co­ordsys – Draw carte­sian co­or­di­nate sys­tems

The pack­age pro­vides com­mands for type­set­ting num­ber lines (co­or­di­nate axes), co­or­di­nate sys­tems and grids in the pic­ture en­vi­ron­ment.
The pack­age may be in­te­grated with other draw­ing mech­a­nisms: the doc­u­men­ta­tion shows ex­am­ples of draw­ing graphs (co­or­di­nate ta­bles cre­ated by Maple), us­ing the eepic pack­age's draw­ing ca­pa­bil­i­ties.
