May be trying to over analyze this but just curious....
So I had a question ... the climb weight limit line on a performance chart determine a weight which ensures a climb gradient of not less than.....
So would it be a different answer if you’re talking about the climb weight limit line on a landing chart to a take off chart? Because if you’re in the landing configuration you have to have a climb gradient of 3.2% but in take off... it has to be 6% in the take off configuration....

Exactly the case.
WAT - (maximum) Weight for Altitude and Temperature - limits are "line-in-the-sand" climb requirements to match up with the various minimum climb gradient certification stuff. They make sure that the aeroplane has a modest minimum climb performance.
For lighties, it is fairly simple while, for heavy iron, it gets more complex. For heavy takeoff, we have to check for four separate climb limits (for the various takeoff segments) rather than the one for lighties and two for landing rather than the one for lighties.
