    Hi,

     

    you can use Generate Attributes for this. Something like

     

    if(attribute=1.5,1,attribute)

     

    should do it.

    @bibo59 You might consider making your expression a bit more flexible.  Martin's solution works if the higher value is exactly 1.5, but not for other values.  So instead you could use an if statement like this: if(attribute>1,1,attribute).

    Or you could directly use the MIN function like this: min(1,attribute).
