how to keep plotting commands in the main guide if more than one is available ?

hello,

so i am having a gui with some code lets call that main gui and i am having other gui with other code and lets call that second gui, i made a button in the main gui so that when the user presses it it opens the second gui and this is working perfectly but my problem is that in the second gui i have some data and i have already extracted them and placed them in a global that is available in both gui the main and the second so that the data can appear on the first gui specifically here when i am trying to input commands for plotting in the button that opens the second gui instead of plotting them in the main axis which is in the main gui it plots them in the second i hope somebody understands what i mean. Thanks in advance.
