// Solution 

// Given
O= 150*10^3;// energy consumption in office heating in Watts
L= 120*10^3;// energy consumption in lighting in Watts
B= 90*10^3;// energy consumption in boiler house in Watts
P= 180*10^3;// energy consumption in process in Watts
// Pie Chart Representation : one input argument  x=[O L B P]
pie([O L B P],["office heating" "lighting" "boiler heating" "process"]);// Please see the graphics window
