class Data(x: list, y: list, x_label='', y_label='', legend='', is_scattered=False, transfo_x=lambda selfData, x: x, transfo_y=lambda selfData, y: y, xlim=None, ylim=None, permutations=None, sort_output=False, color=None, symbol='o', symbolsize=8, fillsymbol=True, outlinesymbol=1.8, linestyle='-', width=2)

This class is used to store informations necessary to plot a 2D graph. It has to be combined with a gui to be useful (ex. pyqtgraph)

set_data(self, x: list, y: list)

Overwrites current datapoints with new set

get_x(self)

Get x coordinates of datapoints

get_symbolsize(self)

Get size of the symbols

symbol_isfilled(self)

Check if symbols has to be filled or not

get_symbolOutline(self)

Get color factor of outline of symbols

get_length_data(self)

Get number of points

get_xlim(self)

Get x limits of viewbox

get_ylim(self)

Get y limits of viewbox

get_y(self)

Get y coordinates of datapoints

get_color(self)

Get color of the line

get_width(self)

Get width of the line

get_number_of_points(self)

Get number of points

get_plot_data(self)

Call this method to get the x and y coordinates of the points that have to be displayed. => After transformation, and after permutations.

Returns:x (list), y (list)

get_permutations(self)

Return the transformation ‘permutation’: xplot[i] = xdata[permutation[i]]

get_invert_permutations(self)

Return the inverse of permutations: xdata[i] = xplot[revert[i]]

get_dataIndex_from_graphIndex(self, index_graph_point)

From an index given in graph, recovers the index of the data.

Parameters:index_graph_point – Index in the graph Returns:index of the data

get_dataIndices_from_graphIndices(self, index_graph_point_list)

Same as get_dataIndex_from_graphIndex but with a list in entry. Can (?) improve performances for huge dataset.

Parameters:index_graph_point_list – List of Index in the graph Returns:List of index of the data

get_graphIndex_from_dataIndex(self, index_data)

From an index given in the data, recovers the index of the graph.

Parameters:index_data – Index in the data Returns:index of the graph

get_graphIndices_from_dataIndices(self, index_data_list)

Same as get_graphIndex_from_dataIndex but with a list in entry. Can (?) improve performances for huge dataset.

Parameters:index_data_list – List of Index in the data Returns:List of index of the graph

set_permutations(self, permutations)

Set permutations between datapoints of the trace

Parameters:permutations – list of indices to plot (example: [0, 2, 1] means that the first point will be plotted, then the third, then the second one)

get_x_label(self)

Get x label of the trace

get_y_label(self)

Get y label of the trace

get_legend(self)

Get name of the trace

get_symbol(self)

Get symbol

add_point(self, x, y)

Add point(s) to trace (inputs can be list or numeral)

delete_point(self, index_point)

Delete a point from the datapoints

is_scattered(self)

Delete a point from the datapoints

set_indices_points_to_plot(self, indices)

Set indices points to plot

get_indices_points_to_plot(self)

Get indices points to plot

get_linestyle(self)

Get linestyle

__str__(self)

export_str(self)

Method to save the points constituting the trace

class Graph
