Plot-O-Matic now has an “undo” button. Here’s how it works:

• Every time you save, change graphs, or create or delete something, a ‘save point’ is created.
• You can use the back/forward buttons to move between ‘save points’.
• You can see what ‘save point’ you’re at by looking at the address bar. It’s the part after the ’#’ sign, and will be something like save_1 or save_32.
• If you are using FireFox, then the history will be saved if you go to another page and then back.
• If you are using Internet Explorer, the history will be lost if you go to another page and then back. I’m working on fixing this.

Please note that this is not (yet!) a true undo: if you delete a graph or graph line or data column, you can’t undelete by hitting the back key.
