauline

`iHat*"Field 7" + jHat*"Field 4" + kHat*"Field 7"` calculator expression works great.
