Tag data disappears when trying to graph it

Ignition
1

Hello! I am attempting to graph a tag's data in realtime using perspective's time series line chart and it seems that the tag data disappears when I try to graph it.

I followed the steps from the Time Series Chart lesson on ignition university which are:

  1. Create a line time series component
  2. Bind the data property of the series property and select the tag that should be graphed.
  3. Press okay and the graph loads the tag's realtime data.

I'm not sure what I am doing wrong since the video was pretty straight forward. Here is some photos to give more context

This is my binding setup. I have a single series called realtime tag data and have selected the [edge]IO/CT301_AI tag to graph

The data viewer shows theres no data, but the tag certainly has data (as seen in the tag browser)

Please let me know if there is anymore info I can provide. Thank you!

The tag in your last screenshot doesn't have history enabled.

@PGriffith Hmm, I am trying with another tag (FT101) and I've made sure that it's history is enabled, but it's still not showing up in the graph. Could something be wrong with my historian? I am using ignition edge

Figured it out. To graph realtime tag data, you must enable history (as @PGriffith said above) and make sure that the tag's storage provider (under History in the tag editor) is not none

I’ve been hit with that several times. Might be a nice feature request that you get a pop up reminding you that you haven’t selected a storage provider.
