.. py:class:: Widget_graphsVisualLite(theGraphs, **kwargs)


   Bases: :py:obj:`PyQt5.QtWidgets.QWidget`

   Widget element to draw a graph. The traces and graphs to draw are defined in :class:`~optimeed.visualize.graphs.Graphs.Graphs` taken as argument.
   This widget is linked to the excellent third-party library pyqtgraph, under MIT license

   .. py:attribute:: signal_must_update

      

   .. py:attribute:: signal_graph_changed

      

   .. py:method:: set_graph_disposition(indexGraph, row=1, col=1, rowspan=1, colspan=1)

      Change the graphs disposition.

      :param indexGraph: index of the graph to change
      :param row: row where to place the graph
      :param col: column where to place the graph
      :param rowspan: number of rows across which the graph spans
      :param colspan: number of columns across which the graph spans
      :return:


   .. py:method:: __create_graph(idGraph)


   .. py:method:: __check_graphs()


   .. py:method:: on_click(plotDataItem, clicked_points)


   .. py:method:: update_graphs(singleUpdate=True)

      This method is used to update the graph. This is fast but NOT safe (especially when working with threads).
      To limit the risks, please use self.signal_must_update.emit() instead.

      :param singleUpdate: if set to False, the graph will periodically refres each self.refreshtime


   .. py:method:: fast_update()

      Use this method to update the graph in a fast way. NOT THREAD SAFE.


   .. py:method:: select_folder_and_export()


   .. py:method:: exportGraphs(filename)

      Export the graphs


   .. py:method:: export_txt(filename_txt)


   .. py:method:: export_svg(filename)


   .. py:method:: export_tikz(foldername_tikz)


   .. py:method:: link_axes()


   .. py:method:: get_graph(idGraph) -> optimeed.visualize.graphs.graphVisual.GraphVisual

      Get corresponding :class:`~optimeed.visualize.gui.widgets.graphsVisualWidget.GraphVisual.GraphVisual` of the graph idGraph


   .. py:method:: get_trace(idGraph, idTrace) -> optimeed.visualize.graphs.traceVisual.TraceVisual

      Get corresponding Tracevisual


   .. py:method:: keyPressEvent(event)

      What happens if a key is pressed.
      R: reset the axes to their default value


   .. py:method:: delete_graph(idGraph)

      Delete the graph idGraph


   .. py:method:: delete()


   .. py:method:: get_all_graphsVisual()

      Return a dictionary {idGraph: :class:`~optimeed.visualize.gui.widgets.graphsVisualWidget.GraphVisual.GraphVisual`}.


   .. py:method:: get_layout_buttons()

      Get the QGraphicsLayout where it's possible to add buttons, etc.


   .. py:method:: set_actionOnClick(theActionOnClick)

      Action to perform when the graph is clicked

      :param theActionOnClick: :class:`on_graph_click_interface`
      :return:


   .. py:method:: set_title(idGraph, titleName, **kwargs)

      Set title of the graph

      :param idGraph: id of the graph
      :param titleName: title to set



.. py:class:: Widget_graphsVisual(*args, **kwargs)


   Bases: :py:obj:`Widget_graphsVisualLite`

   Create a gui for pyqtgraph with trace selection options, export and action on clic choices

   .. py:method:: refreshTraceList()

      Refresh all the traces


   .. py:method:: set_actions_on_click(actions)
