Google-style Pie Chart Labels
Sometimes the pie chart labels cannot be displayed, or are difficult to understand when the pie pieces are thin. Google's chart API (http://code.google.com/apis/chart/docs/gallery/pie_charts.html) places the labels outside of the chart with lines denoting pie pieces.

Custom positions for tooltips
It would be nice to be able to position tooltips however we want to, instead of always having the tooltip to the left of the markers.
I have already written the code and created a pull request for the feature on GitHub: https://github.com/highslide-software/highcharts.com/pull/243

Allow chart option toggling
Would be great if you could change/toggle certain chart options (for example in response to a user zooming or clicking a checkbox)
For example, I'd like to have this as my zoom selection code:
events: {
selection: function(event) {
if (event.xAxis) {
if ([marker condition]) {
this.options.plotOptions.series.marker.enabled = true;
}
else
this.options.plotOptions.series.marker.enabled = false;
} else {
this.options.plotOptions.series.marker.enabled = false;
}
}
}But currently, setting the enabled flag does nothing.
Some useful options to toggle would be:
chart.options.tooltip.enabled = false;
chart.options.plotOptions.series.marker.enabled = false;
chart.options.plotOptions.series.shadow = false;
chart.options.zoomType = '';I'm sure there are others too.

datalabel inside column option
Option to position datalabels inside the column (or bar in bar charts).
Someting like this http://jsfiddle.net/kzoon/WaACH/, but without having to set stacking to 'normal'.An additional option to anchor the label top, middle or bottom would be very useful.

Highstock navigator should inherit color from baseSeries
By default, the navigator series's color is always blue, as documented here: http://www.highcharts.com/stock/ref/#navigator--series
It seems natural to me that the color of the navigator series should be the color of the baseSeries that is being shown in the navigator.

add Events to rangeSelector
add events to the rangeSelector to give us the ability to dynamically load data if it is not pre-loaded.
I am new to HighStock and looking for a way to load data when a button on the rangeSelector is clicked.
So if i load a months worth of data at startup and my rangeselector has these YTD and 5y buttons, they are currently of no use to me unless i load 5years data at startup.19 votesImplemented `click` event, see: https://api.highcharts.com/highstock/rangeSelector.buttons.events

x-axis label getting overlapped by default
When we have more categories in
x-axis, they are getting overlap with one another and it's looks like a
dark black marks in x-axis. I could not read the categories and chart looks
very bad. Please look the below example for your reference.I know there is something todo with highcharts by using staggerlines ,..etc
But it would be great, if highcharts automatically finds the label size and
rotate the labels. Even if you skip some of the intermediate labels that is
also looks good to me. Because somehow i would like to represent my chart
is looking good.…19 votesImplemented in v4.1.0+

High and low plot lines
allow for a low and high plot line on a graph so if the line goes above or below these plot lines the colour of the graph line changes. A nice instant way of visualising if a graph goes beyond certain 'ideal' limits.

Editor plugin for privately hosted charts
Take the editor interface from the cloud product and provide it as an optional library for privately hosted charts. Therefore, we can allow our users to dynamically format a chart (according to what we want to allow) with hooks so that we can privately save their changes.
For example, I want to allow users to customize the series color, marker size, style, etc. I can build my own web interface to collect/store these settings, but it would be great if there was a canned one that I can just plug in and capture the changes.

Scrollable heatmap
When we generate heatmap with large amount of data, the cells become too small and data labels don't appear for all of the cells.
Can we have a provision to set the minimum height and width of the cells and make the heatmap scrollable?

Split the chart when the values are very large & very small
When the chart has a lot of small values and a few very large values, we can't see the trend of the small values clearly.
Often ,we solve these kind of problems by splitting the charts.
refer to: http://highslide.com/forum/viewtopic.php?f=9&t=1338715 votesThis can be achieved with axis breaks (http://api.highcharts.com/highcharts/yAxis.breaks) introduced in 4.1.0
