Bugs: contour_* routines
Bugs
The contour_* routines cannot be used if 'set_coord("world")'
The contour_* routines cannot be used if 'set_coord("world")' has been set. The following error is printed out when any of the contour_* routines are called in this case (see the full list of contour routines by typing "contour*?" at the Sherpa prompt):
sherpa In [12]: set_coord('world')
sherpa In [13]: contour('data')
NotImplementedErr: contours on non-uniform grids are not yet supported
The image (logical) and physical coordinate system settings are unaffected by this bug, but note that after changing to the world coordinate the contour routines will result in errors eventhow the first time the contours were plotted.
sherpa In [6]: set_coord('world')
sherpa In [7]: contour('data')
NotImplementedErr: contours on non-uniform grids are not yet supported
sherpa In [8]: set_coord('logical')
sherpa In [9]: contour('data')
NotImplementedErr: contours on non-uniform grids are not yet supported
sherpa In [10]: set_coord('physical')
sherpa In [11]: contour('data')
NotImplementedErr: contours on non-uniform grids are not yet supported
