Plotting the output of an FIS appropriately.

Am implementing an FIS (Fuzzy Inference System). I want to plott the output in a UIAxes, I used this code:

function Diagnose(app)

handles.fisfile='Psychiatric Diagnosis FIS Model.fis';

%guidata(hObject,handles)

fisfile=handles.fisfile;

fis=readfis([fisfile]);% load the Fis file

%%%% read 5 inputs

input=([app.in1,app.in2,app.in3,app.in4,app.in5]);

[output,fuzzifiedIn,ruleOut,aggregatedOut,ruleFiring] =evalfis(fis,input);

%Plot 1st output{1}

app.op1 = output(1);

outputRange = linspace(fis.Output(1).range(1), fis.Output(1).range(2), length(aggregatedOut));

plot(app.UIAxes1,outputRange,aggregatedOut,[app.op1 app.op1],[0 1]);

app.DO1.Text = num2str(app.op1);

%Plot 2nd output

app.op2 = output(2);

outputRange = linspace(fis.Output(2).range(1), fis.Output(2).range(2), length(aggregatedOut));

plot(app.UIAxes2,outputRange,aggregatedOut,[app.op2 app.op2],[0 1]);

app.SIO2.Text = num2str(app.op2);

%Plot 3rd output

app.op3 = output(3);

outputRange = linspace(fis.Output(3).range(1), fis.Output(3).range(2), length(aggregatedOut));

plot(app.UIAxes3,outputRange,aggregatedOut,[app.op3 app.op3],[0 1]);

app.RTBO3.Text = num2str(app.op3);

return

end

I get the deffuzzified output but it is mixed up with unwanted and meaningless graph. As in the picture bellow, How can I get a clean Output as deffuzzification without the wrong (marked wrong) additions? Or, How can I plott FIS output appropriately? Thank you!
