spectrochempy.plot_image

plot_image(dataset, *args, **kwargs)[source]

Plot a 2D dataset as an image plot.

Alias of plot_2D (with method argument set to image ).

Parameters:

  • dataset (NDDataset) – The dataset to plot.

  • **kwargs – Optional keyword parameters (see Other Parameters).

Other Parameters:

  • ax (|Axes| instance. Optional) – The axe where to plot. The default is the current axe or to create a new one if is None.

  • clear (bool, optional, default=`True`) – Should we plot on the ax previously used or create a new figure?.

  • figsize (tuple, optional) – The figure size expressed as a tuple (w,h) in inch.

  • fontsize (int, optional) – The font size in pixels, default is 10 (or read from preferences).

  • style (str)

  • autolayout (bool , optional, default=True) – if True, layout will be set automatically.

  • output (str) – A string containing a path to a filename. The output format is deduced from the extension of the filename. If the filename has no extension, the value of the rc parameter savefig.format is used.

  • dpi ([ None | scalar > 0]) – The resolution in dots per inch. If None it will default to the value savefig.dpi in the matplotlibrc file.

  • colorbar

  • transposed

  • clear

  • ax

  • twinx

  • use_plotly (bool, optional) – Should we use plotly instead of mpl for plotting. Default to preferences.use_plotly (default=False)

  • data_only (bool [optional, default=`False`]) – Only the plot is done. No addition of axes or label specifications (current if any or automatic settings are kept.

  • method (str [optional among map , stack , image, surface or 3D]) – The type of plot,

  • projections (bool [optional, default=False])

  • style (str, optional, default=’notebook’) – Matplotlib stylesheet (use available_style to get a list of available styles for plotting

  • reverse (bool or None [optional, default=None) – In principle, coordinates run from left to right, except for wavenumbers (e.g., FTIR spectra) or ppm (e.g., NMR), that spectrochempy will try to guess. But if reverse is set, then this is the setting which will be taken into account.

  • x_reverse (bool or None [optional, default=None)
