Your graph should start at the origin of the two axes. If you have zero load, you have zero deflection of the proving ring. Add load in consistent increments. For example, if you expect a total load of "X" then do increments of 0.1X. This should give you a reasonable plot of load vs. deflection of the proving ring.
