Is it possible to read a table props data binding via scripting?

Hello all,

Is it possible to read a table's props.data binding path via script?

I am working on a historical tag chart to read from one tag at a time with the click of a button. The reason is I found some tags were not recording history after migrating from MySql to SQL Server AND my script in another project seems to write tag values offset -1, meaning Tag 1 gets Tag 2's value, for about 27 tags.

So I would like to basically scroll through each tag, from two separate folders, and present their values in a chart. This would help me see what historical values are being recorded.

I figured I could create custom props bound to each tag then just change the table.props.data to the next custom.prop in the list, but to determine the next in line, I need to know which one is currently bound to the table.

Any ideas?

Not live. Perspective doesn't expose its binding machinery the way Vision does. You can inspect the view definition JSON on the filesystem, though.

I thought so. I tried to access the path via:

self.parent.parent.getChild("Table").props.data['binding']['config']['path']

Does the same thing apply to Time Series Charts?

All bindings in Perspective.
