Viewers#
Jdaviz provides specialized viewers for different types of astronomical data.
Creating Viewers#
By default, viewers are created automatically based on the data format you load:
import jdaviz
jdaviz.show()
# Automatically creates appropriate viewer
jdaviz.load('spectrum.fits', format='1D Spectrum')
You can also create viewers programmatically:
# Create a new viewer
viewer_creator = jdaviz.viewers['1D Spectrum']
new_viewer = viewer_creator()
See the individual viewer pages for detailed usage information.
UI Access#
Control data and subset layer order and visibility for each viewer. Toggle layer visibility, reorder layers by dragging, and manage which data appears in the viewer.
dm = jd.viewers[viewer].data_menu
Data Menus#
Each viewer has a legend in the top-right indicating what layers are currently displayed. Clicking on the legend opens a data menu where you can: - Toggle visibility of individual layers - Remove layers from the viewer - Rename viewers
For more information, see Data Menu.
Plot Options#
Changing viewer or layer options is done through the Plot Options plugin in the settings sidebar.
