Enable second row of boxes in timeline
In the timeline graph, if there is sufficient height in the graph, it would be great if the points that are hidden because overlap: false is set, that if there was space to render "two" (or more) rows of boxes (with longer connecting dots) that those boxes were rendered above/below the original boxes.

dragging the dependencies on run-time by user like nodes can be dragged at run-time by user in interactive-gantt
Steps to replicate –
Click on the following URL -https://www.highcharts.com/gantt/demo/interactive-gantt
Click on “Edit in JSFiddle”.
Try dragging “prototype” or any other node.
Unlike nodes which can be dragged by user at run-time, (dependencies) dependency arrows cannot be dragged by user at run-time.4 votesThanks for the idea, it makes sense to be able to drag the dependencies. We’ll discuss this in house.

Patterns in venn diagram
How shall we add patterns and visibility of series in venn diagram? So that can represent the intersected data in patterns and can also disable the unwanted circle through aps by controlling visibility from aps. If you have any kind of solution kindly reply as early as possible.

Allow multiple targets in bullet chart
Please add multiple targets for bullet charts. We have to need to show multiple targets; eg soft targets, hard targets, benchmark etc.
Ideally, each target would be a different colour and there would be a hover-over legend

Gantt + Boost
Gantt chart is really cool but performance limits you to maybe 10-20 rows. We need to support over 1000, with interaction. Animation is not important. Currently the boost module doesn't work with gantt, but if it did it would be truly awesome.
28 votesThanks for writing! The Boost module deals with the data points, in this case it would rendering the rectangles for the tasks.
I don’t think enabling Boost for Gantt would make a very big difference. Rendering 1000 rectangles in SVG should’t be a problem in the first place. I suspect the performance bottleneck is something else, like the grid axis or something.
Can you share a demo of your problematic chart, where we can do some profiling?

Define two font colors for datalabels depending on inside or not
In a bar chart I found no way to define if datalabel is inside or outside of the bar. Highcharts computes this depending if the text fits inside or not.
When you have a white background and a colored bar, and you want to have the complementary color for the text depending on inside or outside of bar there is no way to find out which color to set, because highcharts positions the text dynamically. e.g. on changing browser size, the position can swap from and to inside or outside of the bar.
Sample: some labels are inside and some…

Make accessibility mode the default
In the existing docs, it states:
We recommend to always include the accessibility module, unless there is an explicit reason not to do so. Including this module will make your charts compatible with assistive technologies used by people with disabilities, and also improve the usability of your charts, helping you reach a broader audience. Including the Accessibility module will also help with SEO by making your charts more visible to web crawlers.
I seriously commend you for providing this support, but is there any reason not to make this the default and opt-out instead of opt-in?

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:

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

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.
