 Overview
-========================
-
+========
 PlotSerializer also provides the functionality of converting the JSON file back into a diagram.
 Only serialized attributes can influence the deserialized plot,
 the created graph might thus look slightly different from the original, the data however will remain unchanged.

 How PloSe sees diagrams
-================================
+=======================
 PloSe uses its own data model for representing scientific diagrams.
 The data model was designed as a general representation of scientific diagrams.
 The base class for this data model is ``plot_serializer.model.Figure``.

 Using Serializer object vs. matplotlib.pyplot
-------------------------------------------
+---------------------------------------------
 So far the Serializer class for Matplotlib only supports the subplots and show method, meaning any other operations on the pyplot object will not get serialized and making
 such changes to your plot still requires calling the functions on the pyplot object. The reason for this being that the Serializer was not implemented as a fully functional proxy 
 for the pyplot object like the AxesProxy class is for Axes of matplotlib.axes.
