TimeSeriesChart - Update Rate

Working with a TimeSeriesChart. I have data being being stored to local Edge Historian. Polled at 500ms.

Trying to put this data in a TimeSeriesChart. I can get the data in there, but the chart is not updating very consistently. I have it being polled every 1s. But only updates on my view every 8s then 3s, then 7s.

What am i mssing on the settings of the chart or the tag?

I have two plots with the same setup for the historical tags.
