    Thank you for sharing the idea. Highcharts generate charts in SVG on the fly. If you want images then you have two possible solutions:

    1. Use canvg that will render chart as bas64 image instead of SVG

    2. Setup your own exporting server (https://www.highcharts.com/docs/export-module/setting-up-the-server) and generate images serverside. Then just use generated png/jpg images in the frontend

    Thanks for sharing the idea, but I'm not quite sure how this should work.

    Did you try using separate series (scatter) with just one point? Or an annotation that can be dragged around?

    Thanks!

    Could you report the issue on related github repo? See: https://github.com/highcharts/map-collection-dist/issues

    Thanks for sharing the idea!

    At this moment, it's possible to use two separate series and connect them using `linkedTo` option. See simple example: https://jsfiddle.net/BlackLabel/qs89y4p6/

    Thanks for sharing the idea!

    Created a simple plugin to achieve that: https://jsfiddle.net/BlackLabel/3bzcasL7/

    Now set `series.zoneKey` and you can use one of: "low", "q1", "median", "q2", "high" values.

    Could you provide a little more details?

    - What do you mean by active selection?
    - How other charts behave?

    Thanks!

    Hi James,

    Navigator accepts the same data as any regular series (line, column etc.). It's designed to improve date-time formats, but you can rework it using some options:

    - change tick positions using tickPositioner: https://api.highcharts.com/highstock/navigator.xAxis.tickPositioner
    - change labels using labels.formatter: https://api.highcharts.com/highstock/navigator.xAxis.labels.formatter

    Kind Regards,
    Paweł Fus

    We don't have such implementation. The demo you posted is a third party solution.

    It's possible to create labels in Highstock, take a look: https://api.highcharts.com/highstock/xAxis.crosshair.label

    Thanks for sharing the idea Benedikt!

    At this moment you can achieve this in two ways:

    - use columnrange series: https://jsfiddle.net/BlackLabel/dsepu7qn/
    - use custom marker.symbol that is just a line: https://api.highcharts.com/highcharts/series.line.marker.symbol

    Hi Antoni,

    It's already possible to define color for each vetor, see a simple demo: https://jsfiddle.net/BlackLabel/borpwsuy/

    What's more, you can use ColorAxis module to automatically colorize vectors according to some other value, for example direction: https://jsfiddle.net/BlackLabel/fwmhydjv/

    Kind Regards,
    Paweł

    Hi @Rahul. Yes, it should be possible to implement all SPC Rules. The only example I have is the one below (where only Rule 1 is added): https://jsfiddle.net/BlackLabel/y74rat0z/

    Paweł Fus commented  · 

    Just in case, it's already possible to create this chart, but we need to calculate all variables on the chart, for example: https://jsfiddle.net/BlackLabel/y74rat0z/ (only Rule 1 applied on a chart).

    Yup, that was just an example for `(min / max)`, updated demo to show the change:`((max - min) / max))` (or `(1 - (min / max))`).

    Demo: https://jsfiddle.net/BlackLabel/bcusgdza/

    Paweł Fus commented  · 

    Can you achieve that % difference from min/max values? If yes, then simply use formatter: https://api.highcharts.com/highstock/annotations.measure.typeOptions.label.formatter

    For example: https://jsfiddle.net/BlackLabel/3chpat2q/ (you can compare `this.startYMin` and `this.startYMax` to check if measure is upward or downward, the same with `startXMin` and `startXMax` to check if user measured to the left or right). Note that demo changes only `measureXY` button in stock tools.

    Simple solution would be to increase padding around the label annotation in a custom control point: https://jsfiddle.net/BlackLabel/foxeumrc/ - it's not exactly the same as html resize though..

    It's not part of the API, but there are three methods to achieve that:

    - yAxis.ticks[tickIndex].collapse()
    - yAxis.ticks[tickIndex].expand()
    - yAxis.ticks[tickIndex].toggleCollapse()

    Demo: https://jsfiddle.net/BlackLabel/fvb681yn/

    Thanks for sharing the idea! Here you can find simple plugin that adds events from `point.events` to links too: http://jsfiddle.net/BlackLabel/b8369zvh/

    Note: You can distinguish nodes and links by simple checking `this.isNode` flag.

    *Internal note:*
    Links are actually points, but hover/tooltip is disabled so default events aren't fired (such link can no be assigned to `chart.hoverPoint` internally).
