I designed a gui that allows the user to pick a data file using uigetfile and one of the functionalities is the data is plotted. I would like the user to have the option to plot additional data on the same plot. I added a check box on the gui for the user to indicate they would like to select an additional file to plot, while the checkbox is clicked. All the code within my gui is under a pushbutton callback function. Is there a way to "re-run" the pushbutton callback function (with or without selecting the pushbutton again)? The only thing I need is for the data to keep being plotted on the same graph for as many times the user wants.
