legend

I have data that results in multiple lines being plotted, I want to give these lines a single label in my legend. I think this can be better demonstrated using the example below, a = np.array([[ 3.57, 1.76, 7.42, 6.52], [ 1.57, 1.2 , 3.02, 6.88], [ 2.23, 4.86, 5.12, 2.81], [ 4.48, 1.38, 2.14, 0.86], [ 6.68, 1.72, 8.56, 3.23]]) plt.plot(a[:,::2].T, a[:, 1::2].T, 'r', label='data_a') plt.legend(loc='best') As you can see at Out[23] the plot resulted in 5 distinct lines. The resulting plot looks like this Is there any way that I can tell the plot method to avoid multiple labels? I don't want to

I would like to put my plot legend inside the plot, inside the first plot of a facet. Here is some example code: df=data.frame( x=runif(10), y=runif(10), facet=rep(c("a","b"),5), color=rep(c("red","blue"),5)) ggplot(data=df,aes(x=x,y=y,color=color))+ geom_point()+ facet_wrap(~facet,ncol=1) Here is the resulting plot: And here is roughly how I would like it to look: Thanks for any help you can provide! Richie Cotton Assuming your plot is saved as p p + opts( legend.position = c(0.9, 0.6), # c(0,0) bottom left, c(1,1) top-right. legend.background = theme_rect(fill = "white", colour = NA) ) If

On certain LCD monitors, the color of the horizontal lines in the legend is hard to tell apart. (See the image attached). So instead of drawing a line in the legend, is it possible to just color code the text itself? so another words, have "y=0x" in blue, "y=1x" in green, etc... import matplotlib.pyplot as plt import numpy as np x = np.arange(10) fig = plt.figure() ax = plt.subplot(111) for i in xrange(5): ax.plot(x, i * x, label='$y = %ix$' % i) ax.legend() plt.show() PS. if the line could be made thicker just in the legend, but not in the plot, this would also work. Just set the linewidth of

I’d like to include a legend or key in my GraphViz diagram. I’m having trouble figuring out what code to use, though. I also want to put it in a corner, but the only coord I know for sure is the bottom-left: pos="10,10!" . Does anyone know how I can get this to work? digraph { rankdir=LR node [shape=plaintext] subgraph cluster_01 { label = "Legend"; key [label=<<table border="0" cellpadding="2" cellspacing="0" cellborder="0"> <tr><td align="right" port="i1">item 1</td></tr> <tr><td align="right" port="i2">item 2</td></tr> <tr><td align="right" port="i3">item 3</td></tr> <tr><td align="right"

For some reason, I would like to plot the line and marker of the same data separately. data1 = (1:1:10)'; data2 = (1:2:10); figure(1); plot(data1,data1,'or'); hold on; plot(data2,data2,'-r'); legend('data'); However it will only display the legend for the first plot. And Matlab seems not to have option to manipulate the legend marker, color and linestyle. How can I make legend like this? Thanks! You will need to plot an invisible third plot (with almost no data to keep it fast) to define your legend: data1 = (1:1:10)'; data2 = (1:2:10); figure(1); plot(data1,data1,'or'); hold on plot(data2
