flot

问题 I have a problem with jQuery flot. PHP output (not JSON): [[1, 153], [2, 513], [3, 644]] ~~ [[1, 1553], [2, 1903], [3, 2680]] jQuery call: $.ajax({ url: 'xxx.php', success: function (data) { var dataArray = data.split('~~'), dataArray1 = dataArray[0], dataArray2 = dataArray[1], plot = $.plot($('#xxx'), [{ data: dataArray1, color: colours[0] }, { data: dataArray2, color: colours[1], points: { show: true, } }, ], { series: { bars: { show: true, barWidth: .6, align: 'center' } }, grid: { show:

问题 I am plotting a dynamic barchart using flot. I have managed to plot with constant barwidth. Now I want the barwidth to vary based on the output of my analysis. I set var options = { series: { bars:{show:true, barWidth: BarWidth, fillColor: "lightgreen", fill: true } In this code, BarWidth is a javascript variable. My bar starts to plot and gets overlapped when my BarWidth changes. Does anyone has any clue how I can solve my problem? Thank you in advance! @DNS This is my plot function function

问题 I am using Flot Charts and I have 2 vectors that represent the x and y variables that look like this: var x = [1.778,1.767,2.308,2.41] var y = [35.94,35.97,36.01,36.04] The problem is that when I want to plot, the following syntaxis: $(document).ready(function () { $.plot($("#placeholder"), [d1]); }); does only allow to plot the d1 variable!! Which has the following form: var d1= [ [0,0], [1,4], [2,7], [3,3], [4,2] ]; That is fine if you have 3 or 4 points to plot, but when you have almost 50

问题 I am using flot to create bar charts like I need to specify a threshold like a line at 750(y axis) for example, to show the limit... there is one jquery.flot.threshold.js file in flot package, but i dont know how to use it on bar charts.How to do it ? 回答1: Seems there was some issues with using the threshold plugin with the current flot release version. If you just want to mark a threshold, it might be easier to use the grid markings option: $.plot($("#placeholder"), [ d1, d2, d3 ], { series:

问题 I have created a highly interactive graph. all of the interactions have been achieved without re-initiating the flot object. re-initiating the flot object causes the interactions to break, i would have liked to have done this as efficiently as possible. the interactions my graph supports are: changing visibility of individual series multiple y-axes and toggling between them zoom graph(with a reset) click and drag panning the final two features i have to add are: adding/subtracting individual

问题 I am using flot jquery library to draw charts. when my chart has a specific number of columns, I can set the x values for my points. but now I have a dynmic data. so how can I know the points of the x axis please? for example, the x axis of the first point is 1325876000000 the x axis of the second point is 1328194400000 the third is 1330360000000 the fourth is 1332838400000 but lets say that I will have 9 columns. how can I know the x axis for them please? I am printing the chart in this way

问题 My graph is as below : I want to make an same gap between each point in flot because I want to show only 6 data at the same time. So I can manage the look of my x axis data. Right now this is not looking good. You can give me another solution for making an x axis label values looking good. 回答1: The easiest way to display linear x values in flot is to provide flot with an ascending index then use this index combined with a custom label function to display whatever string you want as the x axis

问题 Good afternoon, I have looked at the FLOT website examples and googled but just cannot find anywhere with detailed steps on how to pull data from MySQL into FLOT. Currently I have a php page with a recordset that stores all records from a mysql table, columns are date, user & cost. Do I need to create a data table to display all these records in the page? When above is sorted how would I call that data into FLOT, I know its probably very obvious to any develiopers out there but I just cant

问题 I'm trying to replicate what Amazon, Trip Advisor etc are doing and showing a tooltip type interface when hovering over an average review score to show the breakdown of scores in bar chart format - on the qtip forums it's said to use Flot (my first time using it as normally use google charts) but whilst the graph renders fine on the page when I take it outside of the tooltip, as soon as I put the div within it it doesn't work. My page is: http://solicitor.info/demo/solicitors/?id=15 Can

问题 I'm trying to draw a real time graph as my mysql table is constantly being inserted with values, like a moving graph referenced from http://kalanir.blogspot.com/2009/11/how-to-plot-moving-graphs-using-flot.html The values actually come from a carbon dioxide sensor which updates the value of the table with co2 values with positions id . I changed her Math.Random to the code below: <?php $result = mysql_query("SELECT * FROM node1 ORDER BY id DESC LIMIT 1")or die(mysql_error());?> <?php $row =
