Put array in ListBox to choose different values for plot/ App Designer

Hi,

I want to put all these values in the array G into my ListBox, but it doesn't show up.

My array "zR" has different sizes.

My purpose for the ListBox is to choose a number and show in my plot different lines. I am also open to other solutions besides the ListBox for my purpose.

Thank you in advance !

app.ListBox.Items=num2str(zR)
app.ListBox.ItemsData=num2str(zR)

Hello,

No need to assign ItemsData. Try this

app.ListBox.Items=num2str(zR(:))

Hello,

thank you for you answer, unfortunately I got this error.

"Error using matlab.ui.control.internal.model.AbstractStateComponent/set.Items (line 184)'Items' must be a 1-D cell array of character vectors or a string array."

Is there another solution ?

As mentioned in the error 'Items' must be a 1-D cell array of character vectors or a string array.

Try this

app.ListBox.Items = mat2cell(a(:), ones(size(a)), 1)

It appears an error after entering your suggestion:

"Error using matlab.ui.control.internal.model.AbstractStateComponent/set.Items (line 184)

'Items' must be a 1-D cell array of character vectors or a string array."

I figured the solution for my problem:

app.ListBox.Items = num2cell(num2str(zR),2)

Anyway thank you for your help !
