Superset "dummy" metric

[#1]

Hi,

I want to have a time series chart and display each value without aggregation. Superset requires a metric. How can I create a metric without aggregation?

For me the follwoing aggregation is working:

[{ "type" : "doubleMax" , "name" : "dummy_value", "fieldName" : "original_value" }]
