Methods Documentation

change_units(x, y=None, z=None)

Change the displayed units

Parameters:

• x (units) – The new units for the dispersion
• y (units) – The new units for the flux
• z (units) – The new units for the multi-spectral dimension.

static from_layer(layer, **kwargs)

Create a LinePlot from a layer

Parameters:

• layer (Spectrum1DRefLayer) – The layer to create from.
• kwargs (dict) – Other arguments for LinePlot class.

Returns:

The new LinePlot

Return type:

plot_container

set_error_visibility(show=None)

Show the error/uncertainty

Parameters:show (bool) – If True, show the error/uncertainty info.

set_line_width(width)

Set the line plot width

Parameters:width (float) – The width of the line

set_mode(mode)

Set the line plotting mode

Parameters:mode ('line' | 'scatter | 'histogram') – The plot mode

set_plot_visibility(show=None, inactive=None)

Set visibility and active state

Parameters:

• show (bool) – If True, show the plot
• inactive (bool) – If True, set plot style to indicate this is not the active plot.

update(autoscale=False)

Refresh the plot

Parameters:autoscale (bool) – If True, rescale the plot to match the data.
