bubble-chart

I´ve created a bubble chart and I put in some testing values as follow: this.chart1.Series["blueBubble"].Points.AddXY(2, 3, 6); this.chart1.Series["redBubble"].Points.AddXY(1, 0, 7); this.chart1.Series["yellowBubble"].Points.AddXY(1, 3, 8); As I put in the size of the particular bubble to the third parameter of AddXY function, the sizing is done in a completely wrong proportional representation. See picture: How can I change the bubble sizes to the right proposition representation? This looks really weird. The best explanation I have is that the sizes always start with the smallest one set and

I saw a plot generated in excel and I was wondering if R could also do it. This picture is essentially a visualization of a crosstab table comparing the days of the week to preferred meals on that day and counting the number of people that fall within those categories. I've read up on some R bubble charts but I have yet to see one like this. Can someone point me to a package or a website that explains how I can make a plot like this one? Using Hadley Wickham's ggplot2 : library(ggplot2) # Set up the vectors days <- c("Mon","Tues","Wed","Thurs","Fri") slots <- c("Coffee/Breakfast","Lunch",

I have a Highcharts bubble chart where many of the points are going to have the same, or very similar values. Currently only the top point's data label is visible. I have functionality that allows the points to be highlighted (using the select() method). When a point is selected I am also moving it to the top by using point.graphic.toFront() , but I also want the selected point's data label to be moved to the top too. I can't figure out how to do that or if it's possible. Is there a way to move an individual point's data label to the front/top so that it can be seen? I know there is a setting

I'm using nvd3 and have a few charts where the legend is much to large. E.g. a scatter/bubble with 15 groups and the group names are long. The legend is so large that it leaves almost no room for the chart itself. Is there a way to remove the legend or toggle the legend or limit the height/width it is taking up? Any example would be great. Also, is there a way to have the bubble show a descriptive string? Right now when you stand on top of a bubble it highlights the x/y coordinates. I also want it to show the bubble name. For example, each of my bubbles represents a country (which has a name),

I am learning d3. There are certain ways of loading the data in d3 js. But all of them seem to make a HTTP GET. In my scenario, I already have the json data in a string. How can I use this string instead of making another http request? I tried to look for documentation for this but found none. This works: d3.json("/path/flare.json", function(json) { //rendering logic here } Now, if I have: //assume this json comes from a server (on SAME DOMAIN) var myjson = '{"name": "flare","children": [{"name": "analytics","children": [{"name": "cluster","children": [{"name": "MergeEdge", "size": 10 }]}]}]}'
