ChIPS was removed from CIAO in the CIAO 4.12 release, with plotting now handled by Matplotlib.
Please see the ChIPS to Matplotlib conversion guide and contact the CXC Helpdesk if more help is needed.
How do I add or change the plot title?
The set_plot_title routine can add, remove, or change the plot title:
chips> set_plot_title(r"Best fit: \color{red}\alpha = 2.3 \pm 0.2")
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 the title use an empty string - e.g. set_plot_title("").
More information on this command 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 title routine from the chips_contrib.utils module:
chips> from chips_contrib.utils import * chips> title("Model profile")
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.
