Is there a native scripting function or otherwise a way to supply a tagpath and get returned its historical path

What do you mean by historical tag path?

I am not an expert here, but I don’t think that’s a “correct” term. Tag history doesn’t get stored in a tag, so there should be no historical tag path. (I could be wrong). Tag history gets stored in a database via the historian.

What exactly are you trying to do?

something that looks like so…  
histprov:BM\_CX:/drv:ma-ign-io-a1:default:/tag:flr\_0/erb02/batty/tm\_ups\_1a\_1/temp\_01\_c

Like what the tag tree provides in the powerchart

But why? Like for a report, alarm, store in another tag, like what’s your end game? If you had it, what would you be doing with it?

[system.tag.getConfiguration()](https://docs.inductiveautomation.com/display/DOC81/system.tag.getConfiguration) is what you want, but you will need to construct the path.

i am adding-on to the ad-hoc chart... I am just constructing the string... but idk it isnt working.. i thought maybe it had to be lowercase... because that is the source path the tree generates a lowercase string.. But i am scripting my pen objects and they look just like the ones i drag and drop from the tree..

I was looking at this but tagHistoryPath or what ever we shall call it isnt a prop of a tag?

Probably a better way to build it, but I have used this before, `pyData` is a list of tag paths

```auto
for row in pyData:
	prov = re.search(r"(?<=\[).+?(?=\])",str(row['Tag'])).group()
	tag = re.sub(r"\[[^()]*\]", "", str(row['Tag']))
	alarm = row['Alarm']
	sourcePath = 'prov:'+prov+':/tag:'+tag+':/alm:'+alarm

```

Edit, to clarify, `pyData` is the results from a table with columns ‘Tag’, ‘Alarm’.

I am doing this more or less… I am looking for a baked in method…

</div>

```auto
from com.inductiveautomation.ignition.common import QualifiedPath, WellKnownPathTypes

qp = QualifiedPath.Builder()
	.set(WellKnownPathTypes.HistoryProvider, "provider")
	.setDriver("driver")
	.setTag("path/to/tag")
	.build()
	.toString()

```

Doesn’t really buy you much over joining the string parts together yourself.
