flot

问题 I used to draw this kind of chart (one vertical axis, one horizantal axis): Now i have been asked to do this kind of chart: as you see, the problem with the ordered chart that it contains (two vertical axis, one horizantal axis). My question does flot or any other jquery library able to do that please? 回答1: See the flot example here on multiple axis. Minimal example: $.plot("#placeholder", [ { data: d1 }, { data: d2, yaxis: 2 } // set second series to use second axis ], { yaxes: [ { min: 0 //

问题 I know there are several posts about this but I think I'm missing something. I'm returning the data below in an ajax call but it doesn't seem to be in the right format for FLOT. Is there a better format to return the data in or what should be changed for FLOT to recognize it? TIA <script type="text/javascript"> $(document).ready(function() { // Add the page method call as an onclick handler for the div. $("#Result").click(function() { $.ajax({ type: "POST", url: "WebTest.aspx/GetData", data:

问题 I'm using flot (flot on github) to draw a graph with the following time series data: [ [1357171200000, 1], [1357344000000, 1], [1357430400000, 2], [1357516800000, 2], [1357689600000, 3], [1357776000000, 1] ] As you can see there are some points in the graph wich show the sales for the given day. My json response doesn't contain sales count / data for days where no sale has happened. For example the 04th of January. How can i configure flot to draw the missing days on y-axis at point zero

问题 From the example here, I kind of know how to create a Flot graph that shows tooltips when hovering. But the examples only show to how to display tooltips containing the x value, y value, label, etc., and I can't figure out how to create more customized tooltips. Is there someplace I can attach custom data, that I can access when creating the tooltip? For example, to simplify, let's suppose my code looks like: var d = [ { label: "Fake!", data: [ [1290802154, 0.3], [1292502155, 0.1] ] } ]; var

问题 I am using jQuery/FLOT to draw a graph, I would like for the user to be able to download a PDF version of the graph. I am writing the PDF using ColdFusion. After creating the graph I then send the html of the graph div, via ajax to a CF script that uses cfdocument to write the pdf. The problem is that in the PDF, it only displays the axis and labels, not the actual graph data. Does anybody know of a way to get the actual image that is dynamically created on the canvas? 回答1: I don't think this

问题 Can any body help me to find out, how to print dynamic graph as example generated by flot. I tried this one but it's printing whole page, but I want only graph portion. function printGraph(){ $('<img src="../images/button_refresh.png" alt="Print Graph" style="">').appendTo(controlholder).click(function (e) { //Canvas2Image.saveAsPNG(document.getElementById('placeholder')); //canvas.toDataURL("image/png"); window.print('placeholder'); }); } 回答1: This article describes how to copy the canvas to

问题 I want to be able to use the legend of a flot graph to turn on/off the series of my graph. I found the examples on the flot site and have used the Turning series on/off and Labelformatter from the API to build what I have right now. I can put checkboxes next the legend elements and add a click event to them and its fires. But that calls the plot function again and resets my checkbox values. I have included the full jquery function, sorry its a bit long. <script id="source"> var jsonPath =

问题 I have drawn a pie chart using jquery flot pie, but its edged at the top and bottom are somewhat slightly cut I didn't change anything (except data) from when I bought this Wrap bootstrap theme and as you can see it also has this problem in all pie charts. What could be the reason for this to happen? 回答1: Apparently this got fixed with a newer combination of plugins: v0.7 to v0.8 of jquery.flot.js and v1.0 to v1.1 of jquery.flot.pie.js 来源： https://stackoverflow.com/questions/21421614/jquery

问题 Using Flot to create a whole bunch of pie charts across a site. I'm finding that if a chart is defined, but on a given page the div it's assigned to isn't there or doesn't have the height/width set, that chart and all those defined thereafter do not display. The issue is that some charts are needed in some pages and not in others. I'd like to define the charts all in one place and place them in their appropriate views as needed, but with Flot Pie it seems that as soon as the script comes up
