![]() The data type of each table array variable controls formatting for the corresponding column in the app. Changing the RowName property of the Table UI component updates the UI, but it does not update the row names in the table array. Changing the ColumnName property of the Table UI component updates the UI, but it does not update the variable names in the table array.īy default, the row names displayed in the app match the RowName property of the table array. When you specify the Data property of a Table UI component as a table array, then MATLAB sets the format of the Table UI component automatically based on the values in the table array:īy default, the column names displayed in the app match the VariableNames property of the table array. By contrast, the uitable function creates a Table UI component (a user interface component for an app). The table, readtable, and array2table functions create table arrays. ![]() Table arrays provide a convenient way to store tabular data as a MATLAB variable. ![]() In App Designer and apps created using the uifigure function, you can specify the Data property as a table array. When a user edits a cell, the Data property updates. To prevent warnings or NaN values that display when users enter invalid data into an editable cell, write a CellEditCallback function to convert the data to the appropriate type. String array - Displays characters and text.Ĭell array of character vectors - Displays characters and text. true values correspond to selected boxes, whereas false values display cleared boxes.Ĭell array - Displays any combination of numeric, logical, or character array values. Numeric array - Displays numeric values such as double or single. % SIMPLEAPP Interactively explore plotting functions % Choose the function used to plot the sample data to see the % differences between surface plots, mesh plots, and waterfall plots % Create figure windowĭd.Table array ( uifigure-based apps only) - Displays any combination of data types that table arrays support, such as datetime, duration, and categorical. Call the appropriate plotting function and specify the input axes as the axes to plot on. In the callback function, access the new drop-down value using the event argument and then use this value to determine how to update the plot data. Define changePlotType to accept src and event in addition to a third input argument that specifies the axes to plot on. The first argument contains the component that triggered the callback, and the second argument contains information about the user interaction. These input arguments are often named src and event. MATLAB automatically passes two input arguments to every callback function when the callback is triggered. In the simpleApp.m file, after the simpleApp function, define a callback function named changePlotType. In this example, program your app to update the plot when a user selects a new drop-down item. Write a callback function and assign it to an appropriate callback property to control the behavior of your app. ![]() Every UI component has multiple callback properties, each of which corresponds to a different user interaction. A callback function is a function that executes when the app user performs a specific interaction, such as selecting a drop-down item. Program your app to respond to user interactions by using callback functions.
