Hi, I want to be able create a pie chart using rails, does anyone know of any plugin''s taht could help me here? Scott -- Posted via http://www.ruby-forum.com/.

We regularly get questions about making pie charts, and frequently veer off into the philosophical and practical issues surrounding that form of data graphic: human perception of angles and so on. So while this isn't an R issue, I thought some of you might appreciate this brief discussion of the efficacy of pie charts: http://fakescience.tumblr.com/post/6042293374/understanding-pie-charts

Dear all, After going through the Lattice doc and R-help list and google, I got the feeling that there is no function in lattice or other package to compute a pie chart object of class "trellis". Although pie charts are obviously not considered optimal even in the pie() doc ;-) , pie chart trellis objects would be easy positioned e.g. over a map drawn with the grids package. Can

You may want to rethink your whole approach here: 1. Pie charts are usually a poor choice of graph, there are better choices. 2. Adding percentages to a pie chart is a way of admitting that the pie chart is not doing the job. 3. If you want people to compare percentages, then a table is what is needed. 4. A pie chart with percentages added is essentially a colorful but poorly layed out table.

Hi there! I have seen that someone had this question some years before, but there was only a rough answer to it and I was wondering if actually someone was able to accomplish it or maybe even wrote a function... How do you make a bubble plot where you have pie charts instead of bubbles? I have a geographic map and need to plot attribute-sized pie charts representing a second attribute at

Hi, I have a vector of data, that I group based on two factors via tapply. For each such grouping I would like to plot a pie chart. I can layout these pie charts in a matrix layout, correpsonding to the levels of the two factors. But I am getting stuck on how to label the rows and colums. My current approach looks like this: x <- data.frame(obs=sample(c('low', 'high'),100,

Hey, i'd like to compose a clock-like looking plot composed out of two circles, each showing the length of a period (to compare them). first, to do so, it looked the easiest by using pie(), just puting multiple pie-charts over each other. the problem is that once the second pie is drawn, it replaces the first one. does anybody know how to add a second, smaller pie over an existing one,

dear R-community, Is it possible to have one pie chart of a large radius and then a pie chart with smaller radius placed on top of the larger so the centers of the two pie charts coincide? I managed to place a filled circle with smaller radius in the piechart, see below. Thanks in advance, Sybille pie(rep(1,12), col=rainbow(24), radius=0.9, labels=

Hi , I am looking to making a panel of pie charts fo some of my dritribution data . I was wondering if there is a way in any R package to write a small script to do so. Thanks, Amin [[alternative HTML version deleted]]

Hey R'rs, So im sick of dealing with ESRI products and am looking to stream line a process i now use GIS to do using R. I have made a lot of maps using R but have not yet seen a map that puts pie charts within the map to help represent data like the attachment. http://r.789695.n4.nabble.com/file/n2318816/template1.bmp I found Tanimura et al. work "Proportional Symbol Mapping in

Dear R-Community. I am trying show pie charts on a graph. To be precise, I have series of catch calues by species by geographic (5 deg by 5 deg) regions. I want to draw circles (actually pie charts showing the proportion of the catch in each area) so that I have a graph of catch by species by geographic area! I know there is the < symbols(dat$lon,dat$lat,circles = dat$sp1, add=TRUE) > but

I am having trouble finding out how to adjust the position of labels on pie charts. For the small wedges, many of the labels overlap making it impossible to read. Is there any way to offset the labels so that they don't overlap? Adam Green USGS Patuxent Wildlife Research Center [[alternative HTML version deleted]]

Hi, despite the fact that pie charts often fail, I'll draw them anyway (in a case were they are not fail ;-) ). Does anybody know a package/methods which can draw pie of pie or bar of pie charts similar to that in MS Excel? -- Kind regards, Mathias

Have you read the books by Cleveland? His experiments show that most people do better estimating things and comparing things on a linear scale rather than looking at angles and areas (also see http://biostat.mc.vanderbilt.edu/twiki/pub/Main/StatGraphCourse/graphsco urse.pdf) With a dot chart you can set the axis to go from 0 to the total of all groups (see the example I sent before, it could

Hi All, I'm trying to find out a way to plot multi-panel pie charts. It may not be the best way to present data, but I would still need one. 1. Is anyone aware of some in-built script/function which can do this for me. I'm aware of one given in Deepayan's book, but anything apart from this? 2. I tried using Deepayan's script on following data set but it doesn't seem to work

Dear R user group, I wish to plot small pie-charts to specific coordinates in a e.g. scatter-plot: E.g.: > plot(rnorm(100),rnorm(100)) > points(1,1,col="red",cex=4) -> I wish to put pie(c(2,3)) at the position of the red circle... How can I do this efficiently? Thanking you and wishing you a wonderful Sunday! Georg. ************************** Georg Ehret Johns Hopkins

Hi all, I've a problem with the size of the labels of my pie-charts when I try to write them to a postscript file. I need to increase the default size, so I change cex (see below). On screen this works fine, but cex doesn't seem to affect the postscript-file. Any suggestions? Thanks a lot, Daniel Copy/Past-example (will try to write to c:/temp!): labels <- c("I",

Hi, I have reconstructed ancestral character states on a phylogeny using MuSSE in the diversitree package and plotted the character state probabilities as pie charts on the nodes. I would, however, like to colour the character states of my extant species, i.e. the tip labels, the same colours as my pie charts, such that all species in state 1 are e.g. blue, species in state 2 red and species in
