Plot Workbench/cs

Introduction
FreeCAD is able to perform plots using the matplotlib Python library. A module is provided to this end, as an external add-on in version 0.19 and as a core component from version 0.20 on. Older versions of FreeCAD are not covered in this documentation.

The produced plots offer the standard matplotlib tools to edit and save. On top of that, a Plot Workbench is provided as an external add-on offering more complete tools to edit the plot and save it. The add-on can be installed with the Add-on manager.

Module
The module can be invoked in a Python console or in a macro. The first thing you must do is importing the module. In FreeCAD 0.19 you must first install the Plot Workbench using the Add-on manager, and then you can import Plot by typing:

From FreeCAD 0.20 on plot module is already packaged within the program, so you don't need to install any add-on, but just type

After that, you can plot a straight line from (0,0) to (1,2) just simply typing

You can find more complex examples in the Plot Basic tutorial and the Plot MultiAxes tutorial.

Workbench Tools
If you decide to install the Plot Workbench using the Add-on manager, you will have the following tools available to manage the plots created with the module:


 * [[Image:Plot_Save.svg|32px]] Save plot: Saves the plot in several formats. You can select the output size and resolution too.
 * [[Image:Plot_Axes.svg|32px]] Axes: Add, remove or edit plot axes.
 * [[Image:Plot_Series.svg|32px]] Series: Edit series title and styling.
 * [[Image:Plot_Grid.svg|32px]] Grid: Show/hide grid.
 * [[Image:Plot_Legend.svg|32px]] Legend: Show/hide legend.
 * [[Image:Plot_Labels.svg|32px]] Labels: Edit labels.
 * [[Image:Plot_Positions.svg|32px]] Positions: Set elements positions.

Scripting
Since Plot module is a layer over matplotlib, you are free to use all matplotlib commands over plot instances. See scripting examples section to see examples.
