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 …/Table.props.data 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?
Update:
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.
