Option to use previous poll's data instead of "No Data"
In the case of JDBC collection, there are many times when a query runs long due to load on the DB and is killed by LM according to the configured timeout. This action is appropriate but the resulting "No Data" is mostly undesirable. In the "If there is no data for this datapoint" dropdown, I would like to see an option for "Use Previous Data". I know in many instances, "No Data" is a really bad thing but, in others, it is not. Instead of breaking all my dashboard widgets and seeing "NaN" in raw data, I would prefer seeing a limited amount of old data. 1-3 polling cycles would be a reasonable length of substitution before returning to "No Data" or "not a number" results.
