I couldn't see a theme element that would allow you to modify that via opts(), but you could go lower-level and edit the appropriate rect grobs. Having produced the plot ... ggplot(diamonds, aes(clarity, fill=color,colour = cut)) + geom_bar(position = dodge) ... you could inspect grid.ls() output by eye to see which grobs these are likely to be and do something like ... grid.gedit(gPath(GRID.cellGrob.439, legend.frame, GRID.cellGrob, key.gTree, GRID.rect), gp=gpar(fill=white)) ... but the 439 will change each time you produce the plot (it will almost certainly be a different number for you) so could automate somewhat by using grid.ls() to determine the *second* GRID.cellgrob directly beneath the legends grob ... grobList - grid.ls() secondLegend - grep(legends::GRID.cellGrob.[0-9]+$, grobList$gPath)[2] grobName - grobList$name[secondLegend - 1] grid.gedit(gPath(grobName, legend.frame, GRID.cellGrob, key.gTree, GRID.rect), gp=gpar(fill=white)) ... which should work (for your plot) every time you draw it. Is that the result you were after? Paul Does anyone know how to rule that?

[R] ggplot bar geom: control the filling in the colour legend
Hi all, Is it possible to change the filling of the squares used to represent the colour legend in a bar plot with ggplot? in this example, fillings are raven black, I'd like them white. ggplot(diamonds, aes(clarity, colour = cut)) + geom_bar() Regards -- - Benoit Boulinguiez Ph.D student Ecole de Chimie de Rennes (ENSCR) Bureau 1.20 Equipe CIP UMR CNRS 6226 Sciences Chimiques de Rennes Avenue du Général Leclerc CS 50837 35708 Rennes CEDEX 7 Tel 33 (0)2 23 23 80 83 Fax 33 (0)2 23 23 81 20 http://www.ensc-rennes.fr/ __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Sure, just change the color of the fill. ggplot(diamonds, aes(clarity, colour = cut)) + geom_bar(fill=white) -Ista On Fri, Sep 10, 2010 at 2:24 PM, Benoit Boulinguiez benoit.boulingu...@ensc-rennes.fr wrote: Hi all, Is it possible to change the filling of the squares used to represent the colour legend in a bar plot with ggplot? in this example, fillings are raven black, I'd like them white. ggplot(diamonds, aes(clarity, colour = cut)) + geom_bar() Regards -- - Benoit Boulinguiez Ph.D student Ecole de Chimie de Rennes (ENSCR) Bureau 1.20 Equipe CIP UMR CNRS 6226 Sciences Chimiques de Rennes Avenue du Général Leclerc CS 50837 35708 Rennes CEDEX 7 Tel 33 (0)2 23 23 80 83 Fax 33 (0)2 23 23 81 20 http://www.ensc-rennes.fr/ __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. -- Ista Zahn Graduate student University of Rochester Department of Clinical and Social Psychology http://yourpsyche.org __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
