[Resolved]Having trouble getting Historic trends to work

I'm trying to display historic tag data on an XY Chart.

I found this thread.

[Question] XYChart with Tag History

Thanks a lot. One more question: is queryHistory function something you have defined in gateway scripts (not included in demo project files)? Copy/Paste of the function could be helpful too.

I tried adding the project linked in that post to my Ignition 8 install but it was corrupted. I assume it is just too old to restore to the current Ignition Beta.

I've tried various property bindings as well as I understand the post I linked but I can't get it to work. I bound the datasource property on the control and then it says "No Series Properly Configured".

I went down to the series properties and it has another datasource property. I tried binding that to the datasource property on the control. I also tried binding it directly to the tag history. I tried putting full tag paths in my series. I tried aliases. Everything I try just gives me that error.

I'm assuming I'm doing something wrong but I'm having trouble finding the information I need to fix it.

I forgot I had gotten a good answer on this question before and got called away on a few other things and forgot.

If anyone is having trouble getting this to work; you want this thread.

[Bug-12673] Perspective XY Chart Datasource Update Question

The documentation for this area is not completed. Even the UI for tag history was just implemented a few days ago. Here’s a simple rundown to at least get something on screen. It’s pretty much what Phil said, but with some pictures to help. Bind to the “example” data source. It should look something like this if binding to only one tag’s history. After you do this, your XY chart should look mostly blank because it is not configured to handle the data coming in. [simpleExample] Change the…

The thing I was doing wrong is I was binding my data source to the datasource property on the control and you actually want to bind it to the "example" sub-property on the datasource property.
