Title says it all: I prerender a chart on a server using dc.js and node.js and return the SVG back to the client. The SVG looks like the following: https://gist.github.com/anonymous/e2f7d237bcc784cfe97d
At the client, I simply write the returned SVG into a div
var svg = prerenderChart(...)
document.getElementById("dc_plot").innerHTML = svg;
The result looks pretty okay, the only problem is that the "track lines" are not appearing when I hover a data point. It should look like the following: http://s2.postimg.org/jqs37yird/3837933.png
I can see in the SVG, that the blue dot and the dotted grey lines are there, but they will not be set visible on a mouseover. I suppose it has something to do with dc.js's mouseover event listener which is not bound to the SVG in dc_plot (dc.js, d3.js and crossfilter.js are added at the client side). Of course I could write my own event listener but maybe there's an easier solution?

We need to make it move like here.example The code is complex there, I can't figure it out.
I wrote the code my code, but I don’t understand how to make the tooltip move horizontally not behind the mouse, but near the nearest horizontal mark (as in the example)
It is not yet clear where the text above the bold text in the tooltip comes from. How to remove it so that it looks like in the picture?
How do I make the title of the tooltip match the label on the X-axis?
There are many ways to accomplish this. The way I typically do this is to create a series of SVG elements -- such as circles or rects -- using the same scale and data as the paths.
You can make these objects visible or invisible. Either way, you can attach mouseenter, mouseleave events to each to render and populate the tooltip.
I want to use exactly this d3 donut chart.
This 3d chart
However, instead of showing percentage, I'd like to show the raw datas that I am providing.
Ideally, the percentage could be shown (as it is now) and I could show the raw datas for each donut part using an onmouseover tooltip!
Can't make it work.
Thanks a lot for any help!
Are you looking for this,I update the fiddle with tool tip,
Initially add a div to the body i.e.
var div = d3.select("body").append("div").attr("class", "tooltip");
then whenever user makes a mouseover or mousemove on the paths/arcs do the necessary.
have a look in http://jsfiddle.net/Q3dhh/25/
So, in nvd3 charts, clicking on a legend entry basically filters that out of the chart window (for instance in the case of area charts). I want to invert this functionality..i.e. show the particular chart when its corresponding legend is shown and hide all the others...is there a way to do it?
It is similar to what happens when user hits the chart itself (i.e. only the one that is clicked is expanded and rest of the streams hide).
I am referring to this example: http://nvd3.org/ghpages/stackedArea.html
There's a radioButtonMode that should do exactly what you want. You should be able to set this on the chart, i.e.
chart.radioButtonMode(true);
I never have much luck trying to put code into this text area.
My question is how to modify the on mouseover (jsfiddle) so that I start with (DHTML) text and when you mouseover it arcs the text, then mouse out it returns to the original position. Even a link to a site with help.
Use one of the following methods to generate the arc and the text:
SVG
CSS3
Raphael.js
CSSWarp generator
Then bind a mouseover event to the container of the text content to produce the desired effect.
I have an annotated timeline chart that gets new data over ajax. It's working fine, new points come in and I redraw the graph. My graph has two lines, so there are two labels in the legend on top. For whatever stupid reason, every single time the graph is redrawn, the legend labels swap places! So it will say
Foo 5.2 Bar 3.6
And then I'll refresh (and there will be no new data, so the call to redraw is 100% identical to the previous one) and now it says
Bar 3.6 Foo 5.2
In the respective red and blue, of course. What on earth would possess the applet to do this? Is there any way I can control the order of legend labels? I couldn't find anything about it in the official documentation.
Try using google.visualization.DataTable. For example:
dataTable = new google.visualization.DataTable({cols:graphColumns, rows:graphRows});
chart = new google.visualization.AnnotatedTimeLine($('#chart_div')[0]);
chart.draw(dataTable)
I use it this way and don't have any problems with my legend values.
