I have a wpf graph control that shows a series of plots that are associated to some Y Axis. Sometimes (not for every collection of plots) when I click on the top value of an y-axis scale (it allows me to change the value) and insert a new value, it throws an Invalid Operation Exception. In other cases, the scale and the plots associated to the it are correctly rescaled.
I didn't notice particular differences between the cases in which the error occurs and the cases in which everything works.
The part of StackTrace that regards NationalInstruments libraries is the following:
Exception: System.InvalidOperationException
