I am using the zoomable sunburst example but I am struggling trying to add a text to the center of the diagram and still make it zoomable.
The idea is that the text in the center will change when I click on a certain arc indicating its length. It seems that the properties of the mouseclick and mouseover dissapear.
This is what I have tried:
path.append("svg:text")
.on("click",click)
.style("font-size","4em")
.style("font-weight","bold")
.text(function(d) { return count_function(data); });
Can someone help me understand how to display the text in th center of the chart without losing the click functionality?
Maybe an easier approach would be to select the "g" that represents the circular centre and add text to it once the chart was been displayed. I have tried this but I am unable to successfylly select just this element (sorry I am new to D3), so back to square one.
It looks like you're trying to insert a text element inside a path element. Try something like this:
svg.select("g").append("svg:text")
.on("click",click)
.style("font-size","4em")
.style("font-weight","bold")
.text(function(d) { return count_function(data); });

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 created a heatmap and sparklines next to the heatmap.
HERE the Plunker
Now I would like that when the user hovers over a cell of the heatmap, a red dot is displayed on the corresponding sparkline.
On the other hand, when the user hovers over the sparkline, the corresponding cell in the heatmap is highlighted.
I hope it's clearer with some drawings:
I thought I could change the code at this point:
var cells = svg.selectAll('rect')
.data(data)
.enter()
.append('g')
.append('rect')
//...
.on('mouseover', tip.show) // <- HERE
.on('mouseout', tip.hide);
I should keep track of the rectangle on which the mouse is located and somehow pass this data to the piece of code that controls the sparkline.
But I don't really know how to do it and I have not found similar examples.
Thanks!

add this liblary:
<script src="https://code.jquery.com/jquery-3.1.0.js"></script>
To solve your problem, you need understand the concept,
The D3 can holding data when you put on it
The D3 can select base on class and id
The DOM element can hold attribute (Ex: attr-id)
Scale linear can be invers, that mean if you have domain you can have range and if you have range you can have domain
Element that draw with D3 is updatable & deletable
understand the liblary you use (d3-tip)
What i Change
i add class and id to element i want to select
if i want to use data, i save data to data-attribute
i make function to track my mouse on Line-chart, and invers it to get value
i draw object tip i want to use
read the code if you want to understand ask me which line you dont understand, if you need explanation
I have the following donut chart here in d3.js
Please see here: <https://jsfiddle.net/jz9z9hw1/>
I am unsure of how to add text right in the centre of the donut. I'd like it to say "Test System 1".
Also, how does one go about adding text within the arcs? So, it would display the actual numbers?
Just add a text element to your SVG, like this. I added this to your fiddle, and it added the text right in the middle:
var text = svg.append('text')
.text('Test System 1')
.attr('text-anchor', 'middle')
I have encountered an issue with the C3.js tooltip not being triggered after I fill the areas between two lines using d3.svg.area. Fiddel:
Tooltip disabled by areas filling in between two lines
As we can see from the example, when we hover to the point outside the area, the tooltip will show up; but when we move to the point inside the area, nothing will be shown. I assume that the d3.svg.area has been impacting the C3.js tooltip behaviour, but what/where exactly? Any one got ideas about this?
I also tried to set the z-index of the area to be smaller than the line and circles, but it does not help at all.
I added the code below and set breakpoint, and it was not hit when hovering to the first point.
tooltip: {
format: {
title: function(d) {
console.log(d);
return d;
},
} }
Any help is appreciated. Thank you.
We have requirement to add drop down with axis label so that user can change the data from there.We require this drop down box effect on only specific label.
One approach we have tried is to add svg:image with label and the functionality is working fine but the other label is having the down arrow image that is not required. So can anybody help me out how I can select only one label? Actually there are multiple labels and its index is getting changed on chart update. Please find below code which is working for adding images to all labels.
e.g.
g.selectAll('.nv-x.nv-axis').selectAll('.tick.major').append("svg:image").
on("click", click)
.attr("xlink:href", "images/top-bar-logo.png")
.attr("width", 20)
.attr("height", 20).attr("x", -20);
You can use the filter() function to select the ticks that you need to append the image to. The documentation I've linked to has a few examples -- you might be able to do it without filter() by passing a different selector to selectAll().
