Add circles scale to legend

[greboul]

Hi Jolars,
Sorry to ask again another feature but is it possible to add the scale into the legend.
As my circles are going from 1 to 1377 and sometimes crossing only for small amount, if I add the quantities it is unreadable.
I provided you an example here :

Or if you can suggest an other way to be able to see as much as possible the information for datasets like mine.
Thanks a lot in advance !

Hm, I'm principally opposed to that. The idea is that the sizes are proportional across the panels. You will confused viewers if the areas in the different panels mean different things. Scaling the diagrams wouldn't fix the issues with the left and rightmost diagrams anyway. Do you really need the quantity labels?

Perhaps this could be added as an option in the future but for now I think you could achieve what you want by doing something like

p1 <- plot(fit[[1]])
p2 <- plot(fit[[2]])
gridExtra::grid.arrange(p1, p2)

I think I wasn't clear enough because I agree with you about having proportional sizes across the pannel.
The only think I was asking is a scale in the shared legend as this one from ggplot for example :

Sorry, now I understand. That's a good idea and I'll see what I can do; but don't expect anything soon.
