Hi,

I have trouble understanding the GUI plot. I was able to get a figure pop out (as shown in Figure) on button click, but I am not able to build a GUI chart within the app, which would connect to run a whole scenario or be activated by an additional click on the button (as shown in attached GUI plot). I was not able to figure out how to assign my result for axses in the GUI. I copied the function code from GUI code view and the Figure pop out. Could you please advise how create figure that will show up in the GUI plot (as shown in the example GUI plot)?

Thank you for your help.

Kind regards,

Jasmina

function plotSpearman(app, runNum, topN) %Generate plot of top N Spearman rankings for given run number
            numResults = length(app.Building.RunHistory);
            names = cellstr(app.Building.RunHistory(runNum).SpearmanTable{1:topN,'Name'}); %Names of parameter (not necessarily attribute name, esp for U-vals and other SpearmanExtras)
            names = regexprep(names,'_','\\_');%Prevent converting text wtih underscores to subscripts
            vals = app.Building.RunHistory(runNum).SpearmanTable{1:topN,'Norm_squared_rho'}; %Normalized squared Spearman rho
            % vals = app.Building.RunHistory(runNum).SpearmanTable{1:topN,'P_value'}; % P_value
            
            fig = figure;
            barh(vals);
            title('Attribute ranking');
            xtxt = sprintf('Normalized squared\n Spearman rho');
            xlabel(xtxt); 
            set(gca,'YTickLabel',names); %Labels for bars. 
            set(gca,'Position',[0.35, 0.15, 0.60, 0.75]); %Set position of axes within figure
            set(gca,'YDir','reverse'); %Plot most influential first
            set(gca,'YLim',[0,topN+1]); %Set limits of y-axis to avoid any annoying extra white gap
            out = fig;  
        end

Figure:
 % Callback function: SpearmanRunListBox, SpearmanresultsButton
        function SpearmanresultsButtonPushed(app, event)
                app.plotSpearman(1,30);
           
        end

在 MATLAB Online 中打开

You must specify the axis handle in all graphics functions when plotting to a UIAxes in AppDesigner.

Assuming the app's axis handle is app.UIAxes,

barh(app.UIAxes, vals)
title(app.UIAxes,'myTitle')
xlabel(app.UIAxes,'myXLabel')
ylabel(app.UIAxes,'myYlabel')
ylim(app.UIAxes, [0,topN+1])
set(app.UIAxes,'YDir','reverse') % Or app.UIAxes.YDir = 'reverse'

etc.

Also, remove the call to figure() since that is produing an external figure.

Many of the axis properties can be set from within the AppDesigner user interface but you can also set many of those properties from within any function that has access to the axes handle.
