It would be great if the borders around the charts had similar controls to that of CSS where we could edit the border colors and thicknesses individually. My one example is that we need to have only the left border of a chart thick red while the rest of the borders are to remain thin and gray. Here is an example image: http://connect.urnerbarry.com/public/album_photo/1d/09/0914_e1ba.PNG?c=332c
I think it is a little bit too specific to add to the configuration API, but you can simple add this as a small plugin.
Please, add the possibility of specifying the gapSize in seconds (eg gapTime). It will be very-very useful for timeline charts for Highstocks and Highcharts.6 votes
For the records, it would not be seconds specifically, but X values in general.
Here’s a snippet that makes the gapSize apply to absolute X values (meaning milliseconds in our case): http://jsfiddle.net/highcharts/wado3rku/
If we implement this in the core, it should probably be called gapValues or gapSizeAbsolute, but we need to check how it works with an ordinal axis.
data module was a great addition. have been using that pretty much everytime i can covert my data to csv.
but having database module to load data from one table would be just awesome.116 votes
Making backends for data bases is complex, as it covers a wide range of different databases and languages. A project like this would have to start with only a few of the most popular backends. We are currently considering a “connectivity” project that will do some of this.
Currently the navigator is positioned at number 2 point in the axis array if new axis are dynamically added otherwise it is the last element. This makes indexing int the axis array unnecessarily complicated and confusing. I want that the navigator array either be taken out of the xAxis array and have its own array or at least have a consistent position1 vote
Use the xAxis.options.className to filter out the navigator axis.
With Highchart version 3.0, the chart does not get rendered on mobile orientation change. I am not sure if this is available with Hightchart ?4 votes
Highcharts doesn’t do anything internally on orientation change, except it reflows if the window.resize event fires.
You can add your own listeners to orientation change though.
What does the case look like? Is there a problem?
When a border is added to bar/column charts, the border goes X pixels around the bar. This causes the bar to overlap over the axis lines and possibly other bars. See this JSFiddle example:
It would be nice if it could look more like this instead:

For Highmaps, we should have a method to find which map area a point lays within. Useful for building heatmaps.1 vote
Thank you for your request.
Be able to easily get data from PostGIS, import a KML, or a simple MultiLineString.0 votes
Thanks for the feature request.
It’s a good idea, Iit would require that we either are able to send images directly from the browser memory to the social media APIs, or that the export server passes the images to the APIs.
Add directional arrows to your map line10 votes
See http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/samples/highcharts/studies/direction-arrows/ for a proof of concept.
This would allow SVG paths to be shorter in many cases, which would reduce data size, and make the page load faster.
For example, SVG path for a rectangle could be
"M400 400L432 400 432 428 400 428Z"

Thank you for your suggestion.
add the ability to insert a custom class to data points matching specific criteria. If range is 1-9, if range is 10-19, etc.
If a data point is between X and Y integer, give it "class='low-range'" if a data point is between A and B interger, give it "class='custom-class'", etc.1 vote
Here’s how you can do this currently with a little extension: http://jsfiddle.net/highcharts/tc5b2vbr/
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 plotline1 vote
Thank you for your suggestion.
i cant find any code snippet for using map-parser0 votes
Thank you for your request.
If I've got a sparse dataset (e.g. to save space, duplicate data points are omitted), a line graph still represents the data accurately, however the tooltip only appears over the actual data points.
Would it be possible for the tooltip to interpolate the data at the mouse pointer's position so as to show a value whether there's an actual data point there or not?42 votes
Here’s a little hack to display an invisible, interpolated series above the data series: http://jsfiddle.net/highcharts/F4e2Y/
See alto the associated GitHub issue: https://github.com/highcharts/highcharts/issues/647
I want to do something after the tooltip shows.
And I found the "point hover" event
But when I use the "crosshair" option, it doesn't need to hover the points to trigger the tooltip, anywhere of the chart triggers the tooltip
So now I can only do something when user's mouse hovers the points
I want to do it when the tooltip shows,
So i think it's better to add a "after tooltip show" event in options.
You can use the internal chart.tooltipRefresh event: http://jsfiddle.net/highcharts/Ym4UA/
As mention in the comments for "Fix spline plots" (http://highcharts.uservoice.com/forums/55896-general/suggestions/871839-fix-spline-plots-to-draw-a-better-generalized-line), sometimes the built in spline fit method is not acceptable. It would be great if there were other fit options built in (like D3: https://github.com/mbostock/d3/wiki/SVG-Shapes#path-data-generators) or allow custom algorithm to be plugged in.0 votes
Actually there is such a method, getPointSpline. It computes the line segment from one point to the next. It takes arguments for the whole segment, the point and the index, so you can add the surrounding points to the calculation as well. See http://jsfiddle.net/highcharts/6sQjJ/.
Would love to have linear gauges like this:19 votes
You can create linear gauges from columns or scatter charts with one single data value: http://jsfiddle.net/highcharts/9ybLv5je/.
Now highcharts support setting offset pixel of x axis to specify x axis position,but is not convenient, it is better to support setting offset of x axis with concrete Y scale value rather than pixel value. please see example http://jsfiddle.net/cxARQ/5/ , I want to set position of x axis at 50 of Y axis, but it is hard to set exact position with pixel.9 votes
I would like to be able to choice the position of my axis, for logarithmic chart or not, like this image : http://img15.hostingpics.net/pics/881099axis.png
Indeed, I need to split my chart in 4 part in taking the x-axis and the y-axis in a exactly point.
Have you got a solution or is it possible to take this in the roadmap?
You can position your axis absolutely through the offset option: http://api.highcharts.com/highcharts#xAxis.offset.
Combined with chart.marginLeft, chart.marginRight etc., it provides absolute pixel positioning control.
