Assume x coordinate in column 1, y coordinate in column 2

#Define a convenient function
#Note: NaN means "not a number",  the program will skip these values
#
limit( column, maxvalue ) = column > maxvalue ? NaN : column 

plot 'file1' using (limit($1,XMAX1)):(limit($2,YMAX1)), \
     'file2' using (limit($1,XMAX2)):(limit($2,YMAX2)), \
     'file3' ...
