How to store cell array or data in the GUI?

I made a script that read an xls file and put it into a cell array,plot the data from the excel file values and save the figure plot. I am trying to make that script into a simple GUI application. I manage to read the xls file but I don't know how to store variables and use it in the GUI.

Thanks

Use guidata

I have figure it out by using assignin and global. Will that work better if my variable is a cell array and used in for loops?

This is not a good idea. If you don't want to use guidata, you can store your data in userdata of any of your objects

I understand, thank you sir.
