Hide tooltips when dragging on a chart to perform a zoom
When dragging on a chart to perform a zoom, hide any showing tooltips as they cover up the dragged area and make it difficult to see what area you are selecting for your zoom.

Animate chart when showing fewer data points to be consistent
Currently if you add more data points and correspondingly increase the categories you get an animated transition. This does not happen however when you reduce the data points and categories. http://jsfiddle.net/mEFv7/1/
To be consistent, can we please animate both ways.

modify NumberFormat/DateFormat globally
As far as I've understand the src of the highcharts, there is no way to change the internal functions defined inside the closure, unless you edit the source file.
but the ability to alter NumberFormat/DateFormat functions (e.g. change number digits from english to arabic everywhere in the chart) is very needed for i18n.
is there any plan for supporting this?3 votes -
Master detail chart with irregular interval
I am not sure if this is already there. I just want to do a master detail chart where time can be at irregular interval and nothing is hard coded in the chart. I got a array of (Epoch time, value) pairs and everything drives from it. Any suggestions ?

get the mouse position on the chart
as you can see at http://www.flotcharts.org/flot/examples/interacting/index.html
(hover your mouse on the graph and look at bottom: show mouse position)
you can have mouse coordinates on the graph,today in highcharts i can only have the mouse coordinates on points,
but i want to have a feature that can allow to get the coordinates of the mouse independently of the drawed points.
it would be great!

Add broken line segments for null values
If the 'y' value of a point is null for a line type of graph, then option should be available to either automatically switch to a dashed line or not to display the line entirely till 'y' gets set to non-null value

Set <svg> shape rendering property
http://www.w3.org/TR/SVG/painting.html#ShapeRenderingProperty
Allow setting of shape-rendering attribute in order to enable speed optimising.
Code modification example:
SVGRenderer.prototype = {
/**
* Initialize the SVGRenderer
* @param {Object} container
* @param {Number} width
* @param {Number} height
*/
init: function(container, width, height) {
var box = doc.createElementNS('http://www.w3.org/2000/svg', 'svg'),
loc = location;
attr(box, {
width: width,
height: height,
'shape-rendering': 'crispEdges', //suggest to add this by config7 votesYou can set it using CSS:
svg.highcharts-root {
shape-rendering: optimizeSpeed;
}See http://jsfiddle.net/highcharts/qkdynr7s/. You can see from the ugly, jagged line that it works.

Add delayed draw of legend (after graph animation is complete) please.....
As of now the legend is displayed immediately (while the graph is still being drawn/anuimated). The idea is to delay drawing of the legend until the graph has completed animatino...

Add Print and Export events handler
It'd be useful to have access to some more events, specifically I was thinking about 4 new events which could be captured and managed by dedicated handlers: onStartPrint, onFinishPrint, onStartExport and onFinishExport
The first two are related to the act of printing the chart via the print button, the other two are related to chart exporting.

Show value on top of plotline or allow multiple labels on a plotline
Plotlines are excellent to point out interesting Things in the chart. With large datasets it can be a good thing to be able to have an additional label for the exact value of that plotline

Panes should have individual colors
Currently multiple panes could have individual colors on each alternate grid row via setting "alternateGridColor". Well that's the half! To see on
http://jsfiddle.net/6AxvV/1/A new option "GridColor" should set the color of all grid rows of a pane. The option "alternateGridColor" shall remain unaffected.
