Differences in multi-year-charts set vs etmodel charts set.

[kaskranenburgQ]

Within the multi-year-charts (myc) chart set we support a subset of the graphs we support in the ETModel chart set.
However, not all myc charts have an ETM counterpart.
Below is an overview of the myc charts and their ETM counterpart:

MYC	ETM	Remartk
Final demand (energetic & non-energetic) By sector	x	ETM has Final energy demand per sector (energetic)
Final demand (energetic & non-energetic) By carrier	x	ETM splits up energetic & non energetic in 2 graphs
Final demand (energetic & non-energetic) By sector and carrier	Final energy demand (energetic + non-energetic)	in myc this is not a graph
Final demand (energetic & non-energetic) Agriculture	Final energy demand in agriculture	No non energetic demand for agriculture?
Final demand (energetic & non-energetic) Buildings	x	ETM has Final energy demand in buildings per application
Final demand (energetic & non-energetic) International transport	Final energy demand for international transport per carrier
Final demand (energetic & non-energetic) Energy and other sector	x	ETM has Final energy demand in other sector
Final demand (energetic & non-energetic) Households	x	ETM ETM has Final energy demand in households per application
Final demand (energetic & non-energetic) Industry	x	ETM has mekko for split per subsector : Final energy demand in industry (energetic + non-energetic)
Final demand (energetic & non-energetic) Transport	x	ETM has alot of graphs for transport, but none for an overview
Primary Co2 emissions	CO2 emissions
Renewables	Renewable electricity	ETM expresses in percentages, myc in absolute units

From this overview, we can see that alot of the graphs we support in MYC have an equal chart in the ETM.
This makes it harder to maintain these charts. In addition, there are a lot of barcharts & beziers in the ETM that do not have an equivalent in the MYC.
For me this raises the following discussion points:

• 1. Do we want to support all MYC charts in the ETM as well?
  I find it a bit hard to understand why we would have charts that we deem necessary for the MYC, but not necessary for the ETM.
• 2. Do we want to support all ETM charts in the MYC as well?
  I can understand that not all ETM charts are necessary for the MYC interface, however, if we already support and maintain them in the ETM, we could more easily ( in terms of queries) implement them in the MYC.

@kndehaan perhaps we could discuss this issue on the Modeller sprint to see if we can make it actionable?
