Hi,

would it be possible to construct scalar field directly from the data column instead of using "global variable". Recently, I made several scalar field and some of them where the results of mathematcal opperation between other scalar fields. To do so, I needed to
1- Create an expression column
2- Change the expression column to number column
3- Copy the column I will used for "X","Y" and "value" into a "Global variable>Scalar field"

Also, if I needed to change some of the data column it require me to delete the "Global variable>Scalar field" and create a new one to be able to update the column valu because, once the scalar field was created, I was unable to copy additional collum or row into it.

At the end, I didn't find it really "user friendly" and I think it would be more easier for the user (but may be not for the developper) to manage scalar field as all other plot. By choosing which column is used for "x", "y" and "value" directly from the data column rather than by creating a "global variable>scalar filed".
