Making data plots

[Mark Schonewille]

Hi Bill,

The dictionary entry about the create command contains the in group 
clause. Example:

create button "New Button" in group "Old Group"
put it into myLongID

When you delete the group, all its objects are also deleted.

For some of the data, where I need a line plot, I create lines, boxes, labels, etc, and after they are displayed, I take a snapshot of the graphic and then delete the objects that I used to create the plot. So far, as a beginning live coder, I’ve just stored the names of the graphic elements of the plot in an array, then deleted them using the array entries. But, it seems, as the plots are getting more complex, that it might be easier or more efficient to put the objects for a single plot into a group, then I can delete the entire group in one operation.

I want to do this so that each time an element of the plot is created, it is added to the group. That way, I don’t have to keep track of the objects myself. Is there a tutorial where I can find this information?
