Easiest way to control the labeling of the x axis is to define an x axis array. 
You can also remap the x tick labels in the axis properties but 1) that is 
harder, 2) basic plot mechanisms should be learned first.

Assuming linearity mapping your 722 points to 0 to -180 then you would need 
code similar to the following:

# start code
myarray = rand( 1, 100 );       % test purposes only
points = length( myarray );
range = [ -180 180 ];
xticksSize = diff(range) + 1;
stepSize = xticksSize / points;
xticks = range(1):stepSize:range(2);
semilogy( xticks, myarray, "color", "g" );
# end code
