Hi,
I’m currently working on Ignition 8.3.0. The report was originally developed in Ignition 8.1.48 using MySQL for historical data logging. In that setup, data retrieval worked correctly, and all values were fetched as expected.
After the client upgraded the system to 8.3.0, I updated the configuration to use the Local Core Historian instead of MySQL. Data logging is working properly (verified through the Historical Trend).
However, I’m facing a reporting issue:
Whenever I change the sample size or time range for data retrieval, the columns in the generated report shift or swap randomly.
For example:
-
AIT-D201-DOis the first tag/column -
AIT-D201-TEMis the second tag
But in the generated report, their logged values sometimes swap places between the two columns. This happens inconsistently, only when the date range or sample interval is changed.
I’m attaching a screenshot of the generated report showing the swapped columns.
Has anyone faced this issue in Ignition 8.3 reporting with Local Historian?
Is there any known fix, configuration change, or workaround for this behavior?
Regards,
Iftekhar
