**u2.51.02** Plotting curves with Code_Aster
=============================================

**Summary:**

This document explains how, from a calculation result, one can produce tables or functions, extract the values from these tables or functions, manipulate them, and finally use the print commands to draw curves.

If you have a function or a table and you simply want to represent it as a curve, go directly to paragraph [§ :ref:`4 <Ref101086366>`], and consult the documentation for commands IMPR_FONCTION [:external:ref:`U4.33.01 <U4.33.01>`] and IMPR_TABLE [:external:ref:`U4.91.03 <U4.91.03>`].

**Preliminary note**

*Post-processing should be done in* *POURSUITEet not as a result of the calculation. Several reasons for this:*


1. *in case* of error*, we do not lose the hours of calculation that made it possible to reach the* result *,*


2. we can perform numerous post-treatments directly by launching Stanley based on the result of the calculation (see astk [:ref:`U1.04.00 <U1.04.00>`] or *STANLEY* [:external:ref:`U4.81.31 <U4.81.31>`]),


3. *to simplify post-processing, we can use the possibilities offered by Python that require being in* *PAR_LOT =' NON 'in* *POURSUITEce which prevents the use of eficas for this type of post-processing, while it is easier to use eficas to build the main dataset.*
