Hi Everyone, Can anyone tell me how to draw a bar chart in Rails? Is there any in-built method in Ruby on Rails (or) should i go for 3rd party plugins? I searched and came across this "open flash chart" - i don''t know how to customize it according to my requirement. PS: I have attached my requirement sample for you reference. Thanks, Vasanth Attachments:

Hey, I need to make a radar chart (also called spider chart, star chart) and am trying to see if there is a plugin for this. GchartRB looked good, but I don''t see Radar Charts on here: http://gchartrb.rubyforge.org/ Does anyone know a good plugin or gem that will generate radar charts? tl;dr, Joe -- Posted via http://www.ruby-forum.com/.

Well, I''m trying to generate graphs using gruff, but I''m having problemns. I use, require_gem ''gruff'' then when I run g = Gruff::Line.new(475) I get uninitialized constant Gruff ///// c:/ruby/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_support/dependencies.rb:100:in `const_missing''

Hi, I am using "gruff" lib for creating the graphs. I have got the success to create the graph, but my problem is I don''t want to store it, I want that they should be displyed on the browser it self. I have tried this:- " send_data(g.to_blob, :disposition => ''inline'', :type => ''image/png'', :filename =>

I''ve been working with Gruff to do all my apps graphing and such etc. I love it but I''m just having a hard time customizing the graphs, but this is perhaps due to my inability to comprehend the online RDocs. What I want to do is adjust the width / heights of my graphs or at the VERY LEAST the heights. It seems that if you scale a graph anywhere below 400-450px it is pretty

I have some graphs and everything is working great, but I''d like to set a minimum height so to speak on the vertical scale. Is there a method to do that with Gruff? I''ve tried looking through the docs but can''t seem to get it to work. So for example, if the highest datapoint in my graph was say 500, is it possible to have the minimum vertical scale on the left set

Hi R Users, I have a dataframe like this: id x rho A 1 0.1 B 20 0.5 C 2 0.9 ... I want to do a scatter plot of "x" versus "rho" but for each point on the scatter plot I want the corresponding entry for "id" instead of points. In STATA I can do so by twoway (scatter x rho, mlabel(id)) How can I do the same in R? I am sure there is some simple way to do

Hi,   I would like to draw a box at each corner of lower 10% and upper 10% in the scatter plot on(0,1)*(0,1)  to indicate the lower and upper tail.  I hope somebody can help me.   Here is my code: ## scatter plot plot(hume_uni[,2],beec_uni[,2], pch=19, xlab="Hume_uni", ylab="Beec_uni", col= "blue")  title(main="Scatter plot of uniformised data of Hume and

Does anybody know how to adding colors to data points in scatter plot in R? I have the following R data frame - Voter_Name, Education_years, Income, Registered Ricky, 18, 40000, Y Lisa, 20, 34000, N Jon, 10, 35000, Y ... I am doing a scatter plot in R for those data points - Income vs. EducationYears. I would also like to using different colors to differentiate whether that data point is a

Hello, I am working on a project to create some scatter plots. I have syntax for 26 plots, and 22 of them display as they should. But here, for example, is a sample of the command syntax I am using: good <- complete.cases(affect1,adh1scr) plot (jitter(affect1,2.0),jitter(adh1scr,1.0),xlim=c(1,35),ylim=c(1,35),pch=1 6, main='Adherence Score by Affectiveness Level - Visit 1',

Hello: I would like to be able to do a 3D scatter plot from 3 variables, 2 independent and 1 dependent. The closest R function I could find for this is "cloud". However cloud uses, as input, a matrix where the value of each matrix element is the dependent variable value at that matrix coordinate. My problem is that the independent variable values are floating point and can be of

Hello Nabble users, A question about having two y axes on a chart. I'm trying to show on the left (first) y axis a measure used in an experiment; the x axis shows the experiment number, that has been sorted in a specific manner -- i.e. not Experiments 1,2,3,n, but could be Experiment 6,1,18,n; the right (second) y axis shows an experimental variable. The idea of the chart is to show how

Dear All, I am using the following commands to do the scatter plot of two vectors, say X and Y. plot(X,Y, col="blue") abline(a=1,b=1, col="red") abline(a=-1,b=1, col="green") I would like to split the scatter plot into 3 part with 3 different colors: (i) points lies between 2 lines, (ii) points above line 1, and (iii) points below line 2. I am struggling to do

Hi All, I have data for two groups, group with 100 points and group B with 15 points. i needed plot these two groups in one scatter plot, each group with a different color. I tried plot3d(data, col = c("red", "blue")[c(rep(1, 100), rep(2, 15))], pch=20) . this works but the graph does not look good. the other option that I tried is scatterplot3d(data, type="p",

Hello, I am having a strange problem with Gruff not always displaying the graph on the page. On some pages, the graph is displayed fine. On others, however, I just get the number relating to the id of the requested item - in my case, report. Does anyone know how to solve this problem? I have the following in my controller: def create_graph g = Gruff::Line.new(290) g.title =

How to use ggplot to do the binned quantile plots(one type of scatter plot)? Hi all, I have done scatter plot: plot(x, y). Now I wanted to do binned quantile plots... can ggplot2 help me? For example, we bin x data into 10 bins. For each bin, we draw the 10 deciles of the corresponding y data in that bin as points/dots. And then accross all bins, we would like to connect the corresponding

I am doing very regular stuff like the following: attach(wtana) fm<- lm(Body.Wt.on.SD1~Heart.Wt, data=wtana) #fm<- lm(wtana$Body.Wt.on.SD1~wtana$Heart.Wt) lrf<- loess(Body.Wt.on.SD1~Heart.Wt, wtana) #lrf<- loess(wtana$Body.Wt.on.SD1~wtana$Heart.Wt) plot(Body.Wt.on.SD1,Heart.Wt) #plot(wtana$Body.Wt.on.SD1,wtana$Heart.Wt) #lines(spline(Heart.Wt,fitted(lrf)), col=2) abline(fm, col=4)

Dear useRs, I'd like to produce some scatter plots where N units on the X axis are equal to N units on the Y axis (as measured with a ruler, on screen or paper). This approach x <- sample(10:200,40) ; y <- sample(20:100,40) windows(width=max(x),height=max(y)) plot(x,y) is better than plot(x,y) but doesn't solve the problem because of the other parameters (margins etc). Is

Hello, I have created a 3d scatter plot using the plot3d command in the rgl package. I have approximately 6500 data points in the scatter plot. I would like to color these points sequentially using the entire color spectrum. (So the first point is red, next point slightly different, and each point gradually changes so that the final point is violet.) Is anyone familiar with how this can be done?

Hi guys i am pretty much a newbie to rails and tried to install gruff and run the example given in home page for gruff i am using ubuntu and dapper. first i got two errors when i used this example #!/usr/bin/ruby require ''rubygems'' require ''gruff'' g = Gruff::Line.new g.title = "My Graph" g.data("Apples", [1, 2, 3, 4, 4, 3])
