MATLAB: Plotting in App designer

Question

Hello everyone,

I just started using AppDesigner, and I don't know how to plot a function inside a "UIAxes" graph. I created this figure using the items in the component library, but once I switch in the "Code view" mode, I don't know how and where to add strings code to plot the function. To start I would plot a simple function as "sin(x)" in the selected "UIAxes".

classdef App1 < matlab.apps.AppBase
    % Properties that correspond to app components
    properties (Access = public)
        UIFigure        matlab.ui.Figure            % UI Figure
        UIAxes          matlab.ui.control.UIAxes    % Telemetria

        UIAxes2         matlab.ui.control.UIAxes    % Telemetria
        LabelEditField  matlab.ui.control.Label     % Throttle
        EditField       matlab.ui.control.EditField % ------
        LabelEditField2 matlab.ui.control.Label     % F.Brake
        EditField2      matlab.ui.control.EditField % -----
        Slider          matlab.ui.control.Slider    % [0 100]
        UIAxes3         matlab.ui.control.UIAxes    % Track Map
    end
    methods (Access = private)
        % Code that executes after component creation
        function startupFcn(app)
        
        end
    end
    % App initialization and construction

Answer 1

x = 1:10;
y = sin(x);
plot(app.UIAxes,x,y);
