Flot: How to keep x and y axes the same scale?

由 ≯℡__Kan透↙ 提交于 2019-12-10 10:16:21
问题 I want to plot on a standard Cartesian plane, so 1 unit on x axis has the same length as 1 unit on y axis. I also use the navigate plugin to zoom and pan. Is there anyway I can have this constraint? can't find anything about this in Flot api. Thanks, 回答1: I had to do something similar and this was the first test: fiddle The main point is that you set the max values for the axis in the same ratio as the width and height of your placeholder div: options.xaxes[0].max = options.yaxes[0].max * $('

How to render this bar chart with flot

问题 Can you render a bar chart like this using flot? Do I need to create the dataset manually to get this result, instead of using mode: 'time' ? 回答1: Actually pretty easy to produce using flot. var options = { series: { bars: { show: true, barWidth: 15778463000, // 1/2 year in milliseconds align: 'center' }, }, yaxes: { min: 0 }, xaxis: { mode: 'time', timeformat: "%y", tickSize: [1, "year"], autoscaleMargin: .10 // allow space left and right } }; $(function() { $.plot($('#placeholder'), [[

What is the format of jQuery Flot data when passing in the data as variables

I have been trying to create a jQuery Flot pie chart, but I can't get the "data" parameter to work. I have 0..6 values that should total to 100(%), and these values need to be added individually, one label value pair at a time. All of the examples I have seen assume that the data values are hard wired, and unfortunately that is not the way the real world works. I need some real world examples of how to construct the label - data pairs that Flot uses. I finally got it working when I realized that the data is supposed to be in jSON object notation. The old light bulb may be dim, but not entirely

Add or highlight a single points on a jQuery flot graph?

I've already drawn a flot graph using some data: var plot = $.plot($("#placeholder"), [{ data: data, }], { series: { points: { show: true } }, grid: { hoverable: true, } }); Now I'd like to highlight a single point on the graph, when a user hovers over an item elsewhere on the page. I found this question , which explains how to totally redraw the series from scratch, but is there a way to highlight a single point? Or add a new point in a different colour, which would have the effect of a highlight? NB: when the user hovers over the relevant item elsewhere on the page, I will have the x and y
