How to write around a circle in inkscape manual

Sampling of Axes methods and the Artist instances they create Below is a simple Python script illustrating the architecture above. It defines the backend, connects a Figure to it, uses the array library numpy to create 10, normally distributed random numbers, and plots a histogram of these.

Import the FigureCanvas from the backend of your choice and attach the Figure artist to it. Here "" means create bins. For everyday purposes, particularly for interactive exploratory work by bench scientists who are not professional programmers, it is a bit syntactically heavy.

Most special-purpose languages for data analysis and visualization provide a lighter scripting interface to simplify common tasks, and matplotlib does so as well in its matplotlib. The same code above, using pyplot, reads import matplotlib. A histogram created using pyplot pyplot is a stateful interface that handles much of the boilerplate for creating figures and axes and connecting them to the backend of your choice, and maintains module-level internal data structures representing the current figure and axes to which to direct plotting commands.

Let's dissect the important lines in the script to see how this internal state is managed. When the pyplot module is loaded, it parses a local configuration file in which the user states, among many other things, their preference for a default backend.

This might be a user interface backend like QtAgg, in which case the script above will import the GUI framework and launch a Qt window with the plot embedded, or it might be a pure image backend like Agg, in which case the script will generate the hard-copy output and exit.

This is the first plotting command in the script. If so, it will extract the current Axes and direct plotting to the Axes. In this case there is none, so it will create a Figure and Axes, set these as current, and direct the plotting to Axes.

As above, pyplot will look to see if there is a current Figure and Axes. Finding that there is, it will not create new instances but will direct the call to the existing Axes instance method Axes.

This will force the Figure to render, and if the user has indicated a default GUI backend in their configuration file, will start the GUI mainloop and raise any figures created to the screen. A somewhat stripped-down and simplified version of pyplot's frequently used line plotting function matplotlib.

All other pyplot scripting interface functions follow the same design.

1 The Dongle Problem

This allows us to forward them on to the corresponding API method. Thus the pyplot interface is a fairly thin wrapper around the core Artist API which tries to avoid as much code duplication as possible by exposing the API function, call signature and docstring in the scripting interface with a minimal amount of boilerplate code.

Backend Refactoring Over time, the drawing API of the output backends grew a large number of methods, including: Since each of the backends was implemented by a single developer who was expert in a particular output file format, it sometimes took a long time for a new feature to arrive in all of the backends, causing confusion for the user about which features were available where.

For matplotlib version 0. The number of required methods in the backend API was reduced considerably, to only: This interfaces replaces many of the old methods: Draws text with the given font properties.

Given a string of text, return its metrics. It's possible to implement all of the drawing necessary for a new backend using only these methods. This is useful for getting a new backend up and running more easily. However, in some cases, a backend may want to override the behavior of the core in order to create more efficient output.

For example, when drawing markers small symbols used to indicate the vertices in a line plotit is more space-efficient to write the marker's shape only once to the file, and then repeat it as a "stamp" everywhere it is used. If it's implemented, the backend writes out the marker shape once and then writes out a much shorter command to reuse it in a number of locations.

The full list of optional backend API methods is: Draws a set of markers. Draws a collection of paths. Draws a quadrilateral mesh.The above code specifies a red oval inscribed in a yellow rectangle. One of the most flexible of SVG's primitive objects is the path.

uses a series of lines, splines (either cubic or quadratic), and elliptical arcs to define arbitrarily complex curves that combine smooth or jagged transitions.

Differences from previous versions. GRUB 2 is a rewrite of GRUB (see History), although it shares many characteristics with the previous version, now known as GRUB of GRUB Legacy may need some guidance to find their way around this new version.
