MATLAB: Loading a generated array into a visible table in AppDesigner

app designerdata importimportStatistics and Machine Learning Toolboxuitable

Hi everyone,

I am creating an application that can be used to display imported data into a table, plot the same data into histograms, scatter plots and general plots.

I have two issues that I would like help on.

How do I pass the results obtained from one function to the next function. for example, how do I get my imported data to plot without repeating the whole code?

Secondly, how can I display my already imported data in form of a table in AppDesigner as it is

"How do I pass the results obtained from one function to the next function. for example, how do I get my imported data to plot without repeating the whole code? "

There are several ways to do this. Assuming the import function is defined within your appdesigner file, the cleanest method would be to merely pass the data into the plotting function as an additional input. Alternatively, you could store the data in the "UserData" property of the axis handle and then retreive it from within your plotting function.

app.UIAxes.UserData = myData;   %store the data
myData = app.UIAxes.UserData;   %retrieve the data from within the plotting function

Secondly, how can I display my already imported data in form of a table in AppDesigner as it is

Here's instructions how to set up the table when the app first starts

And here are some demos showing how to update the table once there is new data

The question is mostly clear and the image is helpful. Interesting approach to align the buttons with the UITable rows - I like it. Your use of a general callback function assigned to all buttons is also well organized.

Since there are many variables in your code and we can only guess what they are, here's the general approach and you can let us know how it differs from what you're doing.

The startup function should initialize the table with what appears to be 8x2 matrix of 0s (7 buttons + total). That would look like app.UITable.Data = zeros(8,2);
Assuming the index input to the ButtonPushed function is the row number, you just need to gather the row of values into a 1x2 vector and assign it to the correct row.

newData = [app.dataStructCounts, app.dataStructPercentage];
app.UITable.Data(index,:) = newData;

You can use the handle of the uitable to get the data inside it in the form of a table object

data = app.UITable.Data;

app.UITable is the handle of the uitable in app designer. Change it according to the name of you uitable.
