Hello,

Suggestion: Add a built-in script function for deleting historian data

Title

Add system.historian.deleteDataPoints() as the counterpart to system.historian.storeDataPoints()

Problem

Ignition allows us to add history through system.historian.storeDataPoints(), but there is no built-in way to delete or prune specific data points. If data is inserted incorrectly (wrong type, test values, corrupted entries), the only current options are manual database edits or full partition pruning, which are risky and not practical.

Proposed Solution

Introduce a built-in function such as:

system.historian.deleteDataPoints(

paths,

startDate=None,

endDate=None,

timestamps=None

)

This would allow safe cleanup of historian data for specific tags and time ranges, with optional dryRun and auditing for transparency.

Why It Matters

Symmetry with storeDataPoints()

Safer than direct SQL or partition pruning

Helps maintain data quality

Useful for automation and maintenance

Thank you for considering this improvement.
