App Designer | Can't get back from 3D plot to 2D plot when changing list item

Hello,

Please assist me with my issue below. The code may seem lengthly but is simple.

I have an app where I change a list selection between 2D and 3D plots, however when changing back to 2D it shows my points on a 3D plot (please image attached).

Here's my plotting function:

function plotGraph(app, plotType, plotXt, plotYt, plotZt, plotTt, plotHt)
           if nargin < 6
               if nargin == 4
                    switch plotType
                        case 'Scatter'
                            scatter(app.UIAxes, plotXt, plotYt)
                        case 'Line'
                            plot(app.UIAxes, plotXt, plotYt)
                        case 'Histogram'
                            histogram(app.UIAxes, plotXt, plotYt)
                    end
               else  
                   switch plotType
                        case 'Scatter'
                            scatter3(app.UIAxes, plotXt, plotYt, plotZt)
                        case 'Line'
                            plot(app.UIAxes, plotXt, plotYt, plotZt)
                        case 'Histogram'
                            histogram(app.UIAxes, plotXt, plotYt, plotZt)
                   end
               end   
           end
end
           

which I call via the listValueChanged function:

app.ListBoxPlotNames.ItemsData = 1:numel(app.ListBoxPlotNames.Items);
valueIndex = app.ListBoxPlotNames.ItemsData;
value = app.ListBoxPlotNames.Value

currentTable = initTable.data{value}
noColsDisp = width(currentTable)

plotX = table2array(currentTable(:,1)) 
plotY = table2array(currentTable(:,2)) 

switch noColsDisp
    case 2
        plotGraph(app, plotType, plotX, plotY);
    case 3
        %app.UITableImport.Data(:,3) = currentTable(:,3);
        plotZ = table2array(currentTable(:,3))
        plotGraph(app, plotType, plotX, plotY, plotZ);
end

When clicking on the ListBox function to go back to 2D I get this print out in command window:

currentTable =

  10×2 table

     Var1     Var2
    ______    ____

     192.3     -9 
    192.31     -1 
    192.32     24 
    192.32     35 
    192.33      6 
    192.34     -4 
    192.34      6 
    192.35     20 
    192.36      4 
    192.37      6 

    % Note below noColsDisp = 2, therefore case 2 = plotGraph(app, plotType, plotX, plotY) should run (and to my knowledge does, but remains 3D?
noColsDisp =

     2


plotX =

  192.3024
  192.3094
  192.3164
  192.3233
  192.3303
  192.3373
  192.3442
  192.3512
  192.3582
  192.3651


plotY =

    -9
    -1
    24
    35
     6
    -4
     6
    20
     4
     6
     
     

No plotZ is created?

Thank you for going through it and for your time.

Kind regards,

Shouldn't you be using plot3() and histogram2()?

Hi,

Can you try the following modified 'plotGraph' function & confirm if it works?

function plotGraph(app, plotType, plotXt, plotYt, plotZt, plotTt, plotHt)
           app.UIAxes = [];
           app.UIAxes = axes;
           if nargin < 6
               if nargin == 4
                    switch plotType
                        case 'Scatter'
                            scatter(app.UIAxes, plotXt, plotYt)
                        case 'Line'
                            plot(app.UIAxes, plotXt, plotYt)
                        case 'Histogram'
                            histogram(app.UIAxes, plotXt, plotYt)
                    end
               else  
                   switch plotType
                        case 'Scatter'
                            scatter3(app.UIAxes, plotXt, plotYt, plotZt)
                        case 'Line'
                            plot(app.UIAxes, plotXt, plotYt, plotZt)
                        case 'Histogram'
                            histogram(app.UIAxes, plotXt, plotYt, plotZt)
                   end
               end   
           end
end
