legend

问题 There are 2 lists called listversion & MIN_list . Using values of these list I have created a line chart. Everything is work fine. But I am wondering whether it is possible to add a data table with legend keys in to the chart like MS Excel. chart.Series.Clear(); chart.ChartAreas[0].AxisX.Title = "Version"; chart.ChartAreas[0].AxisX.TitleFont = new System.Drawing.Font("Arial", 12, FontStyle.Regular); chart.ChartAreas[0].AxisY.Title = "Time"; chart.ChartAreas[0].AxisY.TitleFont = new System

问题 I am producing some plots in matplotlib and would like to add explanatory text for some of the data. I want to have a string inside my legend as a separate legend item above the '0-10' item. Does anyone know if there is a possible way to do this? This is the code for my legend: ax.legend(['0-10','10-100','100-500','500+'],loc='best') 回答1: Sure. ax.legend() has a two argument form that accepts a list of objects (handles) and a list of strings (labels). Use a dummy object (aka a "proxy artist")

问题 I have a simple data frame that I'm trying to do a combined line and point plot using ggplot2 . Supposing my data looks like this: df <- data.frame(x=rep(1:10,2), y=c(1:10,11:20), group=c(rep("a",10),rep("b",10))) And I'm trying to make a plot: g <- ggplot(df, aes(x=x, y=y, group=group)) g <- g + geom_line(aes(colour=group)) g <- g + geom_point(aes(colour=group, alpha = .8)) g The result looks fine with one exception. It has an extra legend showing the alpha for my geom_point layer. How can I

问题 I have a PieChart with many sections, legend for this PieChart renders as one row. How to render legend as two columns? 回答1: The method getLegendItem() , seen here, provides all the information needed to render a legend item in any Container you choose. GridLayout(0, 2) will arrange them in two columns for any number of rows. To suppress the existing legend, set legend to false when you call your chart factory; the items will still be available, as suggested here. Addendum: Based on

问题 I created a 4D scatter plot graph to represent different temperatures in a specific area. When I create the legend, the legend shows the correct symbol and color but adds a line through it. The code I'm using is: colors=['b', 'c', 'y', 'm', 'r'] lo = plt.Line2D(range(10), range(10), marker='x', color=colors[0]) ll = plt.Line2D(range(10), range(10), marker='o', color=colors[0]) l = plt.Line2D(range(10), range(10), marker='o',color=colors[1]) a = plt.Line2D(range(10), range(10), marker='o'

问题 As the title says: How can I plot a legend outside the plotting area when using base graphics? I thought about fiddling around with layout and produce an empty plot to only contain the legend, but I would be interested in a way using just the base graph facilities and e.g., par(mar = ) to get some space on the right of the plot for the legend. Here an example: plot(1:3, rnorm(3), pch = 1, lty = 1, type = "o", ylim=c(-2,2)) lines(1:3, rnorm(3), pch = 2, lty = 2, type="o") legend(1,-1,c("group

问题 I am trying to plot a line plot in r by using ggplot. Unfortunately, the legend does not show up. Can anyone help me? My code looks like the following: dfdatavgsM=data.frame(datum, avgsätzegespMT, avgsätzegespML) ggplot(data = dfdatavgsM, aes(x=datum, color=Wettbewerbsart)) + geom_line(data=dfdatavgsM, aes(y = avgsätzegespML),color="red") + geom_line(data=dfdatavgsM, aes(y = avgsätzegespMT), color="blue") + geom_vline(xintercept=2011, size = 0.6) + scale_y_continuous(name="Anzahl an Sätzen")

问题 I tried to generate a legend for my ggplot, where I want to illustrate five different lines over a time horizon of 2,5 months with 11 datapoints. I can generate the graph, but it doesn't work to get the legend comparing to the colors and names of the lines. I tried different commands, i.e. scale_colour_manual, scale_fill_discrete, opts, guides,... but nothing works. I don't know what's wrong.. Can please anybody help me? Here are the commands to the define the data frame. Spaß <- read.csv

问题 I am plotting with ggmap and ggplot2 using geom_point . I want to add annotation text (i.e., 1 to 19) close to the points as well. Here is my code: setwd("../Documents/MAPS") library(ggplot2) library(mapproj) library(maps) library(maptools) library(rgdal) library(ggmap) library(sp) bdl_sites <- get_map(location =c(lon = 34.832, lat = 0.852), colour = "colour", source = "google", maptype = "terrain", zoom = 9) save(bdl_sites, file = "bdl_sites.rda") load(file = "bdl_sites.rda") BDL_Org_Data
