How does KaleidaGraph determine which plot to show in the various cells in the layout?
As plots are added to the layout window, KaleidaGraph maintains a link between the cell in the layout and the position of the plot in the Select Plot submenu. If a particular cell contains the first plot in the list, opening or creating another plot will cause the cell to display this new plot.
Any time you open, create, or close a plot, it is possible for the plots in the layout to change positions because the location of the plots in the Select Plot submenu has changed. For this reason, it is best if you open or create all of your plots before arranging them in the layout window.
When you open a saved standard layout file, the plots are loaded based on the link between the cells and the position of the plots in the Select Plot submenu. If a cell previously held the first plot in the Select Plot submenu, it will display whatever plot is currently first in the submenu.
