flot

hi i am using FLOT charts API to show data in the form of bar charts in my application. I have got requirement to show the data in bar chart and in categories with Pre Data and Post data some thing as shown in the picture like this Sample Diagram Please tell me how to take the data to plot the bar chart You need a plugin for this. Check OrderBars and then use data like: var series = []; series.push({ data: [], // your raw data bars: { order: 0 } }); series.push({ data: [], // your raw data bars: { order: 1 } }); Example: http://jsfiddle.net/ZRXP5/ My example uses Mootools, but you find the

Has anyone tried creating Normal Distribution chart using FLOT? If so, can you please put me in a right direction with some suggestions and links to tutorial? Thanks. FLOT is simply a plotting engine. If you want to create a Bell Curve, you need to feed a probability density function a series of x values and plot the resulting points. For instance I used the functions from here to create this: Here's the jsFiddle that shows my work. 来源： https://stackoverflow.com/questions/7911151/create-normal-distribution-bell-curve-chart-using-flot

I am using flot library to design stacked bar graph, wherein I am using following js files. <script src="@Url.Content("~/Scripts/charts/excanvas.js")"></script> <script src="@Url.Content("~/Scripts/charts/jquery.flot.js")"></script> <script src="@Url.Content("~/Scripts/charts/jquery.flot.symbol.js")"></script> With the following script I am defining my bar chart with rotated text of xaxis label by -90 degree. $.each(data, function (index, item) { i = (index + 1) * 2; DataValues.push({ data: [i, item.Value], color: Color[i] }); DataValues.push([i, item.Value]); TickData.push([i, item.MonthName]

but according to this: http://www.php.net/manual/en/function.json-encode.php#94157 it won't. I'm using flot so I need to have an array with numeric indexes returned but what I'm getting is this: jsonp1282668482872 ( {"label":"Hits 2010-08-20","data":{"1281830400":34910,"1281916800":45385,"1282003200":56928,"1282089600":53884,"1282176000":50262,"1281657600":45446,"1281744000":34998}} ); so flot is choking. If I var_dump the array right before I call json_encode it looks like this: array(7) { [1281830400]=> int(34910) [1281916800]=> int(45385) [1282003200]=> int(56928) [1282089600]=> int(53884)

I am pretty new to this flot API. I want to have dashed gridlines/ticklines instead of solid line both X-axis' and Y-axis'. Can anyone help me with this?? Thanks in advance! I was able to produce dashed lines for the grid's markings by modifying the library. I'm currently using Flot ver 0.8.0 First I added a new attribute under grid (around line 400), just below the markingsLineWidth: markingsStyle: 'dashed' Since Flot is using canvas to render the charts, I added a dashedLineTo() extension for the canvas using this code from David Owens. I added it just right after the color parser plugin on

I am trying to implement an automatic report generation tool for my clients . I need to create reports in pdf format and i am very much comfortable in creating graphs using Jquery flot. I just need a way to get the graphs inside the pdf. I tried using flying saucer (xhtmlrenderer) to capture the image of the graph, but it doesn't seem to help me as the graphs being created by javascript. can xhtmlrenderer capture the elements created with javascript ? or is their any other tool which can capture the image of the graph ? NIA Flot draws its graph on HTML5 <canvas> element. So the possible

Im trying to build a somewhat advanced "Flot" jQuery pluging graph. For that, I need a multidimensional object (or at least I think it is). The structure should look like this: var datasets = { "usa": { label: "USA", data: [[1988, 483994], [1989, 479060], [1990, 457648], [1991, 401949], [1992, 424705], [1993, 402375], [1994, 377867], [1995, 357382], [1996, 337946], [1997, 336185], [1998, 328611], [1999, 329421], [2000, 342172], [2001, 344932], [2002, 387303], [2003, 440813], [2004, 480451], [2005, 504638], [2006, 528692]] }, "russia": { label: "Russia", data: [[1988, 218000], [1989, 203000],

Using jQuery Flot, I can pass a null value to the plotting mechanism so it just won't draw anything on the plot. See how the missing records are suppressed: I'm looking to move to d3js , so that I can have deeper low level control of the graphics using SVG. However, I have yet to find out how to do that same process of suppressing missing records. The image below is an attempt to do this, using a value of 0 instead of null (where the d3 package breaks down). Here is some code to give you an idea of how I produced the graph below: var line = d3.svg.line() .x(function(d) { var date = new Date(d
