Binding tag history to an Easy Chart

I’m not sure if this is a bug or whether I’m doing something incorrectly.
I am trying to bind ‘tag history’ of a number of SQL Tags into the tag pens of an easy chart so that I can use the easy charts functionality.
When I try to add a tag depending on the number of data points within the time range, the same number of identical pens are added to the easy chart.

Many Thanks

This is actually working correctly. You are not able to create a tag history binding on the tag pens property of the easy chart. You should drag and drop the tags onto the chart. Once you do that you can look at the tag pens dataset to see what it returns.
