A GUI to Set Simulink

Model Parameters (GUIDE)

• Create an axes, set its Paren t property to the figure handle, and save the

axes handle.

• Create the plot (which is one or more line objects), save these line handles,

and set their

Parent properties to the handle of the axes.

• M ake the figur e v isible.

Plot Button Callback Listing

Here is the Plot button callback.

function PlotButton_Callb ack(hObject, eventdata, handles)

currentVal = get(handles.ResultsList,'Value');

% Get data to plot and generate command string with color

% specified

legendStr = cell(length(currentVal),1);

plotColor = {'b','g','r','c','m','y','k'};

for ctVal = 1:length(currentVal);

PlotData{(ctVal*3)-2} =

handles.ResultsData(currentVal(ctVal)).timeVector;

PlotData{(ctVal*3)-1} =

handles.ResultsData(currentVal(ctVal)).outputVector;

numColor = ctVal - 7*( fl oor((ctVal-1)/7) );

PlotData{ctVal*3} = plotColor{numColor};

legendStr{ctVal} = ...

[handles.ResultsData(currentVal(ctVal)).RunName,'; Kf=',...

num2str(handles.ResultsData(currentVal(ctVal)).KfValue),...

'; Ki=', ...

num2str(handles.ResultsData(currentVal(ctVal)).KiValue)];

end

% If necessary, create the plot figure and store in handles

% structure

if ~isfield(handle s,'PlotFigure') ||...

~ishandle(handles.PlotFigure),

handles.PlotFigure = ...

figure('Name','F14 Simulat ion Output',...

'Visible','off','NumberTitle','off',...

'HandleVisibility','off','IntegerHandle','off');

handles.PlotAxes = axes('Parent',handles.PlotFigure);

guidata(hObject, handles)
