donut-chart

Is it possible to create a donut chart with multiple rings using ChartJS as shown below? Varun Mittal You can find out the solution at fiddle link var ctx = document.getElementById("chart-area").getContext("2d"); var myDoughnut = new Chart(ctx, config); var config = { type: 'doughnut', data: { datasets: [{ data: [ 10,20,30 ], backgroundColor: [ "#F7464A", "#46BFBD", "#FDB45C" ], }, { data: [ randomScalingFactor(), randomScalingFactor(), randomScalingFactor() ], backgroundColor: [ "#F7464A", "#46BFBD", "#FDB45C" ], }], labels: [ "Red", "Green", "Yellow" ] }, options: { responsive: true } };

I am using aChartEngine Library to make donut graph.But having problem to add image inside of donut Graph. I can set Background Color only , but not get able to set background image inside of donut. Please check image . This could help.. <RelativeLayout android:layout_width="match_parent" android:layout_height="170dp" > <LinearLayout android:id="@+id/left_graph_for_head_injury" //here to draw donut android:layout_width="match_parent" android:layout_height="170dp" > </LinearLayout> <ImageView //image to place android:layout_width="95dp" android:layout_height="95dp" android:layout_centerInParent

I'm drawing charts with d3.js. Is it possible to add radial gradients to donut chart, how on this picture? Erik Dahlström Assuming the arc parts are path elements that are filled you can use a radial gradient to get that result. See this similar question , we can reuse the example to arrive at: var dataset = { apples: [53245, 28479, 19697, 24037, 40245], }; var width = 460, height = 300, radius = Math.min(width, height) / 2; var color = d3.scale.category20(); var pie = d3.layout.pie() .sort(null); var arc = d3.svg.arc() .innerRadius(radius - 100) .outerRadius(radius - 50); var svg = d3.select(

I've been searching for the solution to generate the simplest donut chart with Highcharts library. However, all examples of Highcharts show the style of chart with both inner pie and outer donut (refer to: http://www.highcharts.com/demo/pie-donut ) How can I get rid of the inner pie and just keep the outer donut, just like other libraries do? (something like RGraph: http://www.rgraph.net/examples/donut.html ) Thank you. You just need to provide the data as an array of two element (key / value) arrays. Specify an innerSize to get the donut style. So your parameters will contain something like

I'm trying to create circular heatmap with ggplot2 so I can use a larger number of labels around the circumference of a circle. I'd like to have it look more like a donut with an empty hole in the middle but at the same time not losing any rows (they would need to be compressed). Code for what I have is below. library(reshape) library(ggplot2) nba <- read.csv("http://datasets.flowingdata.com/ppg2008.csv") nba$Name <- with(nba, reorder(Name, PTS)) nba.m <- melt(nba) nba.m <- ddply(nba.m, .(variable), transform, value = scale(value)) p = ggplot(nba.m, aes(Name,variable)) + geom_tile(aes(fill =
