This graphic is incorrect. This is a similar graphic to the Charles's law illustration (which is correctly done): File:Charles and Gay-Lussac's Law animated.gif. The fixed mass load piston on the left illustrates a FIXED pressure. Which contradicts the VARIABLE pressure gauge shown at the same time. These are mutually exclusive. At a minimum, the fixed pressure piston must be removed to correct this graphic. Also not shown, is the heat flows in and out of the gas piston required to keep it "contant temperature".
