Export should include all visible elements (Plot Lines / Bands)
Export should include all visible elements of the current chart, this should include all post-added elements, like plot lines and bands. Series do appear to be included if added after-the-fact, but plot lines and bands are not.

Add support for Range Select via Shift+Click to match OS Behavior
Currently Ctrl+Click and Shift+Click will multi-select data points. Allowing Shift-Click to support range select behaviour would be more inline with common OS behavior and also allow for rapid selection of multiple data points

Columns for tooltip
It would be nice to be able to specify the number of columns in the tooltip. For instance, I have a chart with 44 line series, 22 each for two different data sets. This makes the tooltip too long for the chart area. If I could specify two columns, it would fit fine, and be easy to read.

add a method getExtremes() to the Series object
This would allow retrieveal of max and min data for that series. On a multi-series graph the axis extremes are nice, but being able to grab the extemes of each series would allow for more flexabiilty in data display.

Column chart: gradient fill per column over height of chart
I'm trying to create a column chart showing advice based on weather data. Values are between 0 and 2. Based on the value the height is determined, and currently a singular color. I'm trying to modify this to have a gradient range for top to bottom of the chart, not as a background. Colors should start at the bottom showing red, showing a gradient to yellow (at value 1) and green (at value 2). However, I want the gradient shown even if the value for the column is say 0.615, which would need to show a gradient past halfway, still…

AMD / jamjs support requested
Hello,
I'm using Highcharts quite extensively. Recently i managed to get this library working with require.js and more specifically with jamjs.
First question : are you guys planning to support AMD loading of your library ?
Personally, to simulate the jamjs/require.js package i use this setup
- copy the content of the highcharts js folder to the root of the highcharts folder, get rig of the examples and other directories.
Add a package.json file with this content
…{ "name": "hightcharts", "version": "2.3.5-jam.1", "description": "Highcharts JS is a JavaScript charting library based on SVG and VML rendering.", "homepage": "http://www.highcharts.com/", "main": "hightcharts.js" "jam":3 votes -

when Negative value intervals are bigger than positive valuesthis time it is hard to see the positive values in chart it appears all at one line
we can Zoom it, but no option to specify the range like 0 to 100 interval 10 for positive and 0 to -1000 interval 100
here is the example

Automatically align data labels (values) when a rotation is set
If a rotation is set for data labels (values), the labels should be automatically centered over the chart elements (e.g. column chart).
It's annoying setting the alignment, the x and the y position for every chart.
There may be an additional option to set a padding between the label and the chart element.3 votes -
Add the Ability To Animate Category Positions
Add a fluid animation to re-order axis categories (which would most likely be used for bar or column charts), see:
http://visualization.geblogs.com/wp-content/viz_includes/jobs/#/years/sector/2011
for an example (click play on the timeline).

Initial fixing for compare
It would be great, if i can compare more than one Series per percent. like this: plotOptions: { series: { compare:'percent' } }
But i would say, compare it at a special point (date) so i can compare three series per percent from 1. april 2012, but the chart go back to 1. january 20003 votes -
radius property can work for custom symbol
Currently, the radius propery only works for the default symbol. If specified a customing image, no matter you set what value in radius, the image keep the original width/height.
The behavior of custom symbol should be like default symbol and can auto-scale according to specified radius3 votes -
Ability to select/ deselect axis items
Currently I am able to show and hide series of data in a chart by clicking the item in the legend.
I want to be able to do this also for items that are on the axis of a chart.
In my example: http://jsfiddle.net/xqzdR/
I want to be able to click for instance 'Trail 234'. This should then hide or rebuild the entire chart without this item in the axis.3 votes -
allow custom renderings of chart objects, e.g. bars in bar graphs
So rendering of a bar would be achieved by way of a callback to the user's own code (possibly)

Waterfall un-connected columns at the right side!

Pass the number of nulls instead of true/false to dataGrouping approximation functions
I would like my chart to sum or average points in dataGrouping but only when the most of the points are non-null. e.g. When more than 90% of the data is non-null, then show the sum/average, otherwise show null.
Currently, the data passed to custom aggregate functions only contains the number of non-null points and whether or not their are any nulls. There is not enough information to judge what percentage of the period of time is missing data. This could be easily improved by just passing an integer instead of a boolean for hasNulls. hasNulls could be 0 (or…
