Excel 2007

Hello Michael
Thank you for your question

If you have just pasted the chart in from excel into word then click on the chart in Word once. You should see some small black squares appear in the corners of the chart. Hover the mouse over these until they change to arrows, click and drag the chart to make it larger or smaller.

If this resolves your question, please mark it as resolved. If not, please reply with more information.

Kind regards
Cress
