You can change the appearance of the axes in the following ways:
1. Press
b4 and choose the Zoom tool to use.
2. Select the axes and press
/b3 to activate the Attributes tool.
a) Press 9 or : to move to the attribute to change. For example,
choose the end style attribute.
b) Press 7 or 8 to choose the style to apply.
c) Change any other attributes of the axes as required for your work,
then press

3. Adjust the axes scale and tic mark spacing manually.
a) Click and hold one tick mark, and move it on the axis. The spacing
and number of tic marks increases (or decreases) on both axes.
b) To adjust the scale and tic mark spacing on a single axis, press and
hold
g, and then grab and drag a tic mark on that axis.
4. Change axis end values by double-clicking them and typing new
values.
5. Adjust the location of the axes. To move the existing axes without
resizing or rescaling them, click in and drag an empty region of the
screen until the axes are in the desired location.
6. Change the axes’ scales by pressing b41.
Type the values of your choice over the current values for x-min,
x-max, y-min, and y-max and click
OK.
7. Press b21 to hide or show the axes.
