Meta Index / Home Page / Description / Detailed layout of GUI / Column selection
Integer columns are suitable to serve as primary axis in image and
spectrum/histogram extractions and, thus, have two associated check buttons
left to it.
To the right are two numerical, editable entry fields which determine
the minimum and maximum allowed value of the quantity in that
column. If the focus is set in a field, the user can simply type in new
values or use the up and down arrows next to the field to increase or
decrease the displayed value by 1.
Pushing the button with the column name will then determine whether
any of the fields has been changed, construct a valid selection expression
of either form
and append this to the global expression in the top
expression entry field.
If the column possesses associated hard upper and/or lower limits
these will be indicated in the attached text label and non compliant
user inputs will not be accepted.
