Nina,
In MS Word, you have 2 options when you select Insert Object:
Microsoft Excel Chart
Microsoft Graph 2000 Graph
If you select Insert Picture, you can choose Chart. This is the same chart as when you select Microsoft Excel Chart.
To insert this chart, you will use Word Insert Graph.vi. This VI calls Word_Insert_Chart.vi, that uses ADO object Graph.Chart and its properties and methods.
From the Microsoft Help:
Create a chart by using Microsoft Graph
When you create a chart by using Microsoft Graph, a chart and its associated data are displayed in a table called a "datasheet."
