How To Install Pycairo Examples

Conclusion Graphite is an incredible tool: easy to install, fast and flexible. Since its creation in 2006 it has seen the development of many plugins and tools.

But it is getting a bit outdated by the next generation of monitoring tools, such as the trendy, which promise more flexibility and scalability. The problem with graphite: it’s easy to monitor, but you need to spend your time watching all metrics to spot malfunctions.

Pycairo is a Python module providing bindings for the cairo graphics library. It depends on cairo >= 1.13.1 and works with Python 2.7+ as well as Python 3.4+. Pycairo, including this documentation, is licensed under the LGPLv2.1 as well as the MPLv1.1. For the life of me I can't figure out how to install cairo on Windows! I need it for Haskell Charts, but when I follow setup instructions and get to running: cabal install gtk I get this error: Linking dist/setup-wrapper setup.exe.

CairoPlot is an API written in and uses to plot 8 kinds of graphics: horizontal and vertical bars, scatter, dots and lines and functions plots. Pie and donut plots and Gantt Charts. It was born on an attempt to plot graphics in a more beautiful way, making it possible to use them on presentations, websites and papers. The project is now 2 years old and many have helped through e-mails, bugs and code.

Special thanks to Jo達o S. Bueno, Magnun Leno, Mike Rooney, Chris Ward, Karel Kolman, Victor Westman and Tim Swast. To see what CairoPlot is capable of, visit the but if you want to see what's new on version 1.2, check the session.

Also, you can use the menu on the left to navigate through all the tutorials available on the site. Installation Installation tutorials cover the files needed to install and use CairoPlot on each of the three Operational Systems available today. Data handling Explanations on how to input data to CairoPlot. Basic use Basic use tutorials explain how to input data to create each one of the graphics available on CairoPlot. Data objects are used to hold any primitive data along with its name. • Numbers integers, floats or long values.• Points represented as 2 (x,y) or 3 (x,y,z) items tuples; if a user inputs a list, it's automaticaly converted to a tuple.

Examples d = Data(name='empty') print d #prints empty: () d = Data((1,1),'point a') print d #prints point a: (1, 1) d = Data((1,2,3),'point b') print d #prints point b: (1, 2, 3) d = Data([2,3],'point c') print d #point c: (2, 3) d = Data(12, 'simple value') print d #prints simple value: 12. Groups are used to hold data objects, defining indepedent series of values. Users might fill a group object in a variety of ways: • Numbers or points Saved as a new data object.• List or tuple of numbers or points Each number is converted to a data object and added to a new list, which will be held on the group.• Two or three lists of coordinates Sometimes, it's easier to just input all coordinates as series not as points.

The group object zips them and saves them as points.• Data object or a data objects list Both saved directly on the group. All graphics in CairoPlot might be generated using one of two ways: defining an object or calling a function. #Defining a new object data = [[1,2,3],[4,5,6],[7,8,9]] test = cairoplot.HorizontalBarPlot('object_way.svg', data, 640, 480) test.render() test.commit() #Calling a function data = [[1,2,3],[4,5,6],[7,8,9]] test = cairoplot.horizontal_bar_plot('function_way.svg', data, 640, 480) The arguments of the functions are, exactly, the same as the ones from the classes' __init__ methods, and that's why only the former will be detailed on the next sections.

But, as all classes inherit data from the Plot class, many of these arguments would be repeated if explained on each class, that's why they are detailed below. Surface Default value: None A filename or a Cairo surface.

For filenames, CairoPlot supports svg, png, pdf and ps extensions. Examples: 'test.svg', 'test.png', 'test.pdf', 'test.ps' data Default value: None A series, group or data object is expected.
