Chart widget question

[David Epstein]

Using LC 10 dp2, I am trying to script the creation of a chart widget.  

My command “create widget myName as chart in group myMain” creates only a small gray box.  

The LC command “New Widget/Chart” creates a line chart, ready to be modified.  What is the LC command doing that I am not?

Or:  how do I find the script that LC runs when the “New Widget/Chart” command is chosen?
