Automated scale breaks
The implementation of scale breaks when there are large differences between the high and low values of the data being plotted.
A sample can be found in the below link, implemented in the old Dundas Charting tool.
The Highcharts feature yAxis.breaks is useful only when the difference between data points is known or when the data is small. The data is dynamic in our case and can be large and the breaks need to be automatically drawn considering not a single series but with respect to all the series present in the chart.
Thank you.1 vote -
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

Events for annotation and indicator changed
For a StockChart every time the user adds, removes or modifies an annotation or an indicator, either over the annotation-/indicator-popup or by dragging an annotation-control-point directly, an event on the chart instance should be fired, so that you can e.g. automatically save the chart-state every time something has changed.
Maybe something like:
Highcharts.Chart#events:annotationChanged
Highcharts.Chart#events:indicatorChanged1 voteKacper Madej responded
Hi,
Thank you for submitting the idea.
Basic events are already here: on chart level we have addSeries (https://api.highcharts.com/highcharts/chart.events.addSeries) and series remove – implemented, but not a part of documented API (demo: http://jsfiddle.net/BlackLabel/0cosmk2g/) or similar series destroy (the same situation).
For series update you could use series render event (not a part of documented API).
Events for annotation update are not yet implemented.
How to resolve:
Generally, this could be implemented through extending Highcharts. Related functions that create, update and destroy annotations could be wrapped to fire additional events. I’ll try to provide a POC later this week. -
Make axis labels formattable so that they all have the same number of decimal places
I would like to have all axis labels rendered with the same number of decimals. Currently, I can fix the number of decimals using the format string, but when zooming in, more decimals are often necessary.
In statistics, it is a general consensus to have axis labels with the same numebr of decimal places to indicate the precision level, so I suggest Highcharts to support this, too, without reverting to custom code.
Currently, it can apparently only be done using custom event code, see this Highcharts Forum entry:
https://forum.highcharts.com/highcharts-usage/how-to-have-all-yaxis-labels-show-same-number-of-decimals-t40826/Thanks for your consideration!

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/

Duplicate Legend
I think currently high chart support legend at single position, but I would like to display the legend on top as well as on bottom of the chart, because if the chart is bar chart and more values then user need to scroll the page again and again to view the legend.
So please let me know if it is already implemented or add to todo's list.

Control Charts to support manufacturing quality control: X-bar R + I-MR Chart
We would like to be able to generate control charts to show measurements of some property of a product (e.g. mass, thickness, voltage, ppm of a chemical, etc.) over time and also overlay statistical measures line charts including the mean of the sample, ±3σ, UCL (Upper Control Limit - an upper threshold specification value), LCL (Lower Control Limit - a lower threshold specification value), and highlighting data points that may be out of control based on the 7 Wester Electric rules (https://en.wikipedia.org/wiki/Western_Electric_rules). For additional information check out http://asq.org/learn-about-quality/data-collection-analysis-tools/overview/control-chart.html.

Progress through a multi-step process
Not sure what is the name of this type of chart exactly but I need something that visualizes a progress through a multi-step process. Something like this - https://www.vectorstock.com/royalty-free-vector/progress-bar-user-interface-design-vector-16715259.
I couldn't find anything in your examples.1 vote -
Ability to add and remove multiple points
It should be possible to add an array with addPoint() or better to have addPoints(), insertPoints() or addData() where 1) array can be given as argument, 2) insertion index can be given as argument in case the data is already sorted. Or maybe have ability to splice new array to existing series.
More info in related GitHub issue: https://github.com/highcharts/highcharts/issues/4724

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
We can also move the table rows with tasks1 vote -
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.

Global dateTimeLabelFormats configuration
It would be nice if there was a single option that we could apply our dateTimeLabelFormats for all objects that use that option instead of having to copy and paste it separately for tooltip, y-axis, x-axis, etc.

Multiple Opposite X-Axis; One of the X-Axis is grouped
Hi Team,
First of all great work on the Highcharts. It is very helpful in far many way I can describe in representing complex data.
Recently, I have come across a requirement where I need to use Dual-Xaixs of which one is a grouped. i.e for instance, say my bottom X-Axis is of months my top X-Axis should be of quarters (3 months ~ A quarter). I do not see any example or hacks which I can use to achieve this. Please, let me know if this is possible. If so, Please point me in the right direction so that…

Highchart-export-server with zip options
It is hard to keep on increase the maxFieldsSize whenever the highchart throws Error Code 413 - Request Entity Too Large HighCharts.
If highchart export had an option to zip file and then download it might be great option.

Make chart#rangeSelector part of the public API
I asked for chart.rangeSelector to be added to the typescript definitions and was told it's a private class. It can be used as described here: https://stackoverflow.com/questions/48798659/programmatically-set-rangeselector-in-highcharts

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?
