plotting to subplots in gui using handles from created plots

hello, i wrote a code that gets a .txt file and from the data creates several plots. to each plot i assigned a handle. i have a gui with 4 subplots, i want to be able to plot on the subplots the plot from the code. it wont be always on the same subplot. can i do that, or should i make the plotting from the callback function it self?

thanks for the help.
