legend

问题 I made a plot with 2 Y axes, where one has a bar chart and the other one lines and I would like to add a common legend for both plots. If I add the following: axis1.legend([(bar1, line1), (bar2, line2)], ['Solution 1', 'Solution 2'], loc='upper left', numpoints=1) I almost get what I want, except for the markers / artists (not sure which term is suitable here), which are overlapping for both solutions as seen here: Is it possible to have the bar artist first and the line artist second, side

问题 I'm trying to get labels left-aligned and values right-aligned in the legend. In below code, I've tried with format method, but the values are not properly aligned. Any hint/suggestions is greatly appreciated. import matplotlib.pyplot as pl # make a square figure and axes pl.figure(1, figsize=(6,6)) labels = 'FrogsWithTail', 'FrogsWithoutTail', 'DogsWithTail', 'DogsWithoutTail' fracs = [12113,8937,45190, 10] explode=(0, 0.05, 0, 0) pl.pie(fracs, explode=explode, labels=labels, autopct='%1.1f%

问题 I try to add the legend which should, according to my example, output: a red square with the word fruit and a green square with the word veggie. I tried several things (the example below is just 1 of the many trials), but I can't get it work. Can someone tell me how to solve this problem? import pandas as pd from matplotlib import pyplot as plt data = [['apple', 'fruit', 10], ['nanaba', 'fruit', 15], ['salat','veggie', 144]] data = pd.DataFrame(data, columns = ['Object', 'Type', 'Value'])

问题 I'm trying to get two words aligned in a legend in matplotlib. With the print statement I can do this using the tools available to format (< for left alignment, > for right alignment), but in the legend this has a different result. import matplotlib.pyplot as plt import numpy as np str1 = r'{:<18} {:>12}'.format('HadGEM2-ES'+',', r'$\lambda$') str2 = r'{:<18} {:>12}'.format('inmcm4'+',', r'$\lambda$') print(str1) print(str2) plt.plot(np.arange(10), label=str1) plt.plot(0.8*np.arange(10),

问题 This question already has answers here : Add legend to ggplot2 line plot (3 answers) Closed 22 days ago . I'm new to ggplot and I'm trying to figure out how to add a legend to a graph and re-label the x-axis. I've enclosed the plotting code and resulting graph . I would like to add a legend that explains what the blue line and the green and red dots are. I would also like the years on the x-axis to appear as 2018, 2019, ... , 2020 instead of 2017.5, 2010.0, ..., 2020.0. I can't find a

问题 I need to assemble a Matlab/Octave legend for indexed curves, and I found the following example which seems to work well: legend(strcat("curve ", num2str(1:2))) Associates the labels "curve 1" and "curve 2" with the two curves given. However, if I need to add a different, non-indexed type of curve, the method above seems not to work anymore. legend(strcat("curve ", num2str(1:2)),"another curve") In the second example the first curve has for legend ["curve 1"; "curve 2"], and the second curve

问题 I have a stacked vbar chart in Bokeh, a simplified version of which can be reproduced with: from bokeh.plotting import figure from bokeh.io import show months = ['JAN', 'FEB', 'MAR'] categories = ["cat1", "cat2", "cat3"] data = {"month" : months, "cat1" : [1, 4, 12], "cat2" : [2, 5, 3], "cat3" : [5, 6, 1]} colors = ["#c9d9d3", "#718dbf", "#e84d60"] p = figure(x_range=months, plot_height=250, title="Categories by month", toolbar_location=None) p.vbar_stack(categories, x='month', width=0.9,

问题 So I know many people have asked similar questions but the code others have used does not seem to be working for my graph hence why I'm wondering if I have done something wrong. I have this code: ggplot(dfMonth) + geom_col(aes(x=Month, y=NumberMO), size=.7, colour="black", fill="white") + geom_line(aes(x=Month, y=NumberME), size=1, colour="black", group=1) + xlab("Month") + ylab("No. of birds observed") + theme_bw() + geom_point(x=Month, y=NumberME) + scale_colour_manual("" ,values =c(

问题 I cannot figure out how to make two separate legends for my geom_point and my geom_line data. Currently, I have a legend describing what the different linetypes mean, but when I try to add a legend to describe what the different point shapes mean (blue triangles and circles), blue circles simply overlap the linetype legend. Many thanks to anyone who can help me make two separate legends for linetype and point shape. Below is my code, my data, and a picture of my current graph: Here's my data,
