Question: How to create a bar graph?

Hi, I would like to represent the piecewise function as a Bar Graph. I can only get a line Graph. Thanks in advance.
 

EXAMPLE 8 Interior Design Services Employees

 

"N(t):={[[-4.64 t +76.2 ,7<=t<=10],[0.90 t+20.0,11<=t<=12]]"

proc (t) options operator, arrow, function_assign; piecewise(7 <= t and t <= 10, -4.64*t+76.2, 11 <= t and t <= 12, .90*t+20.0) end proc

(1)

"->"

 

 

For 2007:

N(7) = 43.72 thousand employees

For 2011:

N(11) = 29.90 thousand employees``
