Relationship Graph with D3

阅读更多关于 Relationship Graph with D3

问题 How would I create the following graph with D3? I don't know the name for this type of visualization, and the closest I could find were "force-directed" graphs. Legend: Filled nodes are people, non-filled nodes are attributes (e.g. favorite color). 回答1: This is my version: http://jsfiddle.net/doraeimo/JEcdS/embedded/result/ which is easy to show system performance and network flow. code is not here 回答2: Hacked together a gross but working version: http://bl.ocks.org/hijonathan/5793014

Adding one label to each bar graph r

阅读更多关于 Adding one label to each bar graph r

问题 I am trying to compile a graphical depiction of test scores from 50 students. My ultimate goal would be to create 50 variations of the bar chart, one for each student, with only the one student's name on the axis so he/she can see how they compare to the others without disclosing who scored what. In the photo below, I would like to put "Jackson" on the first bar and leave the others blank for the first variation. The second would only have "Smith", etc. Additionally, I would like to split the

How to read in data into d3.js from multiple javascript arrays? And dynamically updating chart without refreshing the page

阅读更多关于 How to read in data into d3.js from multiple javascript arrays? And dynamically updating chart without refreshing the page

问题 Currently I have two arrays, one is a list of numbers titled nums, and the ms is a list of strings titled places. Ex. nums=[1,2,3,4,5] places = ["house","gym", "work", "school", "park"] both arrays are the same length. I want to make a bar chart with these arrays that looks similar to http://bl.ocks.org/mbostock/3885304, but the data is coming from these arrays rather than a tsv file. In Bostock's code the data is read in from a tsv file, the code is below. d3.tsv("data.tsv", type, function

Add or highlight a single points on a jQuery flot graph?

阅读更多关于 Add or highlight a single points on a jQuery flot graph?

I've already drawn a flot graph using some data: var plot = $.plot($("#placeholder"), [{ data: data, }], { series: { points: { show: true } }, grid: { hoverable: true, } }); Now I'd like to highlight a single point on the graph, when a user hovers over an item elsewhere on the page. I found this question , which explains how to totally redraw the series from scratch, but is there a way to highlight a single point? Or add a new point in a different colour, which would have the effect of a highlight? NB: when the user hovers over the relevant item elsewhere on the page, I will have the x and y

making a function that translates a point around another point

阅读更多关于 making a function that translates a point around another point

问题 given an array of points my program should in theory, Find the two furthest points from each other. Then calculate the angle that those two points make with the x axis. Then in rotate all the points in the array around the averaged center of all the points by that angle. For some reason my translation function to rotate all the points around the center is not working it is giving me unexpected values. I am fairly sure the math I am using to do this is accurate since I tested the formula I am

问题 Can someone please provide a simple example of adding a line series to an UltraChart from a data table? The table has time series values (time values on x-axis, measurement (double) values on the y-axis). So far the only examples I've seen where time series are added to the Chart are for a finite set of hard-coded datapoints. I want to be able to fee the data series from a selection in the table. Any thoughts ideas and/or advice is greatly appreciated. Thanks, Ruben. 回答1: Define a Numeric

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . there is a very good java graphing library JUNG I wonder if there exists any GWT library that does what JUNG do ? i'm aware there exist a commercial Javascript graphing library mxGraph. But mxGraph is very expensive and have a very restrictive licensing policy. does anyone knows of any GWT graphing library

Can someone explain how to graph this sum in MATLAB using contourf?

阅读更多关于 Can someone explain how to graph this sum in MATLAB using contourf?

问题 I'm going to start off by stating that, yes, this is homework (my first homework question on stackoverflow!). But I don't want you to solve it for me, I just want some guidance! The equation in question is this: I'm told to take N = 50, phi1 = 300, phi2 = 400, 0<=x<=1, and 0<=y<=1, and to let x and y be vectors of 100 equally spaced points, including the end points. So the first thing I did was set those variables, and used x = linspace(0,1) and y = linspace(0,1) to make the correct vectors.

问题 Is there a way to continously plot changing array data? I've got a ILLinePlot to graph the line to changing data on a button event, but I would like to make it continuous. while (true) { float[] RefArray = A.GetArrayForWrite(); //RefArray[0] = 100; Shuffle<float>(ref RefArray); Console.Write(A.ToString()); scene = new ILScene(); pc = scene.Add(new ILPlotCube()); linePlot = pc.Add(new ILLinePlot(A.T, lineColor: Color.Green)); ilPanel1.Scene = scene; ilPanel1.Invalidate(); } The problem I'm
