Dear Karthik, sorry, I was a bit unprecise! There is no context menu for the property node, but if you click right on the graph belongig to it on the front panel than you will get a context menu. There you have to disable "auto scale" for the y axis. This should be menu item under y axis or similar (unfortunate I have a german version of LabVIEW, so I'm not aware how the correct names of the menu items og the english version might be).
