I’m trying to pull data out of a PI historical system to use in a perspective Time Series or XY Chart. I’m having a hard time getting it cooperate since I can’t browse the HDA sources under the tag history tab on the bindings.
What I did manage to do was make use the system.tag.queryTagHistory command with the HDA provider and got a dataset back that was like 500 rows and 2 columns (Timestamp and value great news!). I thought I was off to a good start so I built a generic script you feed the PI tag path back and it pulls the history into a dataset.
Then I went to bind this to the time series chart and was met with an error…The dataset pulls in correctly but I was met with a blank chart and my dataset example object was changed into a value:Dataset[2108x2]. So now my question is: How do you bind datasets to play nicely with the new perspective charts?
Can I also request a feature to add HDA browsing back to the Tag History binding like in vision?
