bubble-chart

I want to create a single legend for a bubble chart with positive and negative values like in plot below , generated using sp::bubble(). But, for various reasons I want to duplicate this in ggplot2. The closest I have gotten is to generate a single legend with scaled symbols, but the actual bubbles themselves are'nt scaled. The above plot was created using the code below # create data frame x=sample(seq(1,50),50,T) y=sample(seq(1,50),50,T) plot_dat=data.frame(x=x,y=y,value=rnorm(50,0,25)) # plot library(ggplot2) ggplot(data=plot_dat, aes(x=x, y=y,colour=factor(sign(value)), size=value)) + geom

I'm building a Highcharts bubble chart and am running into a challenge formatting the data labels. The data will be regularly updated, so there will be plenty of times when the bubbles either overlap or are very close to each other. By default, labels that are very close to one another will be omitted. However, my requirements for this chart include showing the data labels for all bubbles, regardless of their position (therefore, I'm setting allowOverlap to true ). Here is a variation of the demo bubble chart that shows my issue (see also the screenshot below): http://jsfiddle.net/brightmatrix

I'm trying to produce a nice bubble plot overlaid on top of a basemap of the US (i could import a shapefile if that is preferred but i've been using the R basemaps. library(ggplot2,sp,raster,maps,mapdata,maptools,ggmap,rgeos) myData = data.frame(name=c("Florida","Colorado","california","Harvard","Yellowstone"), lat=c(28.1,39,37,42,44.6), long=c(-81.6,-105.5,-120,-71,-110), pop=c(280,156,128,118,202)) Using this code below, that i adapted from another stack overflow post ( Create bubble plot in R using satellite map ), i am able to overlay a bubble plot on a map of the US. However this renders

I have been trying to build a Choropleth / Bubble map of UK for my own shiny dashboard project. My dashboard is a student information management system and the map is supposed to show students come from which regions (zip codes or cities is also fine). Unfortunately, most packages, such as plotly and ggmap, only cover information about states of USA. So, could someone please tell me how to create a map for UK? Here is an example of what I am trying to accomplish: Choropleth Map for UK This is a step-by-step implementation of what I meant by my comment. I did not use the External Post that I

I want to insert some text inside my Circle which is plot in bubble chart using D3.js. I am able to draw circle in svg as per the data provided to it, but facing a problem while append text to it. below is my code: <script type="text/javascript"> var sampleData = [{"x": 8,"y": 1}, {"x": 2,"y": 1}, {"x": 4,"y": 1},{"x": 5,"y": 1}]; // {"x": 6,"y": 40}, {"x": 8,"y": 100}, {"x": 10,"y": 60}]; $(function() { InitChart(); }); function InitChart() { // Chart creation code goes here var vis = d3.select("#svgVisualize"); var xRange = d3.scale.linear().range([40, 400]).domain([0,10]); var yRange = d3
