moment is DOA, please replace dependencies
moment.js and moment-timezone.ts are obsolete. Please remove dependencies on them. In fact, don't add dependencies, provide a callback for the needed functionality so we can choose between luxon and spacetime.

waterfall: non-numeric total date xAxis label
The totals column on a waterfall with a date is always placed on the timeline somewhere. The totals isn't actually a part of the date timeline, it's an aggregated value and should be able to be marked as such.
Basic ask is for an additional tick that is customizable that represents the placement of the placement of the connected totals column.
Problem described more fully here:

https://highcharts.uservoice.com/forums/55896-highcharts-javascript-api/suggestions/3517780-show-hide-one-or-more-bars-in-bar-column-chartThere are a few suggestions of this here in UserVoice, but those seem too scenario-specific and I thought I'd just make a compilation of all of them here.
Even something as simple as just providing an additional object for each category that contains what points it has from each series.

Boost Module for Sankey Chart
The boost module would be beneficial for large dataset when using the sankey chart. We are experiencing a severe degradation in performance with large datasets on this chart type
1 voteThanks 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?

Pie chart with negative and positive values
Hello, we are your customer and urgently need Pie chart with negative and positive values
1 voteThanks for requesting! We’re considering this as a feature for the variable radius pie chart, where it would fit in by applying a zThreshold so that it could visualize negative Z values.
In the meantime, you can hack it by adding two series to a pie chart with different radius: http://jsfiddle.net/highcharts/2g8u7vq1/

Mixing categories and subtasks in HighCharts Gantt?
Hello,
As I tried explaining here : https://stackoverflow.com/questions/54947746/mix-categories-and-subtasks-in-highcharts-gantt
I was wondering if, in Gantt, it was possible to use parent/subtask (folding and unfolding) while also having multiple tasks on a same "line" (mixing "Interactive gantt" demo with the "subtasks" one). Apparently it is not and so I'm wondering if this behavior can be expected in the future.
For now, I think I will use css classes (or another way of identifying the parents/children) to add a bold + folding icon to parents, and to .hide() the depending yAxis when clicked (that means having an event on the label, but I'm…

Resize columns and drag&drop feature in the gantt charts table
In most gantt charts, the ability to resize and drag in addition to the chart for the gantt charts table has also been implemented.
This means we can change the size of the table columns

Support for non-numerical y-axis object array specification
Some charts, such as heatmaps, frequently have categorical x and y axis values. Converting categories to numerical indices adds extra code and possibility for error. X-axis categorical values can be specified within an object array using the "name" field. I suggest a similar field ("yname") to specify y values by name, rather than index.

HighStock.js: add parameter to chart.redraw(numberOfPointFromTheEnd) API method
Hello,
I develop application related to stock market. I have a case when there are three charts displayed (area, candlestick, column) that needs to be updated when stock price is changed but not more than one time per 2 seconds. Each chart type (area, candlestick, column) can contain 15000 of points. Here is live demo: https://jsfiddle.net/ogorobets/8gb54cyh/5/. As you can see there application hangs out because of big load.
My proposition is to have "numberOfPointFromTheEnd" parameter in chart.redraw() API method to redraw only last few points but not whole chart. This way redrawing chart can take much less time.

Add categories
Hi
There are a categories in the chart for several tasks
An example in the link https://www.highcharts.com/gantt/demo/interactive-gantt is to add a task that is not what we want.
Is it possible to add and edit categories?
For example, there's a button to get a text and add to the list of categories

Add an option to the navigator to behave like the range selector
I would like to have an option in the navigator that avoid filtering the series on the main chart. This option will allow the navigator to behave as the range selector.
At this moment, the navigator can be easily customized with the JS API and CSS; my goal is to style the navigator to be a horizontal bar with handles that can be used as the range selector.

Native option to zoom and center highmaps on nonempty regions

https://gyazo.com/35fd0d74d3e773f694790c5fc0c95eceand now i can show only usefull part of highmap, by default:
https://gyazo.com/d7ca32d8ce8b1535bddd331a997c67b8{code}
const points = this.chart.series[0];let minX = Number.MAX_SAFE_INTEGER, maxX = Number.MIN_SAFE_INTEGER, minY = Number.MAX_SAFE_INTEGER, maxY = Number.MIN_SAFE_INTEGER; if (!points) return; this.chart.series[0] .getValidPoints() .forEach(item => { if (item['_minX'] && item['_maxX'] && item['_minY'] && item['_maxY']) { minX = Math.min(minX, item['_minX']); maxX = Math.max(maxX, item['_maxX']); minY = Math.min(minY, item['_minY']); maxY = Math.max(maxY, item['_maxY']); } }); this.chart.series[0].xAxis.setExtremes(minX, maxX, true); this.chart.series[0].yAxis.setExtremes(minY, maxY, true); this.chart.redraw();{code}

Support custom fonts in graph exports
When exporting graphs to any format, if you are using a custom font that is not installed on the user's computer (even if you are using the CSS @font declaration to include it for your site), the font will not be used on the exported chart.
Example:
http://jsfiddle.net/n2rcogxa/You should be able to solve the issue by embedding the base64-encoded font in the SVG document prior to converting from SVG to whatever the desired format is (PNG, JPG, PDF, etc).
Example:
http://jsfiddle.net/moyf3zvb/2/Note you must actually embed the font. Including it as a @font declaration in the SVG document does…

Validate chart options
Chart options strongly depend on chart type and other options. For example, ticks on x/y axis. Depending on what type was chosen (linear, logarithmic, datetime or category), ticks are configured differently.
And I really suffer when I read docs and don't clearly understand which properties work with others, and which are useless together.
I suggest you to update docs, or implement chart options validation, or even provide us some external service to check, if given options are valid. In ideal world, if options are not valid, it would say why and maybe suggest something.
3 votesThanks for requesting! This kind of validation could be added to the debug module.
We do try to add information about conflicting options in the API docs however. Are there any specific cases that we failed to mention?

Static library support
Hello,
First of all thanks for great library. In our company we are using licensed version and we need static library support for cocoapods.
Using "usemodularheaders!" in Podfile causes to have pods as a single static library in the project which results in smaller app size and reduced initial load time for the app. We discussed the support in github : https://github.com/highcharts/highcharts-ios/issues/150
We will really appreciate if this is supported.
King Regards
