Alternative solution, kind of dirty but pretty quick. import pylab as plt X = range(50) Y = range(50) plt.plot(X, Y, label=”Very straight line”) # Create empty plot with blank marker containing the extra label plt.plot([], [], ‘ ‘, label=”Extra label on the legend”) plt.legend() plt.show()

You can use override.aes= inside guides() function to change default appearance of legend. In this case your guide is color= and then you should set shape=c(NA,16) to remove shape for line and then linetype=c(1,0) to remove line from point. ggplot(df) + geom_line(aes(id, line, colour = “line”)) + geom_point(aes(id, points, colour = “points”))+ guides(color=guide_legend(override.aes=list(shape=c(NA,16),linetype=c(1,0))))
I don’t think there’s a legend handler for text (see the list of available ones here). But you can implement your own custom legend handler. Here I’ll just modify the example at the above link: import matplotlib.pyplot as plt import matplotlib.text as mpl_text class AnyObject(object): def __init__(self, text, color): self.my_text = text self.my_color = color … Read more
In versions > 0.9.3 (when opts was deprecated) theme(legend.position = “bottom”) Older version: Unfortunately it’s a bug in ggplot2 which I really really hope to fix this summer. Update: The bug involving opts(legend.position = “left”) has been fixed using the most current version of ggplot2. In addition, version 0.9.0 saw the introduction of guide_legend and … Read more
If you rename your columns of the original data frame and then melt it into long format withreshape2::melt, it’s much easier to handle in ggplot2. By specifying the color and shape aesthetics in the ggplot command, and specifying the scales for the colors and shapes manually, the legend will appear. source(“http://www.openintro.org/stat/data/arbuthnot.R”) library(ggplot2) library(reshape2) names(arbuthnot) <- … Read more
Yes you can do that: Here are the steps I took: First we disable the original Legend as it can’t be manipulated the way we need to..: chart1.Legends[0].Enabled = false; Now we create a new one and a shortcut reference to it: chart1.Legends.Add(new Legend(“customLegend”)); Legend L = chart1.Legends[1]; Next we do some positioning: L.DockedToChartArea = … Read more
