legend

问题 I am plotting a choropleth map in python from a shapefile and i want to customize the legend of the plot, i am using the code bellow: import pandas as pd import pysal as ps import geopandas as gp import numpy as np import matplotlib.pyplot as plt pth = 'outcom.shp' tracts = gp.GeoDataFrame.from_file(pth) ax = plot_dataframe(tracts, column='Density', scheme='QUANTILES', k=4, colormap=plt.cm.Blues, legend=True) plt.show() Besides, i am using a small patch that i found here http://nbviewer

问题 I'm pretty new to D3.js (I'm a R programmer). I'm trying to create a scatter and put a legend in the right bottom. However, it's overlapping with chart area. I've been trying to take some examples in internet with no lucky. When I try to move it to the right, the names and/or symbols are not visible. I want to place the legend outside the chart frame, so it won't overlap. Any help is appreciated. Here's what I tried so far: d3.csv('https://gist.githubusercontent.com/netj/8836201/raw

问题 I'm producing a plot_gene_map figure by the genoPlotR R package, which gives a horizontal phylogenetic tree where aligned with each leaf is a genomic segment. Here's a simple example that illustrates my usage and problem: The plot_gene_map function requires an ade4 s' package phylog object which represents the phylogenetic tree: tree <- ade4::newick2phylog("(((A:0.08,B:0.075):0.028,(C:0.06,D:0.06):0.05):0.0055,E:0.1);") A list of genoPlotR 's dna_seg objects (which are essentially data.frame

问题 I am currently finishing a bigger project and the last part is to add a simple legend to a plot of a multicolored line. The line only contains two different colors. The following image shows the plot when created. The next image shows the same plot with higher resolution. The plot displays the distance between Earth and Mars over time. For the months March to August the line is orange, for the other months it's blue. The legend should come in a simple box in the upper right corner of the plot

问题 This question already has answers here : How to create pre-annotated rowside column in heatmap.2 (2 answers) Closed 2 years ago . I have the following MWE in which I make a heatmap without performing any clustering and showing any dendrogram. I want to group my rows (genes) together in categories, in a better looking way than how it is now. This is the MWE: #MWE library(gplots) mymat <- matrix(rexp(600, rate=.1), ncol=12) colnames(mymat) <- c(rep("treatment_1", 3), rep("treatment_2", 3), rep(

问题 Here is the sample code: x = rand(100,1); y = rand(100,1); score = rand(100,1); figure; colormap(flipud(bone)); caxis([0 1]) axis([0 1 0 1]) scatter(x,y,50,score,'+','LineWidth',2); legend('scores'); I'm using the reversed 'bone' colormap which assigns pure white to score value 0 and pure black to score value 1. However, the legend seems to be automatically assigned the score 0, and so if you run the code the legend color is pure white and not visible. Is there any ways to fix that? Thanks.

问题 How does one make a legend for patch patterns used on a graph or add information on the patch patterns to a preexisting legend without affecting information already present on the legend? 回答1: When you create the patch include the kwarg label , ex ## bunch of code ax.add_patch(mpl.patches.Rectangle(...,label='fail')) ## bunch of code ax.plot(...,label='some line') ## bunch of code ax.legend() and it will be automaigically added to your legend. And entry will be added for each artist that you

问题 How can I create one common legend for 4 subplots in MATLAB, like this: 回答1: Quick and dirty: hSub = subplot(3,1,1); plot(1,1,1,1,1,1,1,1); hLegend = legend('hello','i','am','legend'); subplot(3,2,3), plot(10:-1:1); subplot(3,2,4), plot(1:100); subplot(3,2,5), stem(1:10); subplot(3,2,6), plot(randn(1,100)) set(hLegend, 'position', get(hSub, 'position')); 来源： https://stackoverflow.com/questions/26704815/how-to-create-one-common-legend-for-4-subplots-in-matlab

问题 I'm trying to add a legend on a pie when exporting the chart as PNG.

问题 My script for plotting creates two legends for each label. I do not know how to make legend() not duplicate. I checked on stackoverflow and found two methods. But I could not implement them here. Any ideas?
