jan_blaha. ~toJS worked! Thank you!

I am also experiencing the same thing.

Check my sample report: https://playground.jsreport.net/w/aquater08/2Dtg2~r9
Replace the binding with the same value from the data template to see the difference.

Background: The value of the every element should be [y, x]. However, when binding the data, the array becomes a single array [y].

Is there a workaround for this?

Thanks.
