flot

问题 I am building a Rails 3.2.11 app with Flot. I want to render my Flot charts in PDFs using Prawn. My Flot charts render in the browser fine. I can create Prawn PDFs fine (though not with chart images yet). I want to use the Flot canvas plugin to render my axes, etc. on the canvas so they are included when I Ajax the image data to the server using the .getCanvas() and .toDataURL() methods, but I can’t seem to get it to work. I am using jquery.flot.min.js 0.8.0 and jquery.flot.canvas.min.js (no

问题 I need a way to align tick marks on two separate axis, while being able to control the "step" value (value between tick marks), where both axis start at mark 0 and end on a different maximum value. Why this problem: Flot, the JS charting package has an option to align tick marks, but when I do, I cannot control the step value. I can however control the step value directly, but then I lose the ability to align tick marks. I can however revert to defining my own max and step values, to get what

问题 I'm trying to make a genealogic timeline with jquery.flot. I want to display the right label when i'm hovering a point, i.e. when i'm hovering the marriage point of a person, the label "marriage - marriage date" appears. But visibly, i'm not able to build an array of labels as it's possible to do that for data. Just a bit of the code : <div id="placeholder" style="width:800px;height:300px"></div> <script language="javascript" type="text/javascript"> $(function () { var data = [ { label: [[

问题 I have a set of data that I'm plotting as a scatter graph which has both positive and negative values on both axis. When I plot this in Flot, the axis are draw at the bottom and the left by default. Is there a way to make it draw the axis through the center of the graph? @X=0 and Y=0? In other words, instead of this: I want something like this: 回答1: That isn't possible in the default flot. I'm sure it could be hacked in if you wanted to dig into the source, but flot by itself only supports

问题 I'm trying to display the customized label inside the bar chart. No idea on how to do this.. Please help me. Label should be displayed inside each bar 回答1: You just specify this in Series config... It's working fine for me: label: { display: 'outsideEnd', field: 'data1', // field name orientation: 'horizontal', // or 'vertical' color: '#0000FF', 'text-anchor': 'middle' }, 来源： https://stackoverflow.com/questions/6843188/display-label-inside-stacked-bar-chart

问题 I have DB relation that holds information that I wish to display. each record holds a numerical value, and a 'name' that looks like '20140325_064532'. The order of creating the records doesn't matter, and so I wish to present the numerical value on the y-axis and the x axis to have: to have constant margin between ticks. to present the data based on 'name' order (lexicographic). the x-axis label shouldn't present all the values, but "selected ones", such that no overlapping should be

问题 So I am having an issue with Flot. I have all the data right, but the only problem is my data doesn't stack. I have stack: true, but what am I doing wrong? Here is the output of the three arrays in php [["Lifting 1",4],["go 2",0],["Hub",0]] [["Lifting 1",1],["go 2",106],["Hub",92]] [["Lifting 1",50],["go 2",24],["Hub",46]] <script type="text/javascript"> $(function() { var d1 = <?php echo json_encode($dataset_inb_dmg01); ?>; var d2 = <?php echo json_encode($dataset_inb_dmg02); ?>; var d3 = <

问题 I am new to flot, but managed to set my time graph pretty quickly. Here is my time based plot: $.plot("#placeholder", [d], { xaxis: { mode: "time", minTickSize: [1, "month"], min: (new Date(2008, 05, 20)).getTime(), max: (new Date(2014, 05, 27)).getTime() } }); when the user clicks a button I want to change the plot to show only a part of [d] - for instance, if [d] contains data for 2013 and 2014, I want to show only 2013. They have such example in flot examples (http://www.flotcharts.org

问题 I'm trying to draw a monthly bar chart using Flot library. The alignment with the month center is completely wrong with the x axis. I've created a jsfiddle to show the problem. Intuitively when giving bars: { show: true, fillColor: '#4682b4', barWidth: 15 * 24 * 60 * 60 * 1000, align: 'center' }, I suppose the bar should align with the tick on the center, but is not! The result I'm expecting is the following: Thanks a lot! 回答1: Instead of showing just the month, include %d in the time format
