The set_plot_xlabel and set_plot_ylabel routines can add, remove, or change the axis labels:

chips> set_plot_xlabel(r"Wavelength (\AA)")
chips> set_plot_ylabel("Count rate (s^{-1})")

For labels which contain a \ character it is safest to precede the string with a r, as shown in the x-label line above. An alternative is to use \\ instead of \.

To remove a label use an empty string - e.g. set_plot_ylabel("").

More information on these commands can be found using ahelp set_plot.

If you have the CIAO scripts package installed (available from the Scripts page) then you can also use the xlabel and ylabel routines from the chips_contrib.utils module:

chips> from chips_contrib.utils import *
chips> xlabel("Energy (keV)")
chips> ylabel("Counts")

The ChIPS GUI

The ChIPS GUI makes it easy to modify a visualization using your mouse, rather than Python functions. The GUI can also be used to add annotations - such as labels, lines, points and regions - and to zoom or pan into plots.
