I need to generate tool tip on area graph using Raphael.js. But tool tip has be shown on hover at particular x,y coordinates only( position is important since it is a multi area graph).
I am able to generate this area graph and tool-tip as well.
There are multiple lines on tool tip and each should have separate styling and not same styling.
I am unable to rotate the tooltip by 90 degree and there is a problem since the tool-tip keeps shifting downwards when text size changes.
So are there any way where can style each text on each line differently and keep the tool-tip at correct place?
This issue is resolved.
Since Grafico was really tough to customize I used Jquery FLOT library for my requirement .
I am able to do any required customization in FLOT and FLOT is very fast and easy to use with so much support available on the FLOT site.

Creating Sparkline line graphs.
http://jsfiddle.net/gwatts/PfzXg/
// Draw a sparkline for the #sparkline element
$('.sparkline').sparkline(values, {
type: "line",
tooltipSuffix: " widgets"
});
The jFiddle example is not the best, but I think it illustrates the point.
The default behavior is to have the tooltips appear once the mouse hovers over the value. The "5 widgets" tooltip appears when you hover over the point.
Is it possible to have the tooltip always appear?
I wanted to make a graph that is bigger and has static data labels (tooltips), but I don't see any mention of it in the documentation.

Frequently Asked Questions
Why are there no axis labels/markers?
Sparklines are intended to be small enough to fit alongside a line of text, to give a quick impression of a trend or pattern and thus don't have the paraphernalia of full sized charts. As of version 2.0 you can mouse over the sparklines to see the underlying data.
It is necessary use Sparkline library in your project?, if you want a big chart and labels you have other option like http://www.chartjs.org/samples/latest/.
How to integrate raphael charts with jquery qtip since qtip provides very nice configurable tool tips out of the box?.
I have found the implementation of the stacked area graph in this url http://grafico.kilianvalkhof.com/documentation/#stack . When I started playing with this implementation for the customizing the tool tip on this area chart. But things like applying styles on the text and changing the orientation of the tool tip seemed very difficult .finally I managed to change the text and color of the text on tool tip ,change the size and more . But all customization resulted in tool-tip drifting from its position when the size of the text is increased. But I want all the features available in QTIP for the tool tip .Please any body has clue on this? all ideas are welcome Below is the graph i have generated with the tool tip
I am able to solve this problem by using Jquery FLOT instead of Grafico and Raphael
Jquery FLOT is really cool, easy to use and customize and it has lot online help.

I am using the Zoomable Pack Layout provided on the D3 website: http://mbostock.github.io/d3/talk/20111116/pack-hierarchy.html
All labels of the circles are displayed when the layout is displayed.
The problem is that for small circles which are close together, the labels overlap. I would like to know if there is a way to hide the overlapping text of the labels?
I have read about "foreignobject", but if this is the answer, I am not sure how and where to incorporate it in the code.
You could restrict the display of text based on either the level of the hierarchy, the radius of the circle or a combination of both. Both are in the pack output. Use titles for hover detail.
I'm looking for a charting library that can draw heatmap charts, and has the option of displaying column label text vertically (allowing me to fit lots of columns on the screen regardless of the length of the labels)
Ideally the library would be free for a charity/educational organisation.
Here's an example of a simple heatmap with vertical labels:
That chart was created using FusionCharts, which is not suitable as it is a flash-based product and is expensive to license.
You could always roll this yourself. Most of the table can be generated using ordinary HTML, with the exception of the vertical labels at the bottom. You could tackle that with Rafael, a JavaScript library that allows you to draw on an HTML canvas. Drawing rotated text is actually available out of the box so it won't be hard to implement.
I think what you are looking for is also called a TreeMap (in some circles anyway).
Check out thejit.org
Under the demos checkout the treemap and the icicle chart.

I am trying to add the actual value of all the bars in my chart to the
end of each bar. I want this to either replace, or to add to the tool-
tip functionality.
I see that this is possible in the image chart, it is the
functionality described in the following link that I wish to
replicate:
http://code.google.com/apis/ajax/playground/#image_bar_chart
I am wondering if this is possible in the Javascript based version of
the bar chart?
Many thanks,

It looks like there's no built in functions to draw text ad-hoc on top of google's different charts. Behind the scenes, it's generating SVG so you could try to insert some valid SVG on your own.
Another option would be to use a more flexible (but less featureful) library like raphael.js:
