Problem:
Now, if I put graph prototype into screen template, then I can get graphs (for each item of prototype). It is very difficult for complex screens design and usability.

Feature request for graph prototypes:
I would like to have graph prototype for all items of one discovery item in one graph.
For example,
for prototype item "vfs.fs.size[{#FSNAME},pfree]" I would like to see one graph window with data of all disks free spaces.
May be, during adding item prototype into graph prototype add option single/all.
