How do I get information about selected column in UItable?

First of all,

I would like to make matlab app as below in appdesigner

1. Make table from data
2. Select column from table I want to see
3. Plot data which selected column from table.

So I tried to get event.Indices, but actually I don't know how to do that

Some colleagues replied that just use below kind of function, but matlab says no field named Indices like below fig.

Actually, I just would like to see how event.Indices are structed so that I use the structure to handle data.

Could you please help me out?

Thanks

@병주 김 - I think the problem is that you are trying to get the Indices from the event object of the push button callback and not the UITable cell selection callback. I think that you want to do something similar to https://www.mathworks.com/matlabcentral/answers/364338-how-to-get-indices-of-selected-uitable-cell-outside-cellselection-callback (which I see you have commented on) so that the cell selection callback does the following

% (Add selectedCell property to store indices)
% Cell selection callback: UITable
function UITableCellSelection(app, event)
    app.selectedCell = event.Indices;
end

and that your push button callback would then get that data and use it to plot

function CallbackButtonPushed(app, event)
    % get the data from the table using app.selectedCell
    % plot the data
end

So you still need two callbacks - one to save the selected columns, and one to plot the data.
