reset pareto chart on App Designer

I am developing a GUI with App Designer. One of its components is a pareto chart which is created with the function

pareto(app.MassParetoChart,masas,names_comps,1)

where the app.MassParetoChart is an App Designer UIAxes. Whenever the user inputs data is modified and the user produces a new pareto chart with the new input data, first the following commands are employed to reset and clean the UIAxes:

cla(app.MassParetoChart); clf(app.MassParetoChart); reset(app.MassParetoChart);
% Replot with the new data:
pareto(app.MassParetoChart,masas,names_comps,1)

However, after a few runs, the plot somehow is not entirely reseted and older axes apparently remain as can be seen in this figure

Trying the variant:

cla(app.MassParetoChart,"reset"); clf(app.MassParetoChart,"reset"); reset(app.MassParetoChart,"reset");

also presents the same issue appart from opening a new figure window outside of the App Designer app window:

What would be the right approach to correctly address this issue?

Update:

The correct reset of the pareto( ) plot can be done as follows:

Generating the figure and storing the objects

[par_charts,par_axes] = pareto(app.MassParetoChart,masas,names_comps,1);
app.figParetoObjs.par_charts=par_charts;
app.figParetoObjs.par_axes=par_axes;
Then, whenever it is required to plot new results and

Then, whenever it is required to plot new results and

cla(app.MassParetoChart); 
reset(app.MassParetoChart);
delete(app.MassParetoChart.Children)
if ~(isempty(app.figParetoObjs.par_axes))
    delete(app.figParetoObjs.par_axes(2));
end

I am not sure if all the commands (cla(),reset(),delete()) are required but some or all of them are doing the trick.

pareto creates a new axes and returns the two axes as the second output. You can store that new axes and cla(_,'reset') it along with your original uiaxes.

To demonstrate, step through this code in your command line:

f = uifigure('AutoResizeChildren',false);
ax = uiaxes(f);
[p,new_ax] = pareto(ax,rand(10,1)); % new_ax contains the original uiaxes ax and the new axes
cla(ax,'reset')
cla(new_ax(2),'reset')

Then adapt for use in your app.

Hello. Thanks for replying.

I am trying the following to generate the figure:

[par_charts,par_axes] = pareto(app.MassParetoChart,masas,names_comps,1);
app.figParetoObjs.par_charts=par_charts;
app.figParetoObjs.par_axes=par_axes;

Then, whenever the inputs are changed and replotting is required, the figure is reset with these commands:

cla(app.MassParetoChart,"reset"); 
if ~(isempty(app.figParetoObjs.par_axes))
    cla(app.figParetoObjs.par_axes(2),"reset");
end

Unfortunately, the pareto( ) behaves erratically, not even showing the actual figure:

As an alternative:

Whenever the inputs are changed and replotting is required, the figure is reset with these commands:

cla(app.MassParetoChart); 
if ~(isempty(app.figParetoObjs.par_axes))
    cla(app.figParetoObjs.par_axes(2));
end

The situation is basically the same as the one described on the original post.
