Thanks for posting!
The first step would be to profile the non-boosted code to get the best performance out of it in each case.
Can you show us a live demo of your problematic chart?

We have pie charts and variable radius pie charts in Highcharts. What specifically are you looking for?
An error occurred while saving the comment I see, it would be like a variable radius pie with support for zThreshold and negative values, which is currently not supported. See https://www.highcharts.com/docs/chart-and-series-types/variable-radius-pie-chart

Added a study for integration with Handsontable, a third party grid component: https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/studies/summary-table-handsontable/2017-09-11
The data table is now a feature of the data-export module. See http://jsfiddle.net/highcharts/VEs7z/3/. Notice how it updates as the chart is updated (for example by showing/hiding series).
2014Here’s a proof of concept of how you can draw a table programmatically: http://jsfiddle.net/highcharts/VEs7z/
An error occurred while saving the comment I added a study for integration with Handsontable, see https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/studies/summary-table-handsontable/. It can also be extended to other third party grid components. It gives you sorting and formatting etc from the third party libraries.
An error occurred while saving the comment Yes, like this: http://jsfiddle.net/highcharts/VEs7z/3/. Or did you have something else in mind?

To hide the chart itself you could always use display: none: http://jsfiddle.net/highcharts/VEs7z/4/ -

An error occurred while saving the comment Thanks for writing!
I'm not sure what you mean by this... "avoid filtering series on the main chart". Can you elaborate, or provide sketches?

Multiple legends feature is currently planned and the implementation has already started.

An error occurred while saving the comment Thank you for your idea! An obvious place to put it would be under the time options structure. https://api.highcharts.com/highcharts/time

An error occurred while saving the comment Thank you for the idea! It can probably be achieved today by analyzing the data up front and setting an appropriate break to the axis options.

An error occurred while saving the comment Not sure what you mean by "chartbook format" - do you mean the dashboard/table layout? If so, it can easily be done by adding mulitple Highcharts charts to any HTML layout.

An error occurred while saving the comment I am not sure I understand what you mean. Consider http://jsfiddle.net/p49ob603/. When you resize that chart (by dragging the splitter in the middle of jsFiddle), the chart resizes, but the text size is constant at its given pixel value.
Do you mean it should be fixed relative to the chart size? Maybe you want to use a relative font size unit? http://jsfiddle.net/yjrzdpn4/

An error occurred while saving the comment Ok, takk for info! Eg er fortsatt ikkje sikker på om det trengst ein option her - for eksempel kan du reversere colors-arrayen ved å gjere colors.reverse() i options-settet ditt.
An error occurred while saving the comment I can only advice you on how Highmaps works, not your UI, but I can see two possible ways of dealing with this for you:
1. Apply the color set dynamically based on how many data classes there are. See http://jsfiddle.net/highcharts/vs9twuLb/ for a proof of concept.
2. Set the colors directly on the data classes: http://jsfiddle.net/highcharts/vs9twuLb/1/
An error occurred while saving the comment I'm not sure what you mean by reversing the selected colorscheme - are you using some kind of GUI on top of Highmaps? Can we see a demo?
Also, for dataclasses, this is how they currently work. If you have two data classes, the chart uses either one or the other color, with no interpolation in between. A demo of what you're trying to achieve would be nice her too.

You can add this to the title dynamically: http://jsfiddle.net/highcharts/h24v71vs/

An error occurred while saving the comment Using separate X axes looks promising. Also by setting the colorByPoint option to false you get one color per series: http://jsfiddle.net/highcharts/znm6f89r/120/
I am not sure how or whether we can align the font sizes between series - my colleague will come back to you about that.

I 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/
An error occurred while saving the comment It's hard to say without seeing your actual code - what I can say is that the point configurations must be objects, then you set that marker configuration on the last of the objects.
An error occurred while saving the comment Thanks for using Highcharts!
> 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.
Does this mean we could solve your case by adding an option for when to remove the markers? Currently they are removed when the closest distance between two points is less than twice the marker radius, i.e. before markers start overlapping. We could easily add an option to increase the threshold. Then if we add a single marker in the cases when they are auto-removed, it would meet your requirement?

