- Parameters
errors (list of lists) – A list with lists of fitting errors. A separate CED curve will be rendered for each errors list.
error_range (list of float with length 3, optional) –
Specifies the horizontal axis range, i.e.
error_range[0] = min_error error_range[1] = max_error error_range[2] = error_step
If
None
, then'error_range = [0., 0.101, 0.005]'
.figure_id (object, optional) – The id of the figure to be used.

True
, a new figure is created.title (str, optional) – The figure’s title.
x_label (str, optional) – The label of the horizontal axis.
y_label (str, optional) – The label of the vertical axis.
legend_entries (list of `str or
None
, optional) – If list of str, it must have the same length as errors list and each str will be used to name each curve. IfNone
, the CED curves will be named as ‘Curve %d’.render_lines (bool or list of bool, optional) – If
True
, the line will be rendered. If bool, this value will be used for all curves. If list, a value must be specified for each fitting errors curve, thus it must have the same length as errors.line_colour (colour or list of colour or
None
, optional) –The colour of the lines. If not a list, this value will be used for all curves. If list, a value must be specified for each curve, thus it must have the same length as y_axis. If
None
, the colours will be linearly sampled from jet colormap. Example colour options are{'r', 'g', 'b', 'c', 'm', 'k', 'w'} or (3, ) ndarray
line_style (
{'-', '--', '-.', ':'}
or list of those, optional) – The style of the lines. If not a list, this value will be used for all curves. If list, a value must be specified for each curve, thus it must have the same length as errors.line_width (float or list of float, optional) – The width of the lines. If float, this value will be used for all curves. If list, a value must be specified for each curve, thus it must have the same length as errors.
render_markers (bool or list of bool, optional) – If
True
, the markers will be rendered. If bool, this value will be used for all curves. If list, a value must be specified for each curve, thus it must have the same length as errors.marker_style (marker or list of markers, optional) –
The style of the markers. If not a list, this value will be used for all curves. If list, a value must be specified for each curve, thus it must have the same length as errors. Example marker options
{'.', ',', 'o', 'v', '^', '<', '>', '+', 'x', 'D', 'd', 's', 'p', '*', 'h', 'H', '1', '2', '3', '4', '8'}
marker_size (int or list of int, optional) – The size of the markers in points. If int, this value will be used for all curves. If list, a value must be specified for each curve, thus it must have the same length as errors.
marker_face_colour (colour or list of colour or
None
, optional) –The face (filling) colour of the markers. If not a list, this value will be used for all curves. If list, a value must be specified for each curve, thus it must have the same length as errors. If
None
, the colours will be linearly sampled from jet colormap. Example colour options are{'r', 'g', 'b', 'c', 'm', 'k', 'w'} or (3, ) ndarray
marker_edge_colour (colour or list of colour or
None
, optional) –The edge colour of the markers. If not a list, this value will be used for all curves. If list, a value must be specified for each curve, thus it must have the same length as errors. If
None
, the colours will be linearly sampled from jet colormap. Example colour options are{'r', 'g', 'b', 'c', 'm', 'k', 'w'} or (3, ) ndarray
marker_edge_width (float or list of float, optional) – The width of the markers’ edge. If float, this value will be used for all curves. If list, a value must be specified for each curve, thus it must have the same length as errors.

True
, the legend will be rendered.legend_title (str, optional) – The title of the legend.
legend_font_name (See below, optional) –
