legend

I'm currently creating plots in ggplot2 by importing custom images and using them as geom_points, similar to this post , except I am looping through different images for unique levels of a factor. Is there an easy way to add these images to the legend? I've seen multiple posts on custom legends in ggplot2, but nothing that deals with imported images. I'm not sure how you will go about generating your plot, but this shows one method to replace a legend key with an image. It uses grid functions to locate the viewports containing the legend key grobs, and replaces one with the R logo library(png)

Using this example http://matplotlib.org/examples/pie_and_polar_charts/pie_demo_features.html how could I add a legend to this pie chart? My problem is that I have One big slice 88.4%, the second largest slice is 10.6%, and the other slices are 0.7 and 0.3%. The labels around the pie don't appear (except for the biggest slice) and neither the percentage values for the smaller slices. So I guess I can add a legend showing the names and the values. But I haven't found out how... # -*- coding: UTF-8 -*- import matplotlib.pyplot as plt # The slices will be ordered and plotted counter-clockwise.

I wish to substitute the following (yes, I've written it here in TeX format, just to be clear) $P_{M1}(\tilde{z}>z) - P_{M0}(\tilde{z}>z)$ for the green line's legend entry (cptsdtbehavioralm), and $P_{M2}(\tilde{z}>z) - P_{M0}(\tilde{z}>z)$ for the blue line's legend entry (fullbehavioralmodel). Here is the code with which I generated the plot (I am omitting the 10,000-observation dataset and the transforms to generate the functions Fm0, Fm1 and Fm2): bmp("bias_plot_v4.bmp", width=540, pointsize=10) ggplot(data.frame(x=c(0,80)),aes(x) ) + stat_function(fun=function(x)((1-Fm1(x)) - (1- Fm0(x))

I'm using nvd3 and have a few charts where the legend is much to large. E.g. a scatter/bubble with 15 groups and the group names are long. The legend is so large that it leaves almost no room for the chart itself. Is there a way to remove the legend or toggle the legend or limit the height/width it is taking up? Any example would be great. Also, is there a way to have the bubble show a descriptive string? Right now when you stand on top of a bubble it highlights the x/y coordinates. I also want it to show the bubble name. For example, each of my bubbles represents a country (which has a name),

I see a lot of questions regarding how to customize legends, but I can't even get a legend to customize. I would like to have a legend explaining that the black line is quadratic and that the green line is cubic. library(ggplot2) myfun1 <- function(x) x^2 myfun2 <- function(x) x^3 myplot <- ggplot(data = data.frame(x = 1:5, y= 1:5), aes(x=x, y=y)) + stat_function(fun = myfun1, color="green") + stat_function(fun = myfun2, color="black") Try this: ggplot(NULL, aes(x=x, colour = g)) + stat_function(data = data.frame(x = 1:5, g = factor(1)), fun = myfun1) + stat_function(data = data.frame(x = 1:5,

I have a graph use the base graphics package. For the labels on specific points I use text(i, MSSAcar$summary[i,7]+.7, qld$LGA[i], col='red', cex=.7, family='serif') I have also used this in the plot for main titles and axis labels. They all come out as expected. When I add a legend I cannot seem to be able to set the font family. Can anyone help please. Thanks. Set the family plotting parameter before calling legend() to the value you want. Do this via an explicit call to par() . Here is a simple example x <- y <- 1:10 plot(x, y, type = "n") text(x = 5, y = 5, labels = "foo", family = "serif"

I wish to insert a legend that is not related to the graph whatsoever: figure; hold on; plot(0,0,'or'); plot(0,0,'ob'); plot(0,0,'ok'); leg = legend('red','blue','black'); Now I wish to add it to another figure: figure; t=linspace(0,10,100); plot(t,sin(t)); %% ADD THE LEGEND OF PLOT ABOVE This is how I have solved this problem in the past: figure t=linspace(0,10,100); plot(t,sin(t)); hold on; h = zeros(3, 1); h(1) = plot(NaN,NaN,'or'); h(2) = plot(NaN,NaN,'ob'); h(3) = plot(NaN,NaN,'ok'); legend(h, 'red','blue','black'); This will plot the additional points, but because the coordinates are at

I have almost complete the following graph, but there is one problem with it. The legend in the graph is drawn twice. Here is the data: structure(list(Period = c("January 1997 - August 2003", "September 2003 - Jun 2005", "Jul 2005 - Dec 2009", "January 1997 - August 2003", "September 2003 - Jun 2005", "Jul 2005 - Dec 2009"), Time.Period = structure(c(1L, 3L, 2L, 1L, 3L, 2L), .Label = c("Jan 1997 - Aug 2003", "Jul 2005 - Dec 2009", "Sep 2003 - Jun 2005"), class = "factor"), Variable = structure(c(2L, 2L, 2L, 1L, 1L, 1L), .Label = c("Significant", "Zscore"), class = "factor"), Score = c(8.798129
