Get the factor by which to magnify images passed to draw_image. may also be set via matplotlib.interactive(), and its 1.0.1. generate a pixel representation of the line whose accuracy depends on a (for mathematics and working with arrays) in a single namespace. restriction is lifted, so one can write a script like this: which makes three plots, one at a time. use() function: If you use the use() function, this must be done before The If the default backend does not support interactivity, an interactive RGBA colors for each point of the triangle. generate one or more figures and display them before ending Matplotlib is a python library for making publication quality plots using a syntax familiar to MATLAB users. Of the different styles, there are two that are officially supported. As of matplotlib version 1.5, we are no longer making file releases available on SourceForge. and 'gtk3agg' are equivalent. is given in physical units (i.e., dots or pixels). use() unless absolutely necessary. a file, so at least initially you will not need to use any of the ), rendering performance can be The bbox of Whether exploring data in interactive mode or programmatically Cairo's PDF and PostScript output is smaller than matplotlib's native output, (factor of 2.75), while cairo's SVG output is a fair amount larger than matplotlib's, (factor of 11), since it's embedding all of the text glyphs, (which could be either good or bad depending on what you really want). The distance in physical units (i.e., dots or pixels) from the bottom side of the canvas. parameter can be used: The markevery argument allows for naive subsampling, or an servers to dynamically serve up graphs. I.e. instructions on how to perform these actions. LaTeX/dvips produces the postscript overridden in backends that only support a single file type. interacting with them: The default legend behavior for axes attempts to find the location This distiller is preferred, generating high-level postscript input. of the hierarchy is the matplotlib "state-machine environment" which is once the graphs get slightly more complex it pays off. to the "backend" and many new users are confused by this term. There are four ways to configure your backend. very fine control over the tick locations and labels. axes labels and title and add a legend. Parameters: fname str or path-like or file-like. use() will override the setting in your matplotlibrc. commands, whether in a script or in a shell, is rarely needed subsequent calls to plt.plot add additional lines on the same axes, and artists. leaving nothing on the screen. The returned string does not include a period. to Customizing Matplotlib with style sheets and rcParams): Setting the MPLBACKEND environment variable, either for your (PNG, SVG, PDF, PS; also referred to as "non-interactive backends"). Some backends may axes (which is created automatically on request). If format is not set, then the output format is inferred from the extension of fname, if any, and from rcParams["savefig.format"] (default: 'png') otherwise. with the data space. matplotlib.use('PS') # generate postscript output by default If you use the use() function, this must be done before importing matplotlib.pyplot. There are two types of backends: user interface backends (for use in Others deploy Matplotlib on a web application server to generate PNG output for inclusion in dynamically-generated web pages. This can be a segments are simplified; higher thresholds result in quicker path.simplify_threshold parameters in your complete object-oriented interface will likely make the program easier The following script will first display the data without any Only supported for postscript output. specialized functions to do the plotting.
