This forked version of plot2svg will be renamed to fig2svg (https://github.com/kupiqu/fig2svg) when ready. Please see work in progress here: https://github.com/kupiqu/fig2svg/blob/master/README.md

Scalable Vector Graphics (SVG) Export of Figures

Converts 2D & 3D Matlab plots to the scalable vector format (SVG). This format is specified by W3C (http://www.w3.org) and can be viewed and printed with internet browsers.

Added preliminary support of filter, clipping, and tickmark extensions that go beyond the Matlab functionality. SVG filters are a great tool to create stylish plots! Try it out! Before you start using this new features have a look at the tutorial. More information and examples can be found on my blog http://www.zhinst.com/blogs/schwizer/.

Tested browsers and editors for basic SVG support (no filters, no animation): Opera 9.64, 10.50, 10.63 -> yes Firefox 3.5, 3.6, 12.0, 15.0 -> yes Inkscape 0.46, 0.47, 0.48 -> yes Chrome 8.0, 18.0, 21.0 -> yes Internet Explorer 9.0 beta -> yes Internet Explorer 8.0 -> no Internet Explorer + RENESIS -> yes

Tested browsers and editors for SVG filters: Opera 9.64, 10.50, 10.63 -> yes Firefox 3.5, 3.6, 12.0, 15.0 -> yes Inkscape 0.46, 0.47, 0.48 -> yes (some limitations) Chrome 8.0, 18.0, 21.0 -> yes Internet Explorer 8.0, 9.0 beta -> no Internet Explorer + RENESIS -> no

Editors for the SVG file format can be found at http://www.inkscape.org.

Usage:

plot2svg % opens a file dialog to plot the active figure or plot2svg('myfile.svg', figure handle, pixelfiletype)

pixelfiletype = 'png' (default), 'jpg'

How to use SVG files in HTML code

Changes in Version 22-May-2005

  • bugfix line color
  • bugfix path of linked jpeg figures
  • improved patch handling (interpolation and texture still missing, preliminary depth sorting)
  • support of pcolor plots
  • preliminary: surface plots are projected on the xy-plane (use 'rotate' command)

Changes in Version 12-Dec-2005

  • bugfix viewBox
  • improvement of the axis scaling (many thanks to Bill Denney)
  • improvement handling of exponents for log-plots
  • default pixel format png instead of jpeg (many thanks to Bill Denney)
  • bugfix axindex
  • bugfix cell array cells (many thanks to Bill Denney)
  • improved handling of pixel images (many thanks to Bill Denney)
  • to save original figure background use set(gcf,'InvertHardcopy','off')
  • improved markers

Changes in Version 8-Jan-2006

  • axes handling fully reworked (3D axes)
  • rework of axes scaling (3D axes)
  • clipping enabled (Use carefully, as all figure data is written to file -> may get large)
  • minor grid lines are now supported for linear and log plots
  • linear color interpolation on patches (The interploation needs to be emulated as SVG does not support a linear interpolation of colors between three points. This is done by combination of different patches with linear alpha gradients. See limitation for Firefox 1.5.)

Changes in Version 20-Jun-2009

  • Bugfix '°','±','µ','²','³','Œ''œ','Ÿ','©''®'
  • Bugfix 'projection' in hggroup and hgtransform
  • Added Octave functionality (thanks to Jakob Malm) Bugfixe cdatamapping (thanks to Tom) Bugfix image data writing (thanks to Tom) Patches includes now markers as well (needed for 'scatter' plots (thanks to Phil)
  • Bugfix markers for Octave (thanks to Jakob Malm)
  • Bugfix image scaling and orientation Bugfix correct backslash (thanks to Jason Merril)
  • Improvment of image handling (still some remaining issues) Fix for -. line style (thanks to Ritesh Sood)

  • Line style scaling with line width (will not match with png output)
  • Small optimizations for the text base line
