d3.js

问题 I know this question has been asked before, but I have not found an answer that works for me. I looked into https://github.com/dc-js/dc.js/wiki/FAQ#filter-the-data-before-its-charted and tried the remove_empty_bins function but nothing changed. I also tried the filter_bins function but I am getting the error message "f is not a function". I am working on a dashboard. I want the bar charts to update such that the x-axis categories are removed from the graph when they are zero and will reappear

问题 I have a graph being made by d3, with dagre-d3 sitting on top of it for drawing directed graphs. This gives me what I expect for rendering the graph: To edit the data building the graph, each element is click-able. This is fine for the cases where the edges are rendered with labels, but they don't always have labels, leading to the unlabeled edges being very hard to click to edit. These style assigned to the edges is: #visitGraph .edgePath { cursor: pointer; stroke: #333; stroke-width: 2px;

问题 I'm new to D3 and trying to do a moving average of previous and next values on my data in order to smooth it out. Currently, I have it working using the 2 previous values + the current value. It does work but 1) how would I also use the next values, and 2) what if I wanted to use the 15 previous and 15 next values? (it would be crazy to have 30 individual vars for storing all of them) I'm used to traditional javascript but lost as to how to traverse the data this way in D3. Hope someone can

问题 I'm just playing with this demo and recreating it myself: http://bl.ocks.org/mbostock/5100636 I can define a new endAngle and it'll animate just fine, but now I'm trying to animate the startAngle too. I just can't get it to work. function animateArc(newStart, newEnd) { myArc.transition().duration(750).call(arcTween, newStart, newEnd); function arcTween(transition, newStart, newEnd) { transition.attrTween("d", function(d) { var interpolateStart = d3.interpolate(d.startAngle, startAngle); var

问题 I'm doing some tests with d3.js regarding zooming. At the moment, I have successfully implemented geometric zoom in my test, but it has a drawback: the elements under the zoomed g are being scaled. As I understood it, this could be solved by using semantic zooming. The problem is that I need scale in my test, as I'm syncing it with a jQuery.UI slider value . On the other hand, I would like the text elements being resized to maintain their size after a zoom operation. I have an example of my
