Indirectly addressing "UPPER BOUND" for Easy Chart Axes

I would like to be able to dynamically change the upper and lower bounds of my Easy Chart Axes based on what instrument the operator is viewing.

In the property editor for the easy chart, under “Chart configuration”, there’s a dataset for the Axes. From there, I’m attempting to bind my tag using the cell update binding.

After selecting “UPPER BOUND” cell, I clicked the green “+”. Under “value”, when I enter the following tag value, everything appears to work properly:
{[default]PLC1NAME/INSTRUMENTs/FIC101/PV_MaxScale}

However, I’d like to use indirection but can’t seem to get the syntax right.
Here’s what isn’t working: {[default]PLC1NAME/INSTRUMENTs/FIC{Root Container.INSTRUMENTATION_ID}/PV_MaxScale}

I’m using indirection in several locations throughout the project successfully, but can’t seem to get this one cell to update properly.

Make a custom property and put the indirect binding on that.
Then use that property in the cell update.

Thanks! I was trying to over complicate it. I had a pv indicator on the same faceplate and after reading your response, the lightbulb went off. I tied the binding to the high scale of the indicator and it works as intended.
