Bind an XY Chart dataSource to ../

Ignition 8.0.0 seems to be buggy when the XY Chart has its Tag History date range changed rapidly / often. The Table component does not suffer this problem.

Is it possible to have the XY Chart bind to the …/ and use that instead of another Historian binding? When I try it I get the Perspective Property Editor warning

dataSources.example: string found, array, dataset expected.

As a matter of interest, if this idea worked would this decrease server load because the dataset only has to be generated once?

I’ve set the table data binding to return the history in Document format.
In Designer I can examine the data under dataSources/example/0, etc. and it all looks fine.
