N. Custom Plot Symbols

GMT comes with several custom plot symbols ready to go. They are used in psxy and psxyz using the -Sk option. To make your own custom plot symbol, please follow the instructions given in the man pages of those two programs. The following is a plot of each symbol. Note that we only show the symbol outline and not any fill. Be aware that some symbols may have a hardwired fill or no-fill component. Also note that some symbols, in particular the geometric ones, appears to duplicate what is already available as built-in symbols. However, the custom symbols differ in that they may be filled with patterns.
