Feature in stacked column chart that allows negative values. Positive values should be over the x axis and negative values should be underneath.18 votes

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.16 votes
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?
Details of the issue which can be solved with the above feature can be found here:
Scrollable heatmap is implemented with v4.2.6, see http://www.highcharts.com/news/224-scrollbars-for-any-axis.
How to create a column chart that contains multiple bar and it can be drilled down which it has multiple bar too?16 votes
Drilldown from multiple series into multiple series is supported.
The relevant API option is `allowPointDrilldown`:
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.16 votes
This was completed with series.zones (http://api.highcharts.com/highcharts/plotOptions.series.zones), which was introduced in 4.1.0
1. I'm going to display three data of temperature, wind direction and wind speed in each cell.
2. Temperature color is limited to 4 types in total.
2. The direction of the arrow is limited to 16 kinds in total. (0, 22.5, 45, ... 337.5)
3. Arrow lengths are limited to 10 types in total. (9%, 18%, 27%, ... 90% of diagonal)
Can it be?
If you email to me(firstname.lastname@example.org), I send you some examples about the suggestion.

Drawing a wind barb series on a cartesian plane is possible using the x and y options: http://jsfiddle.net/highcharts/z4m1nrab/
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.

This can be achieved with axis breaks (http://api.highcharts.com/highcharts/yAxis.breaks) introduced in 4.1.0
tooltipInterval is firing every 32ms regardless of the whether or not mouse is over the Chart.
The setInterval should only be created on mouseenter and cleared on mouseleave.14 votes
It is fixed in the development branch
annotate plot bands.
Ways I can think to do this are:
- place text aligned within the plot band (centered, or on the line)
- create a axis like object with extruding labels that connect to each plot band
Added in version 2.1
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 chart. In reality, they both gained 10%, which is what we are attempting to compare. Additionally, if we were to zoom into the last week of the month, the chart should be displayed so that the first point in each series starts at the same place on the Y axis so that we are comparing loss/gain % within the zoomed time period.

As of today, Highcharts library requires you to mouse over a specific point to show the tooltip. It should also be possible to display the tooltip no matter where the mouse is on the chart. This solution can be found on different Google charts as well as http://www.campaignmonitor.com.12 votes
Added tooltip.shared option in version 2.1
example : if the point.close is smaller than point.open, the color is red..vice versa11 votes
Implemented in the development branch, it will be generally available from the next maintenance version. See http://jsfiddle.net/highcharts/tLpVz/ for demo.
There are 3 reasons for wanting this:
1 To enable users to add/remove points using the legend
2 Data labels don't fit in the smaller data points. If you have several smaller data points the labels either overlap or get suppressed
3 When a treemap and other chart types are presented side by side, they should look the same as much as possible. Having a legend on all chart types does just that.11 votes
Thanks for your suggestion! I did some refactoring to allow this functionality with more series types than just pie and its derivatives. For example it makes sense for columns with colorByPoint also.
The commit is available at https://github.com/highslide-software/highcharts.com/commit/a20dd76eb207defc1df92efd5a91738835e4f595.
As a keyboard user I would like to be able to activate features which are currently only available to mouse users.
For example I would like to tab to a line plot data point to expose the tooltip balloons. I would also like to be able to use my keyboard to activate the links which are currently mouse click only.10 votes
This is now implemented in the Accessibility module: http://www.highcharts.com/docs/chart-concepts/accessibility
It would be a nice feature (especially for highstock) if we could change the height of a pane (yAxis) by clicking on its horizontal boundary and dragging it (simultaneously changing the height of the adjoining pane)10 votes
Implemented as of Highstock 6.0. See https://api.highcharts.com/highstock/yAxis.resize
have mutli pane charts like eg in financials stock charts you have price, volume, volatiility in 3 separate panes10 votes
