pie-chart

问题 I am plotting multiple pie plots with ggplot2 and succeeded in having the labels plotted in the right positions, as: df <- data.frame(annotation=rep(c("promoter", "intergenic", "intragene", "5prime", "3prime"), 3), value=c(69.5, 16, 10.7, 2.5, 1.3, 57.2, 18.8, 20.2, 2.1, 1.7, 50.2, 32.2, 15.3, 1.2, 1.1), treatment=rep(c("treated1", "treated2", "untreated"), c(5, 5, 5))) library(ggplot2) ggplot(data = df, aes(x = "", y = value, fill = annotation)) + geom_bar(stat = "identity") + geom_text(aes

问题 I'm creating a pie chart in highcharts. Does anybody know how to set data labels in two lines? I'm finding this problem when the data labels are too long. http://jsfiddle.net/larrytron/fSjnD/ $(function () { $('#container').highcharts({ chart: { plotBackgroundColor: null, plotBorderWidth: null, plotShadow: false }, title: { text: 'Browser market shares at a specific website, 2010' }, tooltip: { pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>' }, plotOptions: { pie: {

问题 HI all i am some data in a pie chart...on hover of slice i get the hover like this [Hr Resources:x=Hr Resources,y=12] i want my tooltip to show like this [ProjectName=Hr,Logged Bugs=12] how do i do this..here is how i am binding my data to the pie chart <script type="text/javascript"> $(function () { $.getJSON('<%= Url.Action("GetData","JqueryCharts") %>', {}, function (data) { var json = data; alert(json); var jsondata = []; for (var i in json) { // var serie = new Array(json[i].Projects,

问题 I want to rotate the image around its center point.The problem i am facing is i need to get the angle to calculate in touch moved event (i dont want to use multi touch).I am current using the below code - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{ NSArray *allTouches = [touches allObjects]; gestureStartPoint = gestureMovedPoint;//i am getting the gestureStartPoint on touch began event gestureMovedPoint = [[allTouches objectAtIndex:0] locationInView:[self superview]];

问题 The following code represent the data that will be shown in a pie chart visualization in javascript. <script type="text/javascript"> var agg = { label: 'Aggressive', pct: [60, 10, 6, 30, 14, 10] }, bal = { label: 'Balanced', pct: [24, 7, 2, 18, 13, 36] }, mod = { label: 'Moderate', pct: [12, 4, 2, 10, 11, 61] }, inc = { label: 'Income', pct: [ 0, 0, 0, 0, 0,100] }, </script> I would like to have the pct values as php variables, and not fixed as in the code above. How do I do this? I would

问题 I've got a pie chart that looks like this when hovering over a piece of pie: Except for wanting the legend to the right instead of on top, I'm fairly content with this, but I want just the percentage value to display "all the time" in the pie pieces - and still have the <name> (<%val>): <data> displayed on hover. In other words, I want the pie to look something like this: How can I break that one piece of data out (the percentage) and draw that onto each piece of pie? Here is the code I'm

问题 I'm building a dc.js-based visualization where one of the charts is a pie chart. See: http://jsfiddle.net/luiseth/t8we6/ The peculiarity of my case is that the labels that this chart will display are usually rather long, so much that usually get clipped by the chart's container (the <div> ). So I thought of having them appear on a legend, but I haven't been able to figure how to have the legend appear to the right of the chart. How can I do that? Playing around with the width has not helped

问题 I'm looking to reduce the display radius of a pie chart built in ggplot2 relative to the rest of the plot (as the defaults keep cutting off my category labels). Here's some dummy data and code that should show you what I'm experiencing: library(ggplot2) library(scales) library(grid) Region <- c("North America", "Central America", "South America", "Carribbean", "Western Africa", "Northern Africa", "Southern Afica", "Eastern Africa") Conti <- c(rep("Americas",4), rep("Africa",4)) Freq <- c

问题 I am struggling with getting the pie chart labels correct. Looked around and thought that I could easily implement what mathematicalCoffee did. So far I have this code: ltr = LETTERS[seq( from = 1, to = 26)] wght = runif(length(ltr)) wght = wght/sum(wght) wght = round(wght, digits = 2) alloc = as.data.frame(cbind(ltr, wght)) alloc$wght = as.numeric(as.character(alloc$wght)) ggpie <- function (dat, by, totals) { ggplot(dat, aes_string(x=factor(1), y=totals, fill=by)) + geom_bar(stat='identity'

问题 Can we display data in pie chart slice and also tolltip like the above image using chart.js? Updated: Here is my code in php page. printf( '<table>' ); echo '<tr><td style="text-align: right;"><canvas id="pie-canvas-' . $canvasId . '" width=256px height=257px ></canvas></td><td style="text-align: left;width:360px;" id="legend" class="chart-legend"></td></tr>'; echo '<script type="text/javascript">drawPie(' . $canvasId . ', ' . $data .', ' . $legend . ');</script>'; printf( '</table>' );