New experimantal implementation for Highcharts 4.1 is available at http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/studies/alignthresholds/.
This implementation looks a the threshold on the primary axis (the one first defined), and aligns the threshold of any following axis to that of the primary axis.
An error occurred while saving the comment Thanks for using Highcharts! You still need the plugin for this. Do you have a case where it's not working as expected?
An error occurred while saving the comment Thanks for using Highcharts! You still need the plugin for this. Do you have a case where it's not working as expected?
An error occurred while saving the comment It's not included in Highcharts yet. There are still an issue with how to handle cases when one of the axes' threshold is not in the scale: http://jsfiddle.net/highcharts/gkf9o1vh/.
An error occurred while saving the comment An error occurred while saving the comment An error occurred while saving the comment Bar series per se don't seem to pose a problem: http://jsfiddle.net/highcharts/v44tf7zy/.
Also, I have fixed the "Maximum call stack size exceeded" error.
@Genís Días this also fixes your case: https://jsfiddle.net/highcharts/8dbfhhkp/3/
An error occurred while saving the comment Yes, it looks that way from the jsFiddle demo.
An error occurred while saving the comment @Ronny It will not work with fixed tick positions, because we need to be able to modify the ticks in order to align the axes. Currently it only runs on the second axis. In order to make it run both ways, we need to do some restructuring and make the whole logic recursive, because when the first axis is handled, we don't know the extremes of the second one.
An error occurred while saving the comment @Lukasz Currently you can't set both, as the alignThreshold plugin overwrites the alignTicks setting. But in general, if you use a smaller tickPixelInterval, the alignment gets better because it is easier to find an axis resolution that fits both data sets: http://jsfiddle.net/highcharts/y6pbqk6q/2/
An error occurred while saving the comment It's still not perfect, as it disregards the tickPixelInterval setting.
For your solution about setting min and max explicitly. The docs explains why Highcharts adds padding to your setting: http://api.highcharts.com/highcharts#yAxis.min
An error occurred while saving the comment @Luis Miguel: You need to supply a threshold. Lines don't have a threshold by default. http://jsfiddle.net/highcharts/jrXQe/5/
An error occurred while saving the comment The difference is that line series don't have a threshold by default, so you need to threshold: 0 on the line series. I've fixed this in the plugin so when no threshold is given, 0 is assumed.
An error occurred while saving the comment We appreciate the many votes - I'm afraid the train has left for 3.0, and we will have some catching up to do now before adding new features.

Black Label kindly shared their grouped X-axis plugin: https://github.com/blacklabel/grouped_categories
An error occurred while saving the comment That would be a bit like the standard, grouped columns, right? Or do you mean something different? https://www.highcharts.com/demo/column-basic
An error occurred while saving the comment Yes the devs at Black Label are probably happy for that. And you should post the issue at https://github.com/blacklabel/grouped_categories/issues so it is registered.
An error occurred while saving the comment We have sent a pull request for this issue, see https://github.com/blacklabel/grouped_categories/pull/13. We will ask the owners to pull or to give us collaboration rights.

An error occurred while saving the comment It looks pretty similar to me, see http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/stock/xaxis/crosshair-label/
Do you mean that the entire side of the Y axis label should be an arrow?

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
An error occurred while saving the comment Thanks Martin!
An error occurred while saving the comment Hi Martin,
My coworker added a different approach, that uses the tooltip.formatter to look for nearby points. It would probably work better for your case. See oysteinmoseng's comment on https://github.com/highcharts/highcharts/issues/647.
An error occurred while saving the comment Hi Peter,
Currently we don't have plans to do this internally. Is there any specific reason you don't want to do it like in the demo below?An error occurred while saving the comment It's not currently supported out of the box, but one way to do it would be to write your own interpolation function and add an interpolated line. I set up a demo here: http://jsfiddle.net/highcharts/F4e2Y/

An error occurred while saving the comment I'm not sure what you mean... Can you elaborate with an example?
Here's an empty series. No line is shown: http://jsfiddle.net/vqq6rrtr/
An empty chart will render the chart title, credits and stuff that is not related to the data. If that is not desired, you should defer creation of the chart until the data is ready.

Here’s a plugin that works with columns as well: http://jsfiddle.net/highcharts/Ha3Wr/
It works by setting the opacity on the group element. I don’t expect it to work in legacy IE though.
An error occurred while saving the comment @Anonymous The plugin works for all-line charts too: http://jsfiddle.net/Ha3Wr/57/
An error occurred while saving the comment @Ke Zhao I updated the plugin to work also with pies. Please reload the jsFiddle now.

Related to this idea, I found a major performance issue with data labels. The default settings for sankey made Highcharts produce empty data labels for the links, resulting in wasted performance on the anti-collision logic.
This has been fixed in https://github.com/highcharts/highcharts/commit/647d870ef152ad694bbbe89a7b2d0603a150e76c and will be part of the next maintenance release.
Until then, the workaround is to set dataLabels.formatter to a no-op function (return undefined). See it live at http://jsfiddle.net/a6Lgyn2q/ .
