Function Arguments Using Nargin

I want to control the arguments (data sets) in a function to plot. So if I push in only one data set (x1,y1) into the function, it will plot that data and not get an error that x2 is empty or cleared variable. Or if I push in two data sets (x1,y1,x2,y2) it will plot that. Here is the code:
%.........................
%testing data set
%.........................
x1 = [1 1 1 1 1];
y1 = [1 2 3 4 5];
x2 = [2 2 2 2 2];
y2 = [1 2 3 4 5];
%...........................
function plotinputs(x1,y2,x2,y2)
if nargin == 2
plot(x1,y1)
else nargin == 4
plot(x1,y1,x2,y2)
end
Thanks, Amanda

I knew I was missing some pieces in the code. I will check out the reference. Thanks a lot.

There is an error
function plotinputs(x1,y2,x2,y2)
it should be
function plotinputs(x1,y1,x2,y2)
