I would like to have an approximation function in which we can access all the information from the points instead of just the y values. This allows me to not only decide how to group but also an ability to capture information from all the points into the grouped point.

If I tend to display huge volume of data, chart GUI is not stretching to accomodate all contents, instead it reduces their dimensions to incorporate them within given area. This makes chart unreadable, also leads to overlapping of data during display. It will be great if chart length grows horizontally on more data and provides a scroll bar

Geo chart is really cool, dont you think. http://googlevisualr.herokuapp.com/examples/interactive/geo_chart

Hi

I would like to suggest a small improvement concerning exporting. At the moment, user that wants to save a highchart has to click on a download icon and choose an option from a dropdown.
A small but great improvement would be to do the same, just by right-clicking on a chart.

You just right click on a chart -> save as -> desired format and voila!
I am not sure if sucha feature is possible to implement, but it would be neat to have this! :)

For the slices of a pie chart, allow the user to specify border attributes differently for inside, outside and separator borders. I would like to specify no border for the outside and inside of a donut chart, but still have borders between the slices.

Would like the ability to keep the tooltip shown after the users mouse has left the chart. Pretty easy to add.

Add option tooltip.sticky

Current 3.2.0.
Line: 1613. Add sticky: false.
Line: 8672. Add && !chart.options.tooltip.sticky.
Line: 8618. Wrap with if statement (!chart.options.tooltip.sticky).

Auto-Plotlines for aggregate functions like Min, AVG and Max based on the series values.

This would be accessible via the series or plotline objects and would draw the lines automatically (ui default properties for each plotline defined as well and not null) for the aggregates on the values of the series.

It would be most useful to restore the "target" option in the "credits" configuration so that when the user clicks on the credit text (usually in the lower right angle of the graph), the link can be opened in a new page instead of the current one.

It should be possible to sum up negative and positive values in the same stack (like excel does for area charts by default).

Currently positive and negative values are stacked seperately above and below the x-axis. To keep BC and keep the old behaviour as well a new stacking mode should be added IMHO.

It would be great to control line breaks completely using non-breaking spaces (&nbsp;), <br> tags and soft hyphens (&shy;).

There is the ability to print a chart and to create a pdf of it, would be great to have email option to email a pdf of chart to someone

highcharts is a litter larger for mobile,should we have a mobile edition? highcharts should not rely on other frameworks as well,such as jquery.

Events triggered when a user clicks/hovers/etc a category label (xAxis labels).

I would use this to provide more in depth information about the label clicked. For instance, charting years in xAxis, user clicks 2012, should bring up a menu with additional options for that year

Provide some way of including an image in an axis label. For example, I may want to prefix the axis labels with an icon.

I've tried including HTML in the axis label and using axis.labels.formatter to add image HTML into the label. Neither worked. I've seen reference to using renderer for doing this, but I haven't been able to find an example.

In highstock.js, we don't have postion to place the range selector. Why don't you give the options for placing the range selector(like top, bottom, vertical, horizontal...........)

Instead of having Treemap as groups of rectangles, we can have it as group of circles.

Something like this:

Hope you can do it :)

if the list of columns are to big to display, I would like a way to paginate them and show the columns in groups of 10, 20, etc.

The user would click a given category name, for instance, on a list, and the heatmap would highlight the row/column that corresponds to that category. This would allow for users to look for columns/rows if interest in a faster way, especially when dealing with big datasets.
