Keep Sparkline Tooltips from Hiding - javascript

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 display all percentages on Google PieChart

I'm facing two problems.
How can I make sure that the whole legend can be seen under the graph? Indeed when the legend is too big three points are added.
My other problem concerns pie charts. How to make all the percentages appear on the graph, by default it puts them only when the place is sufficient on the graph?
Bar Chart problem
Pie Chart problem
Thanks you
Bar Chart Problem : Its the default behaviour. The 3-dots is called ellipses. It is used to truncate the strings to fit the in to the containing box/div. For more info, refer this. This workaround would help you if you wish the axes labels are need to be shown full. In case legend values, please refer this.
Please refrain rom using such long names for the axes as it affects the UX.
Pie Chart Problem : Its the default behaviour of Google Charts to show the values only if the values are sufficient to fit in the place. As a workaround, you can display all the values, in the chart using the option {legend : "labelled"}. Thanks to this Google Forum.

Chart.js Axis Label Tooltip

I'm using chart.js within a grid system for a project.
The grid system allows users to make relatively small charts.
In this situation we truncate the axis labels based on fixed breakpoints against the grid size for that axis.
However as a requirement for this work the user needs to be presented with a tooltip when hovering over the truncated axis label.
Is this at all possible with Chart.JS? Either naitively or through a plugin?
I'm assuming if hooks are available ill have to use a callback method, like with data-points, to get the un-truncated label.
Ive looked through the documentation on Tooltips and couldn't find anything for Axis label tooltips.
To clarify
Is it possible for Chart.Js to show a tooltip just for the Axis Labels independently to tooltips shown when hovering over a data-point?
In the following fiddle the YAxis label has been truncated as it is too long for the space. (This would be done pragmatically by my code in production). What i would like is for Chart.js to render a tooltip when the user hovers over that axis label and provide it with the full un-truncated label.
Ive seen the following option block, however it mentions nothing in the docs about tooltips for this option. I'm beginning to fear its not possible. Just after confirmation or not of that really.
scaleLabel: {
display: true,
labelString: 'Some Axis...'
}
Thanks

tooltip issue in raphael js for area graph

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.

Highcharts highstocks - Dual chart axis issue

Looking through the documentation for Highstocks, I found this example:
Shown here is two series on the same chart, therefore with a linked range selector - this is really really useful, but I wish to display something different which is proving to be very difficult.
What I'm looking for is a normal line graph on the top series, representing data plotted onto time (almost like in this example), but a bar chart or horizontal candle chart in the lower graph, representing one or more timelines.
I've drawn an image of what I'm looking for:
I apologise for the crude drawing, but hopefully it shows what I am aiming to achieve: standard graph on top, bar/candle on bottom.
I have attempted various techniques to render this, but I can't find a way to have both series drawn on the same timescale, linked with the same range selector.
In case it helps, here's a starting point on JSFiddle, with all the unnecessary code removed: http://jsfiddle.net/g105b/8JhXv/
and a link to the original demo: http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/stock/demo/candlestick-and-volume/
Answer taken from official Highcharts forum
it is possible, but with some limitations. In the fact you want to show gantt chart. Bar charts aren't possible in your case - bar chart = inverted whole chart (yAxis becames xAxis, etc). Instead take a look at example for gantt chart: http://jsfiddle.net/highcharts/r6emu/
You can combine them into one, ane effect: http://jsfiddle.net/8JhXv/1/
About limits:
tooltip fo bottom chart is availabe only when you mouseover start and end date
bars are on lines, not between them

Which javascript or JQuery charting tool can I use to create heatmap charts with vertical column labels?

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.
At this url you can find what you are looking for heatmapjs
