xyChart: How to change color of a candlestick

In xyChart there is Candlestick renderer. By default it is red or green depending on Open/Close difference sign. Is it possible to change these colors?

Changing of the fill and stroke colors takes no effekt.

You should be able to use deriveFieldsFromData to make this work. You’d use deriveFieldsFromData.fill.color and set it to whatever key has the color value in your data. The manual has an example of it with a Gantt chart.
