radar-chart

问题 I'd like to draw a radar chart using MS Chart control in a WinForms app. This chart contains data for 1 day, I have data for every seconds, so I have 86 400 x-y value pairs. X axis contains dates, y my int values. My test code is like this: var fromDate = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 0, 0, 0); var toDate = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 23, 59, 59); List<DateTime> xValues = new List<DateTime>(); List<double>

问题 I am trying to align labels of my radar plot with axis and I face difficulties. Without label alignment, my labels are centered and exceed the axis line . When I set for the first half of my labels (the right side of the figure) alignment to left and for the second half the alignment to the right I get a non "circular" alignment To do so I looped within xticklabels and set horizontal alignment. # Draw one axe per variable + add labels labels yet plt.xticks(angles, categories) for label,i in

问题 I've been working on a radar plot recently and found a great bit of code on from Erwan Le Pennec. I've made a few edits, however there are some parts I couldn't work out how to remove the outermost circle as it doesn't define a value. Currently the code is plotting the major grid lines. I've tried to trick it into removing both axis and only plotting the minor increments however either has worked. Cheers! Here is my code: coord_radar <- function (theta = "x", start = 0, direction = 1) { theta

问题 This is following my previous post: How to measure the area of a polygon in ggplot2? What I would like now to do is to use the resulting radar charts as data points in a totally separate scatterplot or maybe save the object and use it later on graphs to depict the shape of the actual data. I have many files and they typically look like this. They range from 1 to many in col number and the fractions are always in descending format. ie #1 always contributes most in any given file. myfile 01 0

问题 I have some problems with RadarChart labels. Specifically, if I use long texts (e.g. 15-20 chars), and the available space is not too big, the chart gets collapsed and the labels are positioned inside the collapsed chart (but there is clearly more space available). I tried to use ValueFormatter for the label axis that truncates labels if they are longer than 5 chars, but as I see, the chart size calculaction is based on the full label text, as the chart got collapsed the same way I described

问题 Consider a sequence of data along the following lines: data = [{angle:1.2,value:1.2},...,{angle:355.2: value:5.6}]; I'd like to display this data on a radially scaled plot (i.e. circular bands indicating how high the value of each point is) to show angle vs value. Angles will change by a small but uncontrollable quantity for each data set but there will always be ~50 of them spaced fairly evenly around the chart. It looks like chart.js has two options which don't quite fit the bill: A Radar

问题 I use Chart.js to display a Radar Chart. My problem is that some labels are very long : the chart can't be display or it appears very small. So, is there a way to break lines or to assign a max-width to the labels? Thank you for your help! 回答1: For Chart.js 2.0+ you can use an array as label: Quoting the DOCs: "Usage: If a label is an array as opposed to a string i.e. [["June","2015"], "July"] then each element is treated as a seperate line." var data = { labels: [["My", "long", "long", "long

问题 As part of a loop I am creating several radarcharts. Each chart is a country, the information displayed in the cobweb are data for several years (lines of different colors). I am trying to add a legend which would make it clear which line (color) relates to which year. As far as I could see, the help file on radarchart is silent on this. (I saw the previous post on this matter, but don't think it's applicable since I am here working in a loop). I would be grateful for any hint. Here is the

问题 I asked in a previous question how to set a specific number of rings and sectors for a polar diagram . I now have a button which changes the chart from polar to radar. The problem is the number of segments changes from 24 (correct) to 25 (wrong). I have no idea why. The code to set the number of rings: #region chartdesign Series s = chartleft.Series[0]; // a reference to the default series ChartArea ca = chartleft.ChartAreas[0]; // a reference to the default chart area Axis ax = ca.AxisX;

问题 How would you move the labels along each axis so they're all readable? For example, how would you move the '$156, $158, $160' out of the way of the axis? This post shows how you can move these labels if you only have one axis, but what would you do if you had multiple as in my situation? Move radial tick labels on a polar plot in matplotlib import numpy as np import pylab as pl import matplotlib.pyplot as py class Radar(object): def __init__(self, fig, titles, labels, rect=None): if rect is
