One of the commands in the Margins and World menus of the Picture window.
To view and change the current world coordinates of the horizontal and vertical axes.
The axes are normally changed by every drawing operation in the dynamic menu, i.e., by object-specific drawing commands with titles like Draw... and Paint... (the drawing commands in the Picture window, like Paint rectangle..., do not change the axes).
You would use the Axes... command if your data are not in an object.
The following script would draw a person's vowel triangle:
# Put F1 (between 300 and 800 Hz) along the horizontal axis,
# and F2 (between 600 and 3600 Hz) along the vertical axis.
Axes... 300 800 600 3600
# Draw a rectangle inside the current viewport (selected area),
# with text in the margins, and tick marks in steps of 100 Hz along the F1 axis,
# and in steps of 200 Hz along the F2 axis.
Draw inner box
Text top... no Dani\e"l's Dutch vowel triangle
Text bottom... yes %F_1 (Hz)
Text left... yes %F_2 (Hz)
Marks bottom every... 1 100 yes yes yes
Marks left every... 1 200 yes yes yes
# Draw large phonetic symbols at the vowel points.
Text special... 340 Centre 688 Half Times 24 0 u
Text special... 481 Centre 1195 Half Times 24 0 \o/
This example would draw the texts "Daniël's Dutch vowel triangle", "F1 (Hz)", and "F2 (Hz)" in the margins, and the texts "u" and "ø" at the appropriate positions inside the drawing area.
