You've still not bothered to mention which version of the program you're
using or what method was used to create the chart. Without that information
this is just a guess: I'm *assuming* this is in Word 2008 & that you're
dealing with a Smart Art chart object. If that's the case you have at least
three options:
1- Control/Right-Click the Chart Area & select Edit in Excel, or
2- Control/Right-Click the Plot area of the chart & select Edit Data, or
3- Click the Edit in Excel button in the Chart Data group of the Formatting
Palette
