U r teaching is superb I learnt app designing very easily thanks

[@polskaa2012]

You are amazing. Thank you!

Hello, your tutorial was helpful. I have a small question, let's say if I have only one button "1", but I have two text fields. Based on which text field my cursor is pointing, Is it possible to display 1 on pointed text field ? (out of two text fields)

Hi, thanks for the tutorial. Instead of passing 'm' value, can you please explain/show how I can pass and plot a user-specified data array for plotting. Basically, I have multiple data arrays (let's say from input u1,u2,u3 to output y1,y2,y3) and each time I run my GUI I want to choose the data set (for example, u1 vs y2 or u2 vs y3 etc.) for plotting. Should I use drop-down or list box for selecting my data sets?

[@BenitoSebastian]

Hi Hakan, Thanks for commenting.You can do this in many ways. You can use a drop down list, use buttons or radio buttons. A drop down list would look very neat and you can simply do an if statement to plot different data sets depending on the selected value in the drop down list. For example: if app.DropDown.Value == "u1vy2" plot(u1,y2) if next condition plot(u2,y2) else if next condition plot(u3,y3) end All the best!

Hi I wrote the same code but still make an error in plot(app.UIAxes,y) Too many input arguments I use auto fill, so iam Sure about spilling And there is no same name of built in function plot

[@csanadtemesvari9251]

try to use plot(app.UIAxes, x, y), it worked for me.

[@akramhussennayem8644]

i do the same thing but when i run the app, too many argument error was shown.How can i overcome this problem

[@BenitoSebastian]

Hi Akram, Make sure you are using the correct syntax. I suggest double checking the capitals, so for example .Value should have a capital V and so on. All the best!

I want to make a OFDM model by using app designer. can anyone help me with this

Select existing callback function does not appear on mines.

[@BenitoSebastian]

Do you have a callback defined that you would like to reuse?

[@theone3746]

@@BenitoSebastian Yes. I followed everything you did.

[@csanadtemesvari9251]

@@theone3746 If you click on the widget, and then go to the coponent browser, on the bottom, you'll see Inspector and Callback. If you click Callback, there'll be a dropdown menu, where you can select existing callbacks.

[@dipto8825]

@@theone3746 Looks Like I am having the same issue. Did you solve it?

[@willingoYT]

Summary: Instead of clicking on a ui object and adding a callback, right click it in the component browser on the right and choose "select existing callback" to set its callback to another used one.
