Thanks Wai. But what I found was that as I change the time period in the top left for the graph to longer or shorter, it changes the granularity of the measurements, and the magnitude of the bars changes. There is some sort of aggregation going on?
Yes there is some sort of aggregation when we do charting.
Hm....I am not quite sure what is the best way, maybe API call to return a list of response time time-series-data in JSON format can help in this case, but better let somebody from Dynatrace to answer that.
