Normally, I can make a plot and save it as a .fig file. Then, when I open it later, it will open and show just "Figure 1" in the title bar. Then I can use the command "hold on" to plot other things on that same graph.
On a few of my recent graphs, I had to open the Figure Properties to change some line sizes and I saved those figures in the same way. Now, when I open those figures, the title bar says "Figures - Figure 1" and when I use hold on, it makes a new graph.
It seems like I must have somehow opened these differently somehow, but I have no idea why hold on wouldn't work in the same way, or what I did. Can anyone offer an idea of how to get my figures to open up as JUST the single figure so that I can use hold again?
