plot(title=None, channels='all', area=None, scale='linear', vmin=None, vmax=None, zscale=False, colorbar=None, **kargs)[source]¶ Plot the raw images.
Parameters: title : str
Figure title (None by default).
channels : list or ‘all’
list of channel names. All by default.
area : list
list of pixels
[pmin,pmax,qmin,qmax]to zoom.scale : str
‘linear’ | ‘log’ | ‘sqrt’ | ‘arcsinh’ | ‘power’ The stretch function to use for the scaling (default is ‘linear’).
vmin : float
Minimum pixel value to use for the scaling. If None, vmin is set to min of data.
vmax : float
Maximum pixel value to use for the scaling. If None, vmax is set to max of data.
zscale : bool
If true, vmin and vmax are computed using the IRAF zscale algorithm.
colorbar : str
If ‘h’/’v’, a horizontal/vertical colorbar is added.
kargs : dict
kargs can be used to set additional Artist properties.
