David,

Here is some code that will do a piece wise continuous plot:

sol=Table[FindRoot[Sin[x]-x/a=={0,x,2}],{a,2,3,.01}];
solab=Table[a,{a,2,3,.01}];
bb=x/.sol;
new=Table[{0,0},{k,1,101}];
For[i=1,i<102,i++,{new[[i,1]]=solab[[i]],
		new[[i,2]]=bb[[i]]}]
ListPlot[new,PlotJoined->True,PlotRange->All,
	Frame->True];

enjoy
