d3: Plot as a cumulative graph

问题 Does d3 have a built in method to plot a data set as a cumulative graph? For example, if the y values are: [2, 4, 2, 2] , I want them to actually be plotted as: [2, 6, 8, 10] . Does d3 have a way to do this or would I have to traverse the data set and do this manually? 回答1: You can check https://github.com/mbostock/d3/wiki/Arrays for more info but I think you can use the reduce() function here. i.e: [0, 2, 4, 2, 2].reduce(function(previousValue, currentValue, currentIndex, array) { console

Fit the cumulative percentage line to the sorted histogram output with d3 for a pareto chart histogram

问题 This is what I have so far: https://gist.github.com/daluu/fc1cbcab68852ed3c5fa and http://bl.ocks.org/daluu/fc1cbcab68852ed3c5fa. I'm trying to replicate Excel functionality. The line fits the default histogram just fine as in the base/original http://bl.ocks.org/daluu/f58884c24ff893186416. And I'm able to sort the histogram in descending frequency, although in doing so, I switched x scales (from linear to ordinal). I can't seem to map the line to the sorted histogram correctly at this point.
