linechart symbol markers at the end of each line
At SSB we have a lot of auto generated charts, and need symbol markers on charts to fulfill accessibility requirements, but on a lot of our linecharts the point density is so great that the chart becomes unreadable, but not dense enough for the "null" option to kick in and remove the markers.
Therefor, what we need is that marker symbols appear at the end of each line, while also appearing at the corresponding legend.
(We tried a solution that was posted in another feature request, but found no way to implement it with auto generated charts and also it…
3 votesI have implemented a new option, enabledThreshold. Now we can explicitly add a marker to the last data point to achieve the required effect: http://jsfiddle.net/highcharts/sj167xkm/

Capture drill to node event in treemap and sunburst
Currently (v6.1.0) Highcharts options doesn't allow to capture drill to node event in treemap and sunburst.
I would be useful to add
drillDownToNodeanddrillUpToNodeevents that will work analogically todrilldownanddrillupevents.Here's a link to the topic that highlighted this problem: https://stackoverflow.com/questions/50279912/dynamically-changing-subtitles-at-various-drilldowns-in-treemap-in-highcharts

Add a mouseOver delay
I would like to be able to set a delay for mouseOver event firing. Currently, the mouseOver event fires immediately resulting in multiple firings as the cursor is dragged across a chart. For mouseOver event functions that require some time to process the results can look choppy and confusing. This would be especially nice for heatmaps where central points cannot be reached without mousing over other points.

3D charts with z-axis having dynamic depth
Currently in 3D charts, if you have a 'column' chart the z depth is not dynamic, it stays the same default of 100 and never updates with more/less data. This is very different from the how all 2D charts work with the data filling the frame, and how 3D scatter works with the data filling the box. I think it would be more consistent/intuitive if the 3D column chart had this feature built into it, and and force the user to override the dynamic sizing if they don't want it
Here is an example of what I am talking about: …

Drill down charts that can handle more than one series at the drill down level
A top level graph to be a bar (actual values) and line (expected
values) graph for various categories. Then when you drill down into a
category, a bar (actual values) and line graph (expected) again
showing data over time for that category.16 votes -
Avoiding series overlap
Let's say I have a chart similar to http://jsfiddle.net/k7n8cf8m/
There are two lines with almost same data.I've got a question if is there a possibility, to present those lines joined together, one above, second right below (without padding or anything, just 2 glued together lines). I mean it shouldn't overlap each other, but display like a rainbow instead.
Something like that: http://jsfiddle.net/BlackLabel/3goqaqfj/
But without changing data values.Is there a chance to introduce something like that in near future?
6 votesThis is a bit similar to the minPointLength option – https://api.highcharts.com/highcharts/series.column.minPointLength, which aims to ease readability when points overlap. It also has the same logical problem: If a small offset is added for multiple series or points after each other, eventually the points will be drawn off scale.
Here’s a small plugin I wrote that offsets the series by an optional amount of pixels per the series index: http://jsfiddle.net/highcharts/vgdga7vw/1/. As you see, it doesn’t actually consider if any offset is necessary, plus when you have a lot of series it will be off scale.

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/.

Multiple dimensions on 2D chart
Most people use the 2D charts with 2 variables only. But with the advance in data analytics 2 variables on the same charts are no longer enough. We need to be able to display multi dimension on 2D charts. Few ways to achieve this are:
* Allowing the size of the markers to change to based on a third dimension
* Allowing color of the markers or lines to change based on a 3rd dimension
* Allowing shape of the markers to change based on a third dimension.If we apply all the options above we should be able to…

Auto-Calculated Bar Width
It would be interesting to have the width of the bars adjusted automatically. Something similar like this: https://js.devexpress.com/Demos/WidgetsGallery/Demo/Charts/AutoCalculatedBarWidth/AngularJS/Light/
4 votesThank you for your suggestion, that’s a nice solution to column placement challenges. Alternatively, the column width could be the same, but the position centered inside the category.

Draggable crosshair label
It would be nice to make a crosshair label draggable. So that user can move with the mouse the crosshair label away from the x-axis.
Image: https://imgur.com/a/nlqGhOr can it be another draggable element that will show what crosshair label shows?

Add Philippines' Provinces' Cities and Municipalities
I have tested your drill down map in yur USA example.
But I tried to replace all "us/us" to "ph/ph" in order to use it in my beloved country, but it looks like I cannot drill it even at least to provincial level.I wish you will provide data for that

Accept chart settings and data and return a PNG of the chart
Create a service similar to https://pdfcrowd.com/.
Create an API endpoint that can convert settings into a file format (PNG) that is charged either per conversion or annually.
The API would take our chart settings and chart data, plot the chart on your server side and return to the client a PNG (or other supported file types) of the chart we requested.
4 votesThank you for your suggestion!
Currently, you can use our public export server to do this. It runs at https://export.highcharts.com and accepts parateters as described at https://www.npmjs.com/package/highcharts-export-server.
There is however a limitation of 10 charts a minute. We are considering setting up a commercial service to allow more conversions.

Add grouping in chart legend
Would be good to have grouping in legend so user can play with group as well as with legend item by clicking on it to show/hide items.
Click on group should work as click on each item in the group.Could look like in this picture: http://forum.highcharts.com/resources/image/4056

Optional function for yAxis to determine the column height based on its value
Though there is plotOptions.column.minPointLength property, it doesn't solve the problem completely.
Imagine there are columns which may have 0, 1, ... 1000 as values. These large values cause small values like 1 look like 0, i.e. no column is drawn.
By setting the plotOptions.column.minPointLength property to 3, causes the 0-value columns to be displayed as well.
All I want is to display the non-zero values to indicate to a user that there are some very small values.
