Why ? The text entry is in KChart, so KChart knows the range, so it
can fetch the data from KSpread, right ? So the only thing you need,
make it so the KSpread broadcasts all changes to KChart, which will
then be determining whether it's a change of interest and react
accordingly. Maybe a bit difficult, but I really don't see any sense
in having KSpread know about KChart - it's a plugin, it's supposed to
be separated :)
