Option for line for spline charts to be dashes
Is it possible to set a PlotOption or Series to have a dash option. I know nothing about SVG markup but after 5 minuets of googling I found the stroke-dasharray attribute is the only thing is needed for path elements.
1 voteYou can apply it to individual series. See http://jsfiddle.net/highcharts/77FCb/.

Add style option to series data options
Allow series to be customizable through css classes. This would make it easier to customize the styling of a series, (ie. change the color) by changing values in a css class.

Allow irregular datetime xAxis (Note: irregular point intervals are already supported!)
Before voting on this feature, please make sure you understand that this does not apply to irregular data, but irregular axis. Specifying irregular data intervals is straight forward. See http://highslide.com/forum/viewtopic.php?f=10&t=9222.
Instead of fixed intervals for a datetime xAxis, implement support for specific corresponding datetime-value pairs in case there is no constant logging but sporadic or unsteady input data (e.g. temperature logging only if value has actually changed)
385 votesThis feature is completed as of Highstock 1.1. In Stock charts it is enabled by default and can be disabled by setting xAxis.ordinal to false. In basic charts it can be enabled by setting ordinal to true.

Add background options to datalabels
I am using a column chart in conjunction with a line chart. The problem is that the line intersects with datalabel of the column and makes it harder to read. See
http://i51.tinypic.com/34pj3tk.png
It would be great if I could add a white background color to the datalabel and increase its readability.

support transparent lines
I have two lines of data in a line graph that is very close in value with respect to the max and min. So close that the data lines overlay each other and I only get to see (and tooltips for) the 2nd rendered line. It would be nice if you could use transparent line in cases like this. Currently I see only a single line and two descriptions in the legend.
3 votesTransparent lines are already supported: http://jsfiddle.net/highcharts/kesck/

Support android as well as iDevices
I'm not sure if this is a big one or not, but I know that Android uses a form of WebKit for the built-in browser so it can't be too far removed from the iPhone / iPad
NB - technically you can install Opera or another browser, but most people don't
250 votesLimited support for Android 2.x since Highcharts 2.2. See http://www.highcharts.com/documentation/compatibility#android2.

Add Step Property for X-Axis Grid Lines
For example if I use the "step" attribute to only show labels for the first day of each week, the chart still draws x-axis gridlines for each datapoint instead of where the labels occur. It would be nice to have separate step property specifically for the x-axis gridlines. This is useful if you want to break up the data into weeks or months and allow the gridlines to serve as indicators of where these blocks occur (i.e. a grid line only at the start of the week or month, etc.).
Example:
xAxisGridLineStep = 70 votesThis was completed in 2.1 using TickInterval.

Highcharts as a CommonJS Asynchronous Module
Hello,
Please add the following code in Highcharts:
// Expose Highcharts as a CommonJS Asynchronous Module
if ( typeof require !== "undefined" && require.def ) {
require.def( [], function () { return Highcharts; } );
}This code would register Highcharts as an CommonJS asynchronous module.
It would make Highcharts easier to use when working with RequireJS (and other loaders).
I pasted more links for modules and loaders are discussed.

Ability to add yAxis after graph creation
It would be great to have the ability to add / remove yAxis after a chart has been created. For example, a AJAX response sends back information with new series data which require additional yAxis (or need some of the existing ones to be removed)

Simple timeline charts
A simple timeline chart that can plot a project from start date to end date with mile-stones. Milestones are specific images over-layed on the plot line. This is almost a very high level gantt that does not have linkage between tasks.

Setting opacity of scatter points too similar to area chart
When the number of points are huge its hard to view the overlapped points i think opacity feature will give a much clearer view.
2 votesIt is already implemented. When you set the color of the series to an rgba value, the points will be rendered transparent. See http://dev.highcharts.com/demo/?example=scatter&theme=default.
