Is an NVD3 Line Plot with Markers Possible?

由 馋奶兔 提交于 2019-11-27 12:19:06
问题 I'm making an NVD3 line plot that will have significantly improved clarity if I can get markers to show for each data point instead of just the line itself. Unfortunately, I haven't been able to find an easy way to do this with NVD3 yet. I also considered using a scatter plot, but I couldn't figure out how to show connecting lines between the points. A third option I considered was to overlay a line and scatter plot, but this would show each series twice in the legend and may cause other

d3.js nvd3 date on x axis: only some dates are show

问题 I have a strange issue with showing dates on a xAxis. I am generating data like this: for (i=0;i<12;i++){ date=new Date(2013,i,1); ideas.values[i] = {"y" : Math.round(2*i*getRandom(1,2)), "x": date}; } In my lineChart I want to create the x-axis like this: chart.xAxis.tickSize(12) .tickFormat(function(d) { var date = new Date(d); testarr.push(date); return d3.time.format('%b %y')(date); }); Now if I look at the chart, there are only a few Dates visible. This is why I created the array

NVD3 Line Chart X Axis Ticks Are Missing

问题 I am using NVD3 to display line chart here: http://jsbin.com/xodaxafiti/2/edit?js,output But it seems like NVD3 auto-hide some tickLabels on XAxis, but only those ticks near the edge, i.e. 2-3Oct and 27-28Oct (except the first and last tick). I know that this is an auto-reduce because when I increase the width of chart, the ticks start to show up. However I find that this reducing behaviour weird, and the lineChart does not have reduceXTicks option like multiBarChart. I want to be able to

how to set height and width of nvd3 chart

由 做~自己de王妃 提交于 2019-11-27 03:06:39
问题 I'm trying to set the width and height of a nvd3 multi bar chart programmatically using chart.width(600); chart.height(400); See the example here: http://jsfiddle.net/hPgyq/20/ As you can see this really messes up the chart. I know I can do this is CSS with: #chart svg { width: 600px; height: 400px; } but I thought this was also possible using the width() and height() functions on the chart. Am I doing something wrong here or am I mis-using the two functions? 回答1: Yes it is possible, like you

I'm using nvd3's piechart.js component to generate a piechart on my site.

How to add a click event on nvd3.js graph

由 ぐ巨炮叔叔 提交于 2019-11-26 18:18:08
问题 I am using nvd3.js and trying to add a click event d3.selectAll(".nv-bar").on('click', function () {console.log("test");}); JSFiddle How can I do that ? 回答1: I was running into the same issue and was about to dump NVD3 all together because of the lack of documentation... What you need to do is add a callback function to addGraph(). Also note the d3.selectAll() instead of d3.select(). Good Luck. nv.addGraph(function() { var chart = nv.models.multiBarHorizontalChart() .x(function(d) { return d

问题 I have a line chart and every time the page refresh it changes the data, which is great but I need to to refresh by a user click. This is because there will eventually be other input fields on the page and refreshing the page would destroy their current session. jsfiddle - http://jsfiddle.net/darcyvoutt/dXtv2/ Here is the code setup to create the line: function economyData() { // Rounds var numRounds = 10; // Stability of economy var stable = 0.2; var unstable = 0.6; var stability = unstable;
