If you'd like to completely translate Export plugin, you may want to create a separate language file, include it and set a language setting for chart.
However, if you'd like to just customize a single or several prompts in Export menu, you can do so by modifying default English translation, like this:
AmCharts.translations[ "export" ][ "en" ][ "menu.label.undo" ] = "Undooo"; AmCharts.translations[ "export" ][ "en" ][ "menu.label.redo" ] = "Redooo";
Please note that this code needs before the chart code.
Below is the complete list of customizable textual prompts (with their default text) that you can override this way:
"fallback.save.text": "CTRL + C to copy the data into the clipboard."
"fallback.save.image": "Rightclick -> Save picture as... to save the image."
