representing data in pie chart

hello everybody i wanna represent data in pie chart:

and i got stuck when the sum of values is less than 100:

a2=input("please enter numeric values using '[ ]' : ");

if sum (a2)>=100

pie(a2)

else

labels = {'data','Other'};

pie(sum(a2),100-sum(a2),labels)

pie(X) draws a pie chart using the data in X

• If sum(X) ≤ 1, then the values in X directly specify the areas of the pie slices. pie draws only a partial pie if sum(X) < 1.
• If sum(X) > 1, then pie normalizes the values by X/sum(X) to determine the area of each slice of the pie.

But if you dont want a partial pie when sum(X) < 100 you can use if condition and calculate the other variable value and plot it.

As an example

a2=input("please enter numeric values using '[ ]' : ");
if sum(a2)>100
    disp('Invalid Entry: Sum Greater than 100');
elseif sum(a2) == 100
    pie(a2);
else
    others = 100 - sum(a2);
    a2 = [a2, others];
    pie(a2);
end

Hope this helps!
