Could you please help me in adding tooltip in stacked Bar chart. I have created Fiddle Link
i want to add tool tip on each bar chart ie. Each bar should show tool tip for each color. How can i do that.

Thanks in advance
You can append a title element under each rect and give it a text value of whatever you want the tooltip to say.
Here's a related question showing more details: How to add a tooltip to an svg graphic?
What exactly you want to show on tool tip? Is it data value or some text?
You can add
.append("svg:title")
.text(function(d){
return yourData;
}
});
This function should work for you and put the variable name where you are getting corresponding values of bars.

I am trying to build a D3 bar chart visualization that can be updated using a drop down menu.
So far, I have successfully created the bar chart and the drop down menu such that when I change the selection in the menu, the bars are updated to their new values.
However, I am having problems with the bar labels updating appropriately. Even though I include the same .exit.remove() function for the labels as for the bars, the old labels remain on the newly updated chart.

Apologies for the links. I'm new to JSFiddle, and I couldn't figure out how to easily transfer my example.
You forgot to add class attribute while appending the text
You also need to change the text while updating
Hope this helps
bartexts.transition().duration(250)
.attr("y", function(d, i) {return yScale(d) - 10})
.text(function(d) {return d});
I have a stacked bar chart as follows:
I want to draw a horizontal line that goes through all the bars of a specific color on hover. Basically, if I hover on the following purple/mauve color, I want the following:
I looked alot in online as well as the documentation, but couldn't find anything.
Any help is really appreciated; thank you!
In theory you should be able to pre-render 5 line charts in addition to your stacked bar chart. Give each line chart a unique id or class html attribute, and each segment of a specific color needs a corresponding html classname, eg 'chartSegmentPurple' (actually it would be better to name the class based upon what the color represents, eg 'chartSegmentEconomicInequality'). Keep each line chart hidden. Give your chart an event listener for hover, then in the event handler get the classname. Use the classname to make visible the corresponding line chart.

I know this is old bu this is what helped me in the same case as above:
barSizeRatio: 1
I'm using D3 to display multiple bar charts (30+ charts) similar to the example here: http://phrogz.net/js/d3-playground/#MultiBars_HTML As the user hovers over a bar I want to change the title of just the chart the user is interacting with, with information about the value the user is hovering over.
So if I add something like:
bars.on('mouseover', mouseoverfunc);
function mouseoverfunc(d, i) {
// update the title just for this chart..not all charts
a.select("h2").text(function (d) { return "hello"; });
}
So knowing the mouseover is on the bar [d3.select(this)], how do I select the parent so I can change just the title of one chart? There is a very similar example here: http://mbostock.github.com/protovis/ex/minnesota.html that I'm trying to replicate in D3
Thanks.
The easiest way is probably to assign an attribute to your title divs that let you find them with a select statement, something like:
d3.select("[parentBarChartID="+d.id+"]")
in your mouseoverfunc.
Alternatively, you couldmake your DOM elements hierarchical such that you can traverse using this.parentNode.childNodes, looping over all children until you find the title node (see how to loop over child nodes here.
I believe that the following two examples should show you how to individually select any bar and trigger a callback that selects any specific item...
"Multiple D3 Horizontal Bar Charts Mixed In With HTML Layout Constructs"
"Multiple D3 Vertical Bar Charts Mixed In With HTML Layout Constructs"
You'll notice in the callback functions "synchronizedMouseOver" and "synchronizedMouseOut" that they trigger the change of multiple objects on the SVG canvas... An individual bar, a legend bullet, and a legend text string. You would use the same methodology to change a chart title.
I hope this helps.

I want to change the color of the area chart after it is initially rendered.
In the JSFiddle demo after clicking the button you can see the color has changed when you either mouseover the data point or toggle the display by clicking on the legend to hide and then show again.
In both of these the main area color has not updated but the data points and legend has.
JSFiddle Demo: http://jsfiddle.net/simonweston/tLwy5/
Any help would be greatly appreciated.
You can change it dynamically but you need to manipulate the SVG DOM elements instead of the chart object:
$($('.highcharts-series').children()[0]).attr('fill','blue')
Produces:
I have also tried changing it without luck, the only way is to re-create the chart as seen here
