Why am I not getting a plot in app designer?

Hi! :)

In my apps, tester_app_2 leads to tester_app3.

There I have to choose salts. I have shortened my program so that it is easier for you people to help me; it is just possible to choose two combinations of salts when you have the possibility to choose salts , either you can choose CaCl MgCl2 ZnBr2 or NaCl KCl ZnBr2.

Then I do what the program instructs me to do, and push on Done, then if I have chosen 2 zones I repeat the procedure for the second zone by clicking on choose zone 2 salts.

The problem is that when I have done this and whatever I am instructed to do afterwards and then push on 'display all results', I dont get any plot showing all results..that is supposed to appear right beneath the table showing all results.

Thanks for helping me, :)

Hi Muazma

I downloaded and tried to run the "test_app_2.mlapp" in MATLAB R2023b, but upon clikcing the "Start analysis" button, I receive the following error in the MATLAB command window.

Unrecognized function or variable 'sett_temperatur'.

Error in beregn_maks_vektprosent_lost_1 (line 62)

temperatur=sett_temperatur();

This error indicates that the "sett_temperatur" function is not defined. I searched for the "sett_temperatur" definition of this function in the shared ZIP file but could not locate it.

This might be a potential cause for the issue faced by you. I'd suggest you to make sure that the functions used in the MLAPP are defined and available on the MATLAB search path, and ensure there are no errors in the MATLAB command window while using the application.

Hope this helps!
