grafana: include storage dispatch in market results by technology plot

[gugrimm]

Would be helpful to extend the query to show storage dispatch

[mthede]

would you like to have the storage consumption, demand, exchange dispatches as well? so e.g. all demands with negative signs:

likewise would be the storage dispatches in both directions (don't have storage in my current simulation, so would look a bit like this but added on top of the other volumes):

[gugrimm]

yes, of course exchanges would also be nice.
I was not sure if we want to include charging and demand, as the plot is entitled "dispatch", I saw it as "only positive". But would in my opinion add value if it contained everything!

[mthede]

We could surely split it into two plots (generation/dispatch/... vs. consumption/demand/load/...). But I do like, esp. for storage units, if it's inside one plot and you can see the charging and discharging periods alternating. Let's ask the team in 25mins what's preferred and intuitive.
