Usually in the command window this kind of stuff with the other ocx will open an autocomplete browser. But not for MSChart.

Hmmm. I just tried this with a sample form from one of my sessions that uses MsGraph to generate graphs. I ran the form and grabbed a refgerence to the chart like so in the command window:

o = _screen.activeForm.oGraph.Object

and when I type o. in the command wondow, intelliSense kicked in just fine for me...
