Scales and sizes for plotting frequency characteristics and polar diagrams
This standard specifies the aspect ratios for logarithmic, or level characteristics expressed in decibels, versus a logarithmic frequency axis on a cartesian (x vs. y) axis. Level ranges for polar diagrams are also specified. This standard is applicable to printouts, electronic files, scientific publications, screen displays and graphs in other standards.
