Scatterplot: select the columns based on colnames rather than position in the table

[KristinaGomoryova]

Hi! Would it be possible to change in scatterplot the numerical columns choice based on the colnames rather than the position in the table? Especially in the larger tables it gets impractical to find the correct columns position :)

Thanks for the consideration!
