When you want to insert a chart into a document, you can do this. Take a document that has been written in Word, and insert the chart.
Go to Insert Menu – Choose Object, then the Microsoft Worksheet. You can toggle on the document to switch from a graph or a chart of the numbers. Because it is a worksheet inside of the document, you can double click on it and make any changes to the number or whether it is viewed as a spreadsheet or a graph.
In Open office, it would seem that you first have to have the spreadsheet made to insert. You copy the cells you want and then paste them into the document. You can make changes to any of the numbers in the document. I can't seem to get the graph to show up in the Open Office however that can make changes. I can import it as a picture, but not as a changing piece. This might be something I am missing, but it is the first time that Microsoft Office has been better than Open Office.
