Hello to All Prime Expert

I am having another MatchCAD Prime issues. Plotting simple equation in MatchCAD 15 worked. After transfer to Prime the graph - Plotting failed. Replace complex values and NaN by real numbers.

I can't see any issues here. 

Please help.

You have to define a range for x with correct units.

As Fred already showed you have to define a range in Prime if you want to use values with units at the abscissa.

Real Mathcad (MC15 and below) actually differs in that respect as it would not force you define a range.
Keep in mind that when you define a range with units, you must provide a second value (you cant define x:=0m..30m).
Its not that obvious, but in Prime you can also change the values and steps at each axis. Its a bit tricky because of the small font size, but you can change/retype the first, second and last value on each axis.
