Tooltip data interpolation
If I've got a sparse dataset (e.g. to save space, duplicate data points are omitted), a line graph still represents the data accurately, however the tooltip only appears over the actual data points.
Would it be possible for the tooltip to interpolate the data at the mouse pointer's position so as to show a value whether there's an actual data point there or not?

Add an event for legend item hovering
You might add mouseover/mouseout events to legend items. This event should provide the index of the legend item.
That gives the developer more control about what to do when hovering legend items and gives him the control to devide whether a tooltip should be shown or the series should be highlighted or whatever.
A common use case might be to show tooltips when hovering legend items --> http://jsfiddle.net/ArmRM/481/

Show value in legend
Today one big problem is that when we have a Stock chart with around 5 series & data for about 3 years, the tooltip hides important data.
It'd be great to have an option to show the values aside the legend items instead of the tooltip like http://www.amcharts.com/stock/multiple-datasets/. That way we can make sure that the values are shown & nothing in the chart area is hidden from the viewer.45 votesIn the Highstock you can position the tooltip absolutely, which provides a similar effect: http://jsfiddle.net/highcharts/j7BSy/

To use a true legend, a plugin is needed. See http://jsfiddle.net/highcharts/DVvdZ/ -

Support multiple legends
I have a chart where I mix and match different colors and stroke styles. It would be nice to have the possibility to have multiple legends, or at least the ability to create groups inside the legend, so I can better separate the meaning of the color from the meaning of the line style.

Support of Network diagrams. Much similar to the Topology diagrams in Networking world
Addition of support to Network diagrams would make this utility perfect and complete.

Set Axis's top and height at runtime
In order to display two panes (price pane at top and volume pane at bottom) correctly when chart's container resizing, it would allow to set axis's top and height at runtime.
Or another way you can do is to set axis's top and height value in percentage unit.

Sort stacked columns by total
Then Pareto graphs would look great even as series are added and removed.

series.compare should switch to absolute values for single series in a graph
We have a user requirement, inspired from Yahoo/Google finance, ie:
In case of single series( read first series, eg stock) they would like to see actual values on Y axis.
but whenever a new series is added they would like to switch to compare percent mode and vice-versa.42 votes -

Progressive data rendering with zoom event
Large data sets may well include more data than can be presented, given the pixel size of the display. When a user zooms in on the data, more information would then be needed to display detail data.
A progressive mechanism would be useful to allow more detail to be requested and sent to the client via an ajax call, triggered from a zoom event. This progressive rendering might show a lag on zoom, but in some cases this lag would be preferred to a long delay for initial data display for very large data sets. It might also perform better…

HighStock Navigator as a standalone component.
Hi,
Please make HighStock navigator a standalone component.
It could have several usages besides driving the HighStock time:
- immediate time selection/change for any web application - much more intuitive than just a Date + Time picker. Right now there's nothing similar: you have it, it's user friendly, but it' just not standalone.
- use to zoom in and out several HighCharts (not HighStock) in the same page. Right now there's only a mouse based zoom (with and selection), but that's not very efficient when using more than one chart in the same page. Syncing those charts is still not…38 votes -
Create some form of tree / node linking chart
Highcharts doesn't currently appear to have any tree / node linking chart types. A few examples would be:
- Dendograms: https://en.wikipedia.org/wiki/Dendrogram
- Hierarchical clustering: https://en.wikipedia.org/wiki/Hierarchical_clustering
- Minimum Spanning Tree: https://en.wikipedia.org/wiki/Minimum_spanning_tree
The above chart types vary in their purpose and how they are constructed. But this request is simply to have some form of tree / node linking chart capabilities in highcharts.
Once it becomes possible to chart a basic tree or hierarchy structure, it may be easier to extend functionality to create further chart types along the same thinking.
Plot.ly currently offers both dendrogram's and tree plots within their python API. But of…

Post Charts to Facebook
It would be great to be able to post preview images of charts to Facebook, so that when a user shares a chart on Facebook, it shows an image instead of just a link.
36 votesPosting a chart to Facebook would mean that we ad a backend to store the chart and to communicate with Facebook. Highcharts JS is a client side charting library, so this goes beyond its reach. It is up to the implementer to provide a backend for it.
Highcharts Cloud, however, has this capability. See http://cloud.highcharts.com.

Use requestAnimationFrame instead of setTimeout
All animations in Highcharts use setTimeout. A new feature, requestAnimationFrame (https://developer.mozilla.org/en/DOM/window.mozRequestAnimationFrame) optimize all animations (CSS3, SVG, JS) to have a smooth rendering.
