scientific notation
It would be nice to have a default formatter for displaying numbers in scientific notation
3 votesHere’s an idea of how to add a format for scientific notation:
http://jsfiddle.net/highcharts/pLy4g2dk/
Alternatively, Number.toExponential can be used inside formatter functions.

Bubble Coloring
We have a requirement to color the bubble depends on the size. Basically, if the value is high, it will have a darker color and for a low value, a lighter color.
3 votesBy borrowing some functionality from color axis, you can compute dynamic colors for the bubbles: http://jsfiddle.net/highcharts/pa9byxym/

Allow column chart rounded corners to display with non-zero y-axis
If you have a chart such as the following: https://s3.postimg.org/juxazrv5f/Screen_Shot_2016_08_19_at_20_19_08.png
And you change that yaxis 0 value to non-zero, i.e. 10, then the following occurs: https://s3.postimg.org/jdop36c8z/Screen_Shot_2016_08_19_at_20_18_27.pngWe urgently need a hack/workaround to once again display the rounded corners. We are using Torsteins rounded-corners plugin to achieve this.

Exportable individual border thickness and colors
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
There is an old idea that is similar but doesn't appear to have any replies other than mine here: http://highcharts.uservoice.com/forums/55896-highcharts-javascript-api/suggestions/4974960-can-we-have-series-border-options-like-left-border
3 votesI think it is a little bit too specific to add to the configuration API, but you can simple add this as a small plugin.

add a method getExtremes() to the Series object
This would allow retrieveal of max and min data for that series. On a multi-series graph the axis extremes are nice, but being able to grab the extemes of each series would allow for more flexabiilty in data display.

Option to export PDF to dataUri string instead of downloading
It would be nice to have an option to export chart (as PDF) to datauri string instead of file.
This can be done now indirectly, by obtaining chart's underlying svg, calling svg2pdf and finally using jsPDF doc.output('datauristring')
[which returns the base64 dataUri] instead of downloading file.Maybe as an option in 'exporting' object?
Or by exposing new method, i.e. Highcharts.exportToUri() ?Or maybe there's some simpler way that I am not aware of?
Thank you.2 votesThank you for your request! By extension, this applies to PNG and JPEG exports in addition to PDF. You can override the Highcharts.downloadURL function to capture the dataURI. See http://jsfiddle.net/highcharts/9my975x4/.

add "after tooltip show" event
I want to do something after the tooltip shows.
And I found the "point hover" eventBut 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.
thanks
2 votesYou can use the internal chart.tooltipRefresh event: http://jsfiddle.net/highcharts/Ym4UA/

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.

Provide the option to let piecharts show the larger segments on top
Reading a pie chart is like reading a clock. It's most effective to place the largest segment at 12 o'clock (as it does now). The best way to order the rest of the segments is to place the second biggest slice at 12 o'clock on the left; the rest would follow counterclockwise.
1 voteThanks for your suggestion. For now, you can just sort your data by value before adding it to the chart.

Show value on top of plotline or allow multiple labels on a plotline
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 plotline

Add support for relative (lowercase) SVG operators in path
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 400h32v28h-32Z"
instead of
"M400 400L432 400 432 428 400 428Z"

Draw border for bar so that it doesn't increase width of bar
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:
http://jsfiddle.net/aaewong/6kmu11md/5/It would be nice if it could look more like this instead:

navigator axis position in xAxis array should always be at the end position or removed
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 position
1 voteUse the xAxis.options.className to filter out the navigator axis.

highchart - chart should be overflow = auto
Can we have any highchart functionality/feature that dashboard can automatically adjust width(HScroll bar) & height(VScroll bar) ?
Like chart should be overflow = auto (as per data)
