legend

问题 EDIT : As of 2012-06-11 this bug has been finally fixed! https://bugs.webkit.org/show_bug.cgi?id=35981#c1 I have some pretty straightforward markup: <form action=""> <fieldset class="compact"> <legend>Member Tools</legend> <label for="username">Username</label> <input name="username" id="username" type="text"/> <label for="password">Password</label> <input name="password" id="password" type="password" /> </fieldset> </form> I am attempting to add a small margin to the bottom of the legend

问题 I'm making a scatter plot which looks like this: (MWE at bottom of question) As can be seen in the image above the colors of the points in the legend are set to blue automatically by matplotlib . I need to set this points to some other color not present in the colormap (ie: black) so they won't generate confusion with the colors associated with said colormap. I looked around but the matplotlib.legend module does not seem to accept a color keyword. Is there any way to do this? Here's the MWE:

问题 I'm trying to plot some overlapping density plots in ggplot2. I'm running into a problem where I cannot remove the diagonal slash from the legend. I have tried using scale_fill_manual() and legend.key as well as the hack from R Cookbook, but I cant seem to get it right. data(iris) iris=iris cols=brewer.pal(3,"Set1") ggplot(iris) + geom_density(position="identity",aes(x=iris$Sepal.Length,fill=cols[1]), colour="black",alpha=.5) + geom_density(position="identity",aes(x=iris$Sepal.Width,fill=cols

问题 I created a column chart in my application which look like this: As you can see the positive values are green and the negative values are red. I need to represent this in the legend. I just don't know how. What I already tried: I added CustomItems to the Legend . Here is the code: Legend currentLegend = chart.Legends.FindByName(chart.Series[series].Legend); if (currentLegend != null) { currentLegend.LegendStyle = LegendStyle.Table; LegendItem li = new LegendItem(); li.Name = series; li.Color

问题 I would like to use image instead of labels in the legend. For example, I draw 2 lines and show a legend : import matplotlib.pyplot as plt plt.plot([1,2],label="first_image") plt.plot([2,1],label="second_image") plt.legend() plot.show() But I would like to have something like this : Note that this is not a duplicate of Insert image in matplotlib legend , My issue is "change the label into an image", while the other is "change the legend's symbol into an image" 回答1: The concept for creating an

问题 I'm making some scatter plots and I want to set the size of the points in the legend to a fixed, equal value. Right now I have this: import matplotlib.pyplot as plt import numpy as np def rand_data(): return np.random.uniform(low=0., high=1., size=(100,)) # Generate data. x1, y1 = [rand_data() for i in range(2)] x2, y2 = [rand_data() for i in range(2)] plt.figure() plt.scatter(x1, y1, marker='o', label='first', s=20., c='b') plt.scatter(x2, y2, marker='o', label='second', s=35., c='r') # Plot

问题 An example using ggplot2 to graph groups of data points and lines connecting the means for each group, mapped with the same aes for shape and for linetype : p <- ggplot(mtcars, aes(gear, mpg, shape = factor(cyl), linetype = factor(cyl))) + geom_point(size = 2) + stat_summary(fun.y = mean, geom = "line", size = 1) + scale_shape_manual(values = c(1, 4, 19)) Problem is that point symbols in the legend appear a bit too small to see, relative to the line symbols: Trying to enlarge point size in

问题 I plot a 2 geom_point graph with the following code: source("http://www.openintro.org/stat/data/arbuthnot.R") library(ggplot2) ggplot() + geom_point(aes(x = year,y = boys),data=arbuthnot,colour = '#3399ff') + geom_point(aes(x = year,y = girls),data=arbuthnot,shape = 17,colour = '#ff00ff') + xlab(label = 'Year') + ylab(label = 'Rate') I simply want to know how to add a legend on the right side. With the same shape and color. Triangle pink should have the legend "woman" and blue circle the

问题 I got a for i=1:15 . Inside I generate a variable d=1:0.01:10 , which is the x'x axis and based on this, I create a continuous function F(d) which has 2 unique variables pitch and yaw. I then plot this using different colors in every recursion using cmap = hsv(15); . So then it is: d=1:0.01:10; cmap = hsv(15); for i=1:15 pitch = unidrnd(10); yaw = unidrnd(10); for j=1:length(d) F(j) = d(j)*3*pitch*yaw; %// some long calculation here end p1 = plot(d,F,'Linewidth', 1.0); title ('blah blah') set

问题 Here is a very simplified example: xvalues = [2,3,4,6] for x in xvalues: plt.axvline(x,color='b',label='xvalues') plt.legend() The legend will now show 'xvalues' as a blue line 4 times in the legend. Is there a more elegant way of fixing this than the following? for i,x in enumerate(xvalues): if not i: plt.axvline(x,color='b',label='xvalues') else: plt.axvline(x,color='b') 回答1: plt.legend takes as parameters A list of axis handles which are Artist objects A list of labels which are strings
