Making data plots

Hi.


Would the "copy" command be useful to you? You can designate a group as the target.

Subject: Making data plots


Folks:
I’ve been working on an app that plots various kinds of data. 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.

The dictionary has some entries on creating groups, but I can’t find anything 
about adding a single object to a group. 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?

Also, I am assuming that if I delete a group, all of the objects in it are also 
deleted.

Best,
Bill
