Allow developers to specify different symbols for upper/lower markers in dumbbell charts

[hardingalexh]

Description of the feature

Dumbbell series allow a developer to choose different colors for their low and high markers as color and lowColor. However, there is not an equivalent for marker, which allows the developer to choose which symbol is rendered at the ends of the dumbbell. Allowing a developer to alter lowMarker using identical syntax to marker would allow new features like directional arrows (circle to right arrow) or other custom features for display.

Library related to the feature

Proof of Concept/Live example for the feature

For example, the ability to render a chart like this.

Bump. This is needed for accessibility. Is there no way to accomplish this currently 🤔?
We have a dumbell chart that shows an increase or decrease over two periods. The point for the initial period is a black circle. If the amount has increased, the connector and the upper point are green. If it has decreased, the connector and the lower point are red.
What we want to do is use triangle and upside down-triangle for the second period point to indicate whether it has increased or decreased but we want to keep the initial point a circle.

Hi @gpspake, thanks for popping this up!

This feature request is getting more popular. Imo the Highcharts dumbbell series should handle a case like this in an easy way. I personally came across the same problem with a very basic chart like this one

We'll discuss adding this feature and provide more info soon :)

We'll add it in one of the next releases. No ETA yet, but I'm aiming for the end of Q2 2023
