get_model_prof_prefs

Synopsis

The plot preferences for radial or elliptical profiles of the model (after any PSF convolution) for imaging data.

get_model_prof_prefs()

Description

The get_model_prof_prefs() command returns the preferences for plots of model values created by the prof_model(), prof_fit(), prof_fit_resid(), and prof_fit_delchi() commands. Changing the values will not change existing plots, only new plots created after the change was made. For example

sherpa> get_model_prof_prefs()["xlog"] = True

will cause any new plots to use logarithmic scaling for the X axis.

Loading the routine

The routine can be loaded into Sherpa by saying:

from sherpa_contrib.profiles import *

Example

sherpa> prof_model()
sherpa> plt.xscale('log')
sherpa> plt.yscale('log')
...
sherpa> prefs = get_model_prof_prefs()
sherpa> prefs["xlog"] = True
sherpa> prefs["ylog"] = True
sherpa> prof_model()

The preferences are set so that both the x and y axes should be drawn using log scaling. Setting the get_model_prof_prefs values only affects plots made after the change; to change an existing plot you need to use Matplotlib commands such as xscale() and yscale().

Bugs

See the bugs pages on the Sherpa website for an up-to-date listing of known bugs.
