How do you graph Data filtered through a loop? This is for an app, I have a large table and a graph, but I also need to graph my filtered data.

% Code that executes after component creation
        function startupFcn(app)
            t = readtable('Corona 2.xlsx');
            app.UITable.Data = t;
            
            t = readtable('Corona 2.xlsx');
            app.UITable.Data = t;
            
            Day = table2array(t(:,"Day"));
            Deaths = table2array(t(:,"Deaths"));
            plot(app.UIAxes,Day,Deaths);
        end
        % Button pushed function: FilterStateButton
        function FilterStateButtonPushed(app, event)
            t = readtable('Corona 2.xlsx');
            app.UITable.Data = t;
            
            FilterState = app.StateFlipEditField.Value;
            
            numRows = size(t,1);
            
            k = 1;
            
            for i = 1:numRows
                if app.UITable.Data{i,4} ~= FilterState 
                    RowstoDel(1,k) = i;
                    k = k + 1;
                end
            end
            
           app.UITable.Data(RowstoDel,:) = [];
          
        end

You are already plotting something. Isn't good?

But I would like the plot to show UIAxes 2 as just the filtered state from the loop I created.

Hi,

I assume that you want to plot the filtered data on another axis after the button is clicked. For this, either you could use another axes on the figure or you could use sub-plot.

function FilterStateButtonPushed(app, event)
            t = readtable('Corona 2.xlsx');
            app.UITable.Data = t;
            
            FilterState = app.StateFlipEditField.Value;
            
            numRows = size(t,1);
            
            k = 1;
            
            for i = 1:numRows
                if app.UITable.Data{i,4} ~= FilterState 
                    RowstoDel(1,k) = i;
                    k = k + 1;
                end
            end
            
           app.UITable.Data(RowstoDel,:) = [];
           plot(app.UIAxes2,Day,Deaths); % You could add something like this 
                                         % at the end of call back to plot the filtered data
        end

You can also set visibility of an axes accordingly which is an in-build attribute for UIaxes.

Hope this helps!
