Up and Down Border Colors on Candlesticks
You added upColor along with regular color on Candlesticks - this is a great start. However, almost all Candlestick charts offer differing border colors as well, an upBorder and downBorder if you will. If you would add this so we could base it on a real stock chart's open, high, low and close this would be a TREMENDOUS improvement.

wind barb and vector plot
It would be very useful to be capable of plotting wind barb and vector arrow as a type of plot. This would allow us to plot 2 dimensional data (value, direction) alongside other line or column plots (i.e. temperature, pressure, etc.)
Example:

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.

An option for preventing a chart from interfering with iPhone scrolling
Charts capture scrolling events on an iPhone or iPad, making scrolling the page by flicking on the chart area impossible. An option for changing this behavior would be desirable.

Angular 2 support
It would be nice to have native Angular 2 support. So far, it's a little bit complicated to implement Highcharts with Angular 2 (without relying on 3rd-party plugins.

overlaid column chart
The current stacking options are: null to disable, "normal" to stack by value or "percent".
Another visualization is to overlay the columns (usually requiring the use of transparency).
As a comparison, please see the stacking options offered by Flex:

Building stack bottom up
Hi,
We want to add stacks in reverse order without touching legends order. I tried to dig into code and found that while (i--) unconditional
you can add new property so that generic solution can be applied
Code as in 3.0.7
/** * Build the stacks from top down */ buildStacks: function () { var series = this.series, i = series.length; if (!this.isXAxis) { while (i--) { series[i].setStackedPoints(); } // Loop up again to compute percent stack if (this.usePercentage) { for (i = 0; i < series.length; i++) { series[i].setPercentStacks(); } } } },
Proposed code with new property

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.

Fix spline plots to draw a better generalized line.
Current spline plots can be unintuitive when your dataset isn't quite a perfect curve. A dataset of 10,10,10,0 shows a huge spike in the line right when it really shouldn't exist.

Add a built in table parser
A built in table parser would allow that the data be defined in a table in the HTML page. If JavaScript is disabled in the browser, the table will still show.

allow line charts to handle missing data without interpolating
When drawing a line chart, one should be able to specify the interval between x axis points and whether to interpolate or not at missing x axis locations. That way, if [x,y] data is missing some x locations, we don't have a line at the missing points. This is similar to creating an [x,y] pair at each point and specifying NULL, but in some cases creating an [x,y] pair for all missing points isn't practical.

I created a polar spider graph and I would like to know if it is possible to set scale (min and max) for each categories.
I would like change the min and the max, ie for a category A I have values from 0 to 200 and for another category B from 0 to 1. Currently, category B, I do not see very well because the scale is 0 to 200.
22 votesThis is implemented now as a polar parallel coordinates chart, will be available as of next maintenance release: http://jsfiddle.net/highcharts/dxq8hrd5/
