Time Series Chart X Trace not lining up with gridline time label

[mbak]

We've got a time series chart where the X trace time is not lining up with the X trace's hovered data timestamp. The amount that it is off varies as the span of the dataset changes. Sometimes it is right on. This particular time series chart is looking at a numeric entry field to show the last x hours of data on the chart. The chart is updating the timespan when the numeric entry is modified, it's just that the x grid time label has a discrepancy with the timestamp from the x trace.

I've found a couple references to something similar in the forum, but no response on those posts. Any ideas or help is appreciated.

You are mixing "As Stored" results with "Wide" format. It is impossible for the data points to have reliable timestamps with this combination as the historian has to duplicate values into multiple rows.

Use tall format. Group the tall dataset by tag path and produce multiple series for the chart, where each series is just one tag and its actual timestamps.
