How to edit a saved png file

Hi All, I generated some graphs and saved as png. After a review a need change something like label and titles, but I don't want to re-run my tests to get my graphs again(I also would get a different chart and it is something that I don't want to). I just need to edit my saved graphs as .png file. Is it possible? If it is, can someone help me out? Thanks

Well, if the only thing you are going to change is labels and titles or texts on legends, then I guess you are better off with photo-editing tools like MS paint or Photoshop. I think it is possible to edit it afterwards if you saved it as .fig but I don't think you can open a png and make it back to a matlab figure and edit it.

OK, so next time is it better to save my graph as fig file? If it is, once I have a .fig file how can I open/edit? Thanks

You can try this to edit with a GUI

Or you can try this to change things in code
