legend

How do I change the geom_text legend key symbol? In the example below, I'd like to change the symbol in the legend key from a lower case "a" to, say, an upper case "N". I've looked at an example for doing something similar here , but couldn't get that example to work. # Some toy data df <- expand.grid(x = factor(seq(1:5)), y = factor(seq(1:5)), KEEP.OUT.ATTRS = FALSE) df$Count = seq(1:25) # An example plot library(ggplot2) ggplot(data = df, aes( x = x, y = y, label = Count, size = Count)) + geom_text() + scale_size(range = c(2, 10)) EDIT: updating for ggplot version 0.9.2 The original answer

I have an R Shiny app that uses Leaflet to create an interactive map. On this map, a categorical variable is used to designate different kinds of points and is visualized using custom markers (different icons, depending on the factor level). What I would like to do is add a legend to the plot, but have the legend show the various marker icons instead of solid colours. The legends tutorial does not cover this. I have come across another SO answer that seems to solve this - but it was done in JavaScript and I'm not sure how to translate it/if it can be translated to work in R. Anyone know how to

I have a matplotlib plot generated with the following code: import matplotlib.pyplot as pyplot Fig, ax = pyplot.subplots() for i, (mark, color) in enumerate(zip( ['s', 'o', 'D', 'v'], ['r', 'g', 'b', 'purple'])): ax.plot(i+1, i+1, color=color, marker=mark, markerfacecolor='None', markeredgecolor=color, label=i) ax.set_xlim(0,5) ax.set_ylim(0,5) ax.legend() with this as the generated figure: I don't like the lines through the markers in the legend. How can I get rid of them? You can specify linestyle="None" as a keyword argument in the plot command: import matplotlib.pyplot as pyplot Fig, ax =

I have the following dataset: x = [0, 1, 2, 3, 4] y = [ [0, 1, 2, 3, 4], [5, 6, 7, 8, 9], [9, 8, 7, 6, 5] ] Now I plot it with: import matplotlib.pyplot as plt plt.plot(x, y) However, I want to label the 3 y-datasets with this command, which raises an error when .legend() is called: lineObjects = plt.plot(x, y, label=['foo', 'bar', 'baz']) plt.legend() File "./plot_nmos.py", line 33, in <module> plt.legend() ... AttributeError: 'list' object has no attribute 'startswith' When I inspect the lineObjects : >>> lineObjects[0].get_label() ['foo', 'bar', 'baz'] >>> lineObjects[1].get_label() ['foo',

I have a plot where different colors are used for different parameters, and where different line styles are used for different algorithms. The goal is to compare the results of the different algorithms performed with similar parameters. It means in total I use 4 different colors, and 3 different line styles, for a total of 12 plots on the same graph. I actually build the legend based on colors, associating each color with the corresponding parameter. Now I'd like to display a second legend on the same graph, with the meaning of each line style. It is possible to achieve that? How? Here is what
