I use pA y axis and ms x axis. What is the unit of area given by the area function?
Igor does not look at the units and try to interpret them. It just takes them as they are so the results will 'pA'*'ms' where I used single quotes to emphasize they are just two letters and have no other meaning. Had you used A and s as units with the values scaled to pico and milli, then the results would be in A*s with a exponent in the vicinity of 10^-16. For example:

•make ydata={0,1E-12};
•SetScale y,0,0,"A", ydata
•SetScale/I x,0,1e-3,"s",ydata
•display ydata
•print area(ydata)
  5e-16


Note that the axes will be properly labeled in pA and ms.

The units for the area printout are A*s.
