manually set the column width
some times the chart will only show a single column in a x axis. If the layout size is large then the column looks huge! Would it be possible to control the width of the column?

Additional data for point
It would be nice to be able to add an array to a point, call it 'user' or 'data' and make it available to the tooltip formatter.
This way, extra information can be stored in the point and rendered in the tooltip.
E.g. I have a graph that shows how many people are listening to my radio station over time, it would be nice to add the title of the song that was playing to the tooltip.3 votesYou can! The config object is available from the tooltip formatter as point.opoints. See http://jsfiddle.net/Z2GRH/.

Zoom buttons should retain "on" state for as long as possible
In Highstock, when you press one of the Zoom buttons, the button visually enters an "on" state. If you then view a different part of the graph, either by dragging the graph or using the navigation scroll bar, the button turns "off". Why? The time window is still exactly the same, so the button should stay "on". The button should stay "on" until the size of the window changes.

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.

Normalize series on zoom
For stock charts, it is often useful to show two or more stocks or indexes normalized so that the Y axis shows a stock price of the primary series but the series are scaled so that they represent % gain or loss. For example, in a two month time period, APPL (series 1) may start at 376.00 and gain 10% to end at 413. In the same time period, the S+P might start at 1300 and gain 10% to end at 1430. Without normalizing, it would appear that the S+P had a much better month when displayed on a line…

Extend the axis 'max' property to act like css min-height rather than a hard ceiling
This would allow the (y) axis to be set to, say, 1-100 but if a value > 100 came along it would resize the max property to fit rather than simply truncating the points.
This is not the same as leaving max unset because that will show a value of 2 at the top of the axis if that's the largest data point. I don't want the axis to scale below max, just above it.40 votesThis is implemented now and will be released with version 5.0.1. The new options are called softMin and softMax.

Add Scaling Methods (HighStock)
It would be great if we could call a method on an already created chart to scale it to a certain interval. For instance, I would like to create a link somewhere on my page that when clicked would change the X-Axis scale on my chart. It would be nearly the same as the provided buttons, but I could put them anywhere on my page I want.

Allow Disabling Series by Default
I want to have the ability to disable a data series by default, so that when you click on its legend item it shows, instead of hides. This will give me the ability to put many series on one graph, only show the core ones, while allowing users to show additional series if they need.

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
